unsetunset1. 简介unsetunset
介绍FluentValidation的文章不少,零度编程(站长注:原文已失连)的介绍我引用下:
FluentValidation 是一个基于 .NET 开发的验证框架,开源免费,而且优雅,支持链式操作,易于理解,功能完善,还是可与 MVC5、WebApi2 和 ASP.NET CORE 深度集成,组件内提供十几种常用验证器,可扩展性好,支持自定义验证器,支持本地化多语言。
其实它也可以用于WPF属性验证,本文主要也是讲解该组件在WPF中的使用,FluentValidation官网是: https://fluentvalidation.net/ 。
unsetunset2. 本文需要实现的功能unsetunset
提供WPF界面输入验证,采用MVVM方式,需要以下功能:
- 能验证ViewModel中定义的基本数据类型属性:int\string等;
- 能验证ViewModel中定义的复杂属性,比如1)对象属性的子属性,如VM有个学生属性Student,需要验证他的姓名、年龄等,2)集合属性,动态生成表单验证类;
- 能简单提供两种验证样式;
先看实现效果图:
unsetunset3. 调研中遇到的问题unsetunset
简单属性:验证ViewModel的普通属性比较简单,可以参考FluentValidation官网 ,或者国外holymoo大神的代码: UserValidator.cs 。
复杂属性:我遇到的问题是,怎么验证ViewModel中对象属性的子属性?见第二个功能描述,FluentValidation官网有Complex Properties的例子,但是我试了没效果,贴上官方源码截图:
最后我Google到这篇文章,根据该链接代码,ViewModel和子属性都实现IDataErrorInfo接口,即可实现复杂属性验证,文章中没有具体实现,但灵感是从这来的,就不具体说该链接代码了,有兴趣可以点击链接阅读,下面贴上代码。
unsetunset4. 开发步骤unsetunset
4.1. 创建工程、引入库
创建.NET WPF模板解决方案(.Net Framework模板也行)WpfFluentValidation
,引入Nuget包FluentValidation(属性验证使用)和Prism.Wpf
(简化MVVM和命令使用):
<ItemGroup> | |
<PackageReference Include="FluentValidation" Version="11.9.0" /> | |
<PackageReference Include="Prism.Wpf" Version="9.0.271-pre" /> | |
</ItemGroup> |
4.2. 创建测试实体类
4.2.1. 普通类 - Student
此类用作ViewModel中的对象属性使用,学生类包含3个属性:名字、年龄、邮政编码。此实体需要继承IDataErrorInfo接口,用于触发FluentValidation验证使用。
/// <summary> | |
/// 学生实体 | |
/// 继承BindableBase,即继承属性变化接口INotifyPropertyChanged | |
/// 实现IDataErrorInfo接口,用于FluentValidation验证,必须实现此接口 | |
/// </summary> | |
public class Student : BindableBase, IDataErrorInfo | |
{ | |
private int _age; | |
private string? _name; | |
private string? _zip; | |
private readonly StudentValidator _validator = new(); | |
public string? Name | |
{ | |
get => _name; | |
set => SetProperty(ref _name, value); | |
} | |
public int Age | |
{ | |
get => _age; | |
set => SetProperty(ref _age, value); | |
} | |
public string? Zip | |
{ | |
get => _zip; | |
set => SetProperty(ref _zip, value); | |
} | |
public string this[string columnName] | |
{ | |
get | |
{ | |
var validateResult = _validator.Validate(this); | |
if (validateResult.IsValid) | |
{ | |
return string.Empty; | |
} | |
var firstOrDefault = | |
validateResult.Errors.FirstOrDefault(error => error.PropertyName == columnName); | |
return firstOrDefault == null ? string.Empty : firstOrDefault.ErrorMessage; | |
} | |
} | |
public string Error | |
{ | |
get | |
{ | |
var validateResult = _validator.Validate(this); | |
if (validateResult.IsValid) | |
{ | |
return string.Empty; | |
} | |
var errors = string.Join(Environment.NewLine, validateResult.Errors.Select(x => x.ErrorMessage).ToArray()); | |
return errors; | |
} | |
} | |
} |
上面关键代码在public string this[string columnName]
:这里进行输入表单项的数据校验,FluentValidation
调用就在这里,校验逻辑封装在StudentValidator
,表单输入时会实时调用该处代码,columnName
表示表单项的列名,就是ViewModel绑定的属性名。
