在ASP.NET MVC C#中验证表单

public class MyFormModel
{
    [Required(ErrorMessage = "姓名是必填项")]
    public string Name { get; set; }

    [EmailAddress(ErrorMessage = "请输入有效的电子邮件地址")]
    public string Email { get; set; }

    [Range(18, 99, ErrorMessage = "年龄必须在18到99之间")]
    public int Age { get; set; }
}

@model MyFormModel

@using (Html.BeginForm())
{
    @Html.LabelFor(m => m.Name)
    @Html.TextBoxFor(m => m.Name)
    @Html.ValidationMessageFor(m => m.Name)

    @Html.LabelFor(m => m.Email)
    @Html.TextBoxFor(m => m.Email)
    @Html.ValidationMessageFor(m => m.Email)

    @Html.LabelFor(m => m.Age)
    @Html.TextBoxFor(m => m.Age)
    @Html.ValidationMessageFor(m => m.Age)

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

[HttpPost]
public ActionResult SubmitForm(MyFormModel model)
{
    if (ModelState.IsValid)
    {
        // 表单验证通过，可以进行后续操作
        // 例如保存数据到数据库或发送电子邮件等
        return RedirectToAction("Success");
    }

    // 表单验证失败，返回视图显示错误信息
    return View(model);
}
