爲什麼fluent.validate扔在asp.net mvc的異常

我想重寫默認asp.net MVC的驗證提交表單so i tried using fluent.validation 爲什麼fluent.validate扔在asp.net mvc的異常

當我創建了一個驗證器類（ProjectValidator）

public class ProjectValidator : AbstractValidator<Project> 
{ 
    public ProjectValidator() 
    { 
     RuleFor(h => h.Application).NotNull().WithName("Application"); 
     RuleFor(h => h.FundingType).NotNull().WithName("Funding Type"); 
     RuleFor(h => h.Description).NotEmpty().WithName("Description"); 
     RuleFor(h => h.Name).NotEmpty().WithName("Project Name"); 
    } 
}

我把一個屬性上我的數據傳輸對象類

[Validator(typeof(ProjectValidator))] 
    public class ProjectViewModel 
    { 
     ... 
    }

，我把這個在的Application_Start（）;

DataAnnotationsModelValidatorProvider 
      .AddImplicitRequiredAttributeForValueTypes = false; 

ModelValidatorProviders.Providers.Add(
      new FluentValidationModelValidatorProvider(new AttributedValidatorFactory()));

但是當我發佈使用這個對象，我得到以下錯誤的一種形式：

Method not found: 'System.Collections.Generic.IEnumerable`1 FluentValidation.IValidatorDescriptor.GetValidatorsForMember(System.String)'.

有什麼建議？

這可能是與您正在使用的程序集版本相關的問題。下面是我用FluentValidation.NET和ASP.NET MVC 3的最新版本的工作步驟：

創建使用默認的Visual Studio模板創建一個新的ASP.NET MVC 3項目。
安裝FluentValidation.MVC3 NuGet包。

添加視圖模型和相應的驗證（請注意，你的情況，你有型項目驗證 - AbstractValidator<Project>而您的視圖模型被稱爲ProjectViewModel這是不一致的驗證器必須關聯到視圖模型）：

public class ProjectValidator : AbstractValidator<ProjectViewModel> 
{ 
    public ProjectValidator() 
    { 
     RuleFor(h => h.Application).NotNull().WithName("Application"); 
     RuleFor(h => h.FundingType).NotNull().WithName("Funding Type"); 
     RuleFor(h => h.Description).NotEmpty().WithName("Description"); 
     RuleFor(h => h.Name).NotEmpty().WithName("Project Name"); 
    } 
} 

[Validator(typeof(ProjectValidator))] 
public class ProjectViewModel 
{ 
    public string Application { get; set; } 
    public string FundingType { get; set; } 
    public string Description { get; set; } 
    public string Name { get; set; } 
}

在Application_Start註冊驗證：

protected void Application_Start() 
{ 
    AreaRegistration.RegisterAllAreas(); 

    RegisterGlobalFilters(GlobalFilters.Filters); 
    RegisterRoutes(RouteTable.Routes); 

    DataAnnotationsModelValidatorProvider.AddImplicitRequiredAttributeForValueTypes = false; 
    ModelValidatorProviders.Providers.Add(new FluentValidationModelValidatorProvider(new AttributedValidatorFactory())); 
}

定義的控制器：

public class HomeController : Controller 
{ 
    public ActionResult Index() 
    { 
     return View(new ProjectViewModel()); 
    } 

    [HttpPost] 
    public ActionResult Index(ProjectViewModel model) 
    { 
     return View(model); 
    } 
}

和一個視圖：

@model Appame.Models.ProjectViewModel 

@using (Html.BeginForm()) 
{ 
    <div> 
     @Html.LabelFor(x => x.Application) 
     @Html.EditorFor(x => x.Application) 
     @Html.ValidationMessageFor(x => x.Application) 
    </div> 
    <div> 
     @Html.LabelFor(x => x.FundingType) 
     @Html.EditorFor(x => x.FundingType) 
     @Html.ValidationMessageFor(x => x.FundingType) 
    </div> 
    <div> 
     @Html.LabelFor(x => x.Description) 
     @Html.EditorFor(x => x.Description) 
     @Html.ValidationMessageFor(x => x.Description) 
    </div> 
    <div> 
     @Html.LabelFor(x => x.Name) 
     @Html.EditorFor(x => x.Name) 
     @Html.ValidationMessageFor(x => x.Name) 
    </div> 

    <input type="submit" value="OK" /> 
}