4.2.2. 集合类 - Field
此类用作ViewModel中的集合项使用,模拟动态表单数据校验,简单包含4个属性:字段名称、字段显示名称、数据类型、数据值,表单主要根据数据类型验证输入的数据值是否合法。同样此实体需要继承IDataErrorInfo接口,用于触发FluentValidation验证使用。
/// <summary> | |
/// 扩展字段,用于生成动态表单 | |
/// 继承BindableBase,即继承属性变化接口INotifyPropertyChanged | |
/// 实现IDataErrorInfo接口,用于FluentValidation验证,必须实现此接口 | |
/// </summary> | |
public class Field : BindableBase, IDataErrorInfo | |
{ | |
private string _value; | |
private readonly FieldValidator _validator = new(); | |
public Field(DataType type, string typeLabel, string name, string value) | |
{ | |
Type = type; | |
TypeLabel = typeLabel; | |
Name = name; | |
Value = value; | |
} | |
/// <summary> | |
/// 数据类型 | |
/// </summary> | |
public DataType Type { get; set; } | |
/// <summary> | |
/// 数据类型名称 | |
/// </summary> | |
public string TypeLabel { get; set; } | |
/// <summary> | |
/// 名称 | |
/// </summary> | |
public string Name { get; set; } | |
/// <summary> | |
/// 值 | |
/// </summary> | |
public string Value | |
{ | |
get => _value; | |
set => SetProperty(ref _value, value); | |
} | |
public string this[string columnName] | |
{ | |
get | |
{ | |
var validateResult = _validator.Validate(this); | |
if (validateResult.IsValid) | |
{ | |
return string.Empty; | |
} | |
var firstOrDefault = | |
validateResult.Errors.FirstOrDefault(error => error.PropertyName == columnName); | |
return firstOrDefault == null ? string.Empty : firstOrDefault.ErrorMessage; | |
} | |
} | |
public string Error | |
{ | |
get | |
{ | |
var validateResult = _validator.Validate(this); | |
if (validateResult.IsValid) | |
{ | |
return string.Empty; | |
} | |
var errors = string.Join(Environment.NewLine, validateResult.Errors.Select(x => x.ErrorMessage).ToArray()); | |
return errors; | |
} | |
} | |
} | |
public enum DataType | |
{ | |
Text, | |
Number, | |
Date | |
} |
看上面代码,public string this[string columnName]
代码处写法和Student
类一样,只是_validator
变量类型不同,前者为StudentValidator
,这里是FieldValidator
,下面我们看看这两个类怎么写。
4.3. 创建验证器
验证属性的写法有两种:
- 可以在实体属性上方添加特性(本文不作特别说明,百度文章介绍很多);
- 通过代码的形式添加,如下方,创建一个验证器类,继承自AbstractValidator,在此验证器构造函数中写规则验证属性,方便管理。
本文使用第二种,通过创建StudentValidator
和FieldValidator
两个验证器类介绍。
4.3.1. StudentValidator
这是学生验证器StudentValidator
,需要继承AbstractValidator
,泛型指定前面需要验证的实体类Student
:
public class StudentValidator : AbstractValidator<Student> | |
{ | |
public StudentValidator() | |
{ | |
RuleFor(vm => vm.Name) | |
.NotEmpty() | |
.WithMessage("请输入学生姓名!") | |
.Length(5, 30) | |
.WithMessage("学生姓名长度限制在5到30个字符之间!"); | |
RuleFor(vm => vm.Age) | |
.GreaterThanOrEqualTo(0) | |
.WithMessage("学生年龄为整数!") | |
.ExclusiveBetween(10, 150) | |
.WithMessage("请正确输入学生年龄(10-150)"); | |
RuleFor(vm => vm.Zip) | |
.NotEmpty() | |
.WithMessage("邮政编码不能为空!") | |
.Must(BeAValidZip) | |
.WithMessage("邮政编码由六位数字组成。"); | |
} | |
private static bool BeAValidZip(string zip) | |
{ | |
