Asp.net mvc 3 asp.net mvc3中的自定义验证程序

我在asp.net mvc3应用程序中创建了一个自定义验证器，如下所示：

{
  if (customerToValidate.FirstName == customerToValidate.LastName)
            return new ValidationResult("First Name and Last Name can not be same.");

        return ValidationResult.Success;
    }

    public static ValidationResult ValidateFirstName(string firstName, ValidationContext context)
    {
        if (firstName == "Nadeem")
        {
            return new ValidationResult("First Name can not be Nadeem", new List<string> { "FirstName" });
        }
        return ValidationResult.Success;
    }

[CustomValidation(typeof(CustomerValidator), "ValidateCustomer")]
public class Customer
{
    public int Id { get; set; }

    [CustomValidation(typeof(CustomerValidator), "ValidateFirstName")]
    public string FirstName { get; set; }

    public string LastName { get; set; }
}

@model CustomvalidatorSample.Models.Customer
@{
    ViewBag.Title = "Index";
}
<h2>
    Index</h2>
@using (@Html.BeginForm())
{
    @Html.ValidationSummary(false)

    <div class="editor-label">
        @Html.LabelFor(model => model.FirstName, "First Name")
    </div>

    <div class="editor-field">
        @Html.EditorFor(model => model.FirstName)
    </div>


    <div class="editor-label">
        @Html.LabelFor(model => model.LastName, "Last Name")
    </div>

    <div class="editor-field">
        @Html.EditorFor(model => model.LastName)
    </div>

    <div>
    <input type="submit" value="Validate" />
    </div>
}

我的看法是这样的：

{
  if (customerToValidate.FirstName == customerToValidate.LastName)
            return new ValidationResult("First Name and Last Name can not be same.");

        return ValidationResult.Success;
    }

    public static ValidationResult ValidateFirstName(string firstName, ValidationContext context)
    {
        if (firstName == "Nadeem")
        {
            return new ValidationResult("First Name can not be Nadeem", new List<string> { "FirstName" });
        }
        return ValidationResult.Success;
    }

[CustomValidation(typeof(CustomerValidator), "ValidateCustomer")]
public class Customer
{
    public int Id { get; set; }

    [CustomValidation(typeof(CustomerValidator), "ValidateFirstName")]
    public string FirstName { get; set; }

    public string LastName { get; set; }
}

@model CustomvalidatorSample.Models.Customer
@{
    ViewBag.Title = "Index";
}
<h2>
    Index</h2>
@using (@Html.BeginForm())
{
    @Html.ValidationSummary(false)

    <div class="editor-label">
        @Html.LabelFor(model => model.FirstName, "First Name")
    </div>

    <div class="editor-field">
        @Html.EditorFor(model => model.FirstName)
    </div>


    <div class="editor-label">
        @Html.LabelFor(model => model.LastName, "Last Name")
    </div>

    <div class="editor-field">
        @Html.EditorFor(model => model.LastName)
    </div>

    <div>
    <input type="submit" value="Validate" />
    </div>
}

@model CustomvalidatorSample.Models.Customer
@{
ViewBag.Title=“Index”；
}
指数
@使用（@Html.BeginForm（））
{
@Html.ValidationSummary（false）
@Html.LabelFor（model=>model.FirstName，“First Name”）
@EditorFor（model=>model.FirstName）
@Html.LabelFor（model=>model.LastName，“LastName”）
@EditorFor（model=>model.LastName）
}

但验证不会启动。请提出解决方案

谢谢

你怎么知道验证没有启动？您是否在控制器中设置断点

您没有在视图中显示任何验证错误。您需要将以下行添加到视图中

@Html.ValidationMessageFor(model => model.FirstName)
@Html.ValidationMessageFor(model => model.LastName)

您将希望从类中删除自定义验证。但请将其保留在属性上
