我们在网站注册的时候往往需要在用户注册完毕的时候显示用户名是否可用,这就要用到模型的远程校验了。具体如下。

     [Required(ErrorMessage = "用户名不能为空"), Remote("ValidateUserName", "CommonWebApi", AreaReference.UseRoot, ErrorMessage = "用户名已被占用")]
[StringLength(, ErrorMessage = "{0} 至少包含 {2} 个字符。", MinimumLength = )]
[Display(Name = "用户名")]
public string UserName { get; set; }
Remote方法实现了远程校验。
