razor表单验证

1.验证注解（Model）

public class Student
{
    //默认不能为空
    [Required(ErrorMessage ="姓名不能为空")]
    [StringLength(20)]
    public string Name { get; set; }
    //[RegularExpression(@"[1-9]|([1-9]d)|([1-9]dd)")]
    [Range(1,200,ErrorMessage ="年龄不合法")]
    public int Age { get; set; }
    [DataType(DataType.Password)]
    [Display(Name="密码")]
    public string Password { get; set; }
    [DataType(DataType.Password)]
    [Display(Name="重复密码")]
    [Compare("Password")]
    public string ConFirmPassword { get; set; }
}

 2.生成表单

@{Html.BeginForm("Register", "FormValidate", FormMethod.Post); }
    @*@Html.EditorForModel()*@
    <p>name</p> @Html.TextBox("name") @Html.ValidationMessage("name")<br />
    <p>age</p> @Html.TextBox("age") @Html.ValidationMessage("age")<br />
    <p>password</p>@Html.TextBox("password") @Html.ValidationMessage("password")<br />
    <p>passwordConfirm</p>@Html.TextBox("confirmPassword") @Html.ValidationMessage("confirmPassword")<br />
    @Html.TextBox("sub", "submit", new { type="submit" })
@{Html.EndForm(); }