if (!string.IsNullOrEmpty(zip)) | |
{ | |
var regex = new Regex(@"\d{6}"); | |
return regex.IsMatch(zip); | |
} | |
return false; | |
} | |
} |
代码简单,使用到数字的大小和范围验证(见Age)、字符串不能为空和长度限制(见Name)、字符串正则表达式验证(见Zip)。
4.3.2. FieldValidator
动态表单数据值校验器,同理需要继承AbstractValidator
,泛型指定前面需要验证的实体类Field
::
public class FieldValidator : AbstractValidator<Field> | |
{ | |
public FieldValidator() | |
{ | |
RuleFor(field => field.Value) | |
.Must((field, value) => (field.Type == DataType.Text && !string.IsNullOrWhiteSpace(field.Value)) | |
|| (field.Type == DataType.Number && double.TryParse(field.Value, out var _)) | |
|| (field.Type == DataType.Date && DateTime.TryParse(field.Value, out var _))) | |
.WithMessage("1.文本不能为空;2.数字类型请填写数字;3.日志类型请填写日期类型"); | |
} | |
} |
这里写的简单了点:
- 文本数据类型,值不能为空;
- 数字数据类型,必须是
double
类型; - 日期类型,必须能使用
DateTime
转换;
本文只做简单演示,可按实际情况修改。
4.3.3. StudentViewModelValidator
这个验证器用于验证ViewModel(后面会写):
public class StudentViewModelValidator : AbstractValidator<StudentViewModel> | |
{ | |
public StudentViewModelValidator() | |
{ | |
RuleFor(vm => vm.Title) | |
.NotEmpty() | |
.WithMessage("标题长度不能为空!") | |
.Length(5, 30) | |
.WithMessage("标题长度限制在5到30个字符之间!"); | |
RuleFor(vm => vm.CurrentStudent).SetValidator(new StudentValidator()); | |
RuleForEach(vm => vm.Fields).SetValidator(new FieldValidator()); | |
} | |
} |
Title
用于关联验证基本数据类型(string类型);CurrentStudent
用于验证对象属性(Student类的实例),设置验证该属性时使用StudentValidator
验证器;Fields
用于验证集合属性(ObservableCollection<Field>
),设置验证该属性子项时使用FieldValidator
验证器,注意前面使用的RuleForEach
表示关联集合中的项验证器。
4.4. ViewModel - StudentViewModel
StudentViewModel
与Student
实体类结构类似,都需要实现IDataErrorInfo
接口,该类由一个简单的string
属性(Title
)和一个复杂的Student
对象属性(CurrentStudent
)、集合属性ObservableCollection<Field> Fields
组成,代码如下:
/// <summary> | |
/// 视图ViewModel | |
/// 继承BindableBase,即继承属性变化接口INotifyPropertyChanged | |
/// 实现IDataErrorInfo接口,用于FluentValidation验证,必须实现此接口 | |
/// </summary> | |
public class StudentViewModel : BindableBase, IDataErrorInfo | |
{ | |
private Student _currentStudent; | |
private string _title; | |
private readonly StudentViewModelValidator _validator; | |
public string Title | |
{ | |
get => _title; | |
set => SetProperty(ref _title, value); | |
} | |
public Student CurrentStudent | |
{ | |
get => _currentStudent; | |
set => SetProperty(ref _currentStudent, value); | |
} | |
public ObservableCollection<Field> Fields { get; } = new(); | |
private DelegateCommand _saveCommand; | |
public DelegateCommand SaveCommand => _saveCommand ??= new DelegateCommand(HandleSaveCommand, | |
HandleCanExecuteSaveCommand); | |
private DelegateCommand _cancelCommand; | |
public DelegateCommand CancelCommand => | |
_cancelCommand ??= new DelegateCommand(HandleCancelCommand, () => true); | |
public StudentViewModel() | |
{ | |
_validator = new StudentViewModelValidator(); | |
