仅验证所需模型

Question

我在一个视图中使用了两个模型，即登录和注册模型。

public class Login
{
    [Required(ErrorMessage ="User ID Required.")]
    public string UserID { get; set; }
    [Required(ErrorMessage ="Password Required")]
    public string Password { get; set; }

}

public class SignUp
{
    [Required (ErrorMessage ="User ID Required")]
    public string UserID { get; set; }

    [Required (ErrorMessage ="Name Required")]
    public string Name { get; set; }

    [Required (ErrorMessage ="Mail ID Required")]
    public string MailID { get; set; }

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

    [Required(ErrorMessage ="Confirm Password Required")]
    [Compare (nameof(Password), ErrorMessage ="Password does not match")]
    public string ConfirmPassword { get; set; }         
}

当我单击“登录”按钮时，它会验证两个模型。如何单独验证模型？

在控制器中使用了以下代码

   public ActionResult Index()
{
    return View();
}
[HttpPost]
public ActionResult Index(string Command, Login Login)
{
    if (Command == "SIGNUP")
    {
        return RedirectToAction("Contact");
    }
    else
    {
        if (ModelState.IsValidField("USERID") && ModelState.IsValidField("PASSWORD"))
        {
            return RedirectToAction("About");
        }               
    }
    return View();
}

Index.cshtml 查看代码：

    @using (Html.BeginForm())

   @Html.AntiForgeryToken()
    @Html.ValidationSummary(true, "", new { @class = "text-danger" })

            </div>
        </div>      
    </div>


}

以上代码放置在使用两个不同模型的视图上。

请帮助并建议我在哪里学习ASP.NET（初级水平）？

您在一个表格中添加 Login 和 SignUp

@using (Html.BeginForm()){
    ...
}

试试这个

<div class="HolderForm">
 @using (Html.BeginForm())
 {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true, "", new { @class = "text-danger" })
    <div class="col-md-6">
        <div class="form-horizontal">
            <h4>Login</h4>
            <hr />

            <div class="form-group">
                <div class="col-md-10">
                @Html.EditorFor(o => o.Login.UserID, new { htmlAttributes = new { @class = "LoginEntry", @placeholder = "USER ID" } })<br>
                @Html.ValidationMessageFor(o => o.Login.UserID,"", new {@class= "LoginValidation" } )
            </div>
        </div>
        <div class="form-group">
            <div class="col-md-10">
                @Html.EditorFor(o => o.Login.Password, new { htmlAttributes = new { @class = "LoginEntry", @placeholder = "PASSWORD" } })<br>
                @Html.ValidationMessageFor(o => o.Login.Password,"", new { @class = "LoginValidation" })

仅验证所需模型

Validate required model only

asp.net-mvc

model-validation
