MVC如何创建一个只允许我对某些字段执行ModelState.IsValid的表单

// 模型
public class MyFormModel
{
    [Required]
    public string Field1 { get; set; }

    public string Field2 { get; set; }

    // 其他字段...
}

// 视图
@model MyFormModel

@using (Html.BeginForm())
{
    @Html.LabelFor(m => m.Field1)
    @Html.TextBoxFor(m => m.Field1)
    @Html.ValidationMessageFor(m => m.Field1)

    @Html.LabelFor(m => m.Field2)
    @Html.TextBoxFor(m => m.Field2)
    @Html.ValidationMessageFor(m => m.Field2)

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

// 控制器
public class MyFormController : Controller
{
    [HttpPost]
    public ActionResult SubmitForm(MyFormModel model)
    {
        // 只对Field1执行ModelState.IsValid验证
        if (ModelState.IsValidField("Field1"))
        {
            // 执行相应的操作
            // ...
            return RedirectToAction("Success");
        }

        // 验证失败，返回表单视图显示错误信息
        return View("Form", model);
    }

    public ActionResult Success()
    {
        return View();
    }
}
