ModelState.IsValid是否适用于ajax调用？

Question

模型：

public class ChangePasswordModel 
{ 
    //User profile key 
    public string UserName { get; set; } 

    [Required(ErrorMessage = " Please Enter Current Password ")] 
    public string OldPassword { get; set; } 

    [Required(ErrorMessage = " Please Enter a New Password ")] 
    [StringLength(20, MinimumLength = 6, ErrorMessage = "The {0} must be at least {2} and no longer then {1} characters long.")] 
    public string NewPassword { get; set; } 

    [Required(ErrorMessage = " Please Re-enter a New Password ")] 
    [MustBeValidator(MustBeValidator.Condition.EqualTo, "newpassword", ErrorMessage = "Please, confirm password")] 
    public string ReNewPassword { get; set; } 
} 

Ajax调用安全apicontroller：

[System.Web.Mvc.HttpPost] 
    public ActionResult ChangePassword(ChangePasswordModel change) 
    { 

     if (!ModelState.IsValid) 
     { 

的问题是，即使从 “新密码” 差异 “ReNewPassword” 我得到ModelState.IsValid =真

我不知道MustBeValidator是什么，但您可以尝试使用ASP.NET MVC 3中的标准属性：

[Required(ErrorMessage = " Please Re-enter a New Password ")] 
[Compare("NewPassword", ErrorMessage = "Please, confirm password")] 
public string ReNewPassword { get; set; }