CurrentStudent = new Student | |
{ | |
Name = "李刚的儿", | |
Age = 23 | |
}; | |
Fields.Add(new Field(DataType.Text, "文本,比如:四川省成都市场", "地址", "")); | |
Fields.Add(new Field(DataType.Number, "数字,比如:12", "工龄", "")); | |
Fields.Add(new Field(DataType.Date, "时间,比如:2023-09-26 05:13:23", "培训时间", "")); | |
PropertyChanged += Validate; | |
CurrentStudent.PropertyChanged += Validate; | |
foreach (var field in Fields) | |
{ | |
field.PropertyChanged += Validate; | |
} | |
} | |
~StudentViewModel() | |
{ | |
PropertyChanged -= Validate; | |
CurrentStudent.PropertyChanged -= Validate; | |
foreach (var field in Fields) | |
{ | |
field.PropertyChanged -= Validate; | |
} | |
} | |
private void Validate(object sender, PropertyChangedEventArgs e) | |
{ | |
_isCanExecuteSaveCommand = _validator.Validate(this).IsValid; | |
SaveCommand.RaiseCanExecuteChanged(); | |
} | |
private void HandleSaveCommand() | |
{ | |
var validateResult = _validator.Validate(this); | |
if (validateResult.IsValid) | |
{ | |
MessageBox.Show("看到我说明验证成功!"); | |
} | |
else | |
{ | |
var errorMsg = string.Join(Environment.NewLine, | |
validateResult.Errors.Select(x => x.ErrorMessage).ToArray()); | |
MessageBox.Show($"慌啥子嘛,你再检查下输入噻:\r\n{errorMsg}"); | |
} | |
} | |
private bool _isCanExecuteSaveCommand; | |
private bool HandleCanExecuteSaveCommand() | |
{ | |
return _isCanExecuteSaveCommand; | |
} | |
private void HandleCancelCommand() | |
{ | |
MessageBox.Show("我啥都不做,退休了"); | |
} | |
public string this[string columnName] | |
{ | |
get | |
{ | |
var validateResult = _validator.Validate(this); | |
if (validateResult.IsValid) | |
{ | |
return string.Empty; | |
} | |
var firstOrDefault = | |
validateResult.Errors.FirstOrDefault(error => error.PropertyName == columnName); | |
return firstOrDefault == null ? string.Empty : firstOrDefault.ErrorMessage; | |
} | |
} | |
public string Error | |
{ | |
get | |
{ | |
var validateResult = _validator.Validate(this); | |
if (validateResult.IsValid) | |
{ | |
return string.Empty; | |
} | |
var errors = string.Join(Environment.NewLine, validateResult.Errors.Select(x => x.ErrorMessage).ToArray()); | |
return errors; | |
} | |
} | |
} |
ViewModel
属性验证和Student
及Field
类似,这里我加上了保存(SaveCommand
)和取消(CancelCommand
)两个命令,其中保存命令需要所有属性验证通过才可用,通过注册属性的变化事件PropertyChanged
,在变化事件处理程序中验证:
PropertyChanged += Validate; | |
CurrentStudent.PropertyChanged += Validate; | |
foreach (var field in Fields) | |
{ | |
field.PropertyChanged += Validate; | |
} | |
private void Validate(object sender, PropertyChangedEventArgs e) | |
{ | |
_isCanExecuteSaveCommand = _validator.Validate(this).IsValid; | |
SaveCommand.RaiseCanExecuteChanged(); | |
} |
4.5. 视图StudentView
用户直接接触的视图文件来了,比较简单,提供简单属性标题(Title)、复杂属性(包括学生姓名(CurrentStudent.Name)、学生年龄( CurrentStudent .Age)、学生邮政编码( CurrentStudent .Zip))验证、集合属性验证,xaml代码如下:
