我试图从我的视图的文本框中获取值.

这是我的观点:

    @model MyDataIndexViewModel

@{
    

        

            
Meine Daten
        
    
    var item = Model.User;
        

            
Email
            

                @Html.TextBox("txtEmail", "", new { placeholder = item.Email})
            
        
}


    

        Speichern
    

这是我的控制器:

   [HttpPost]
    public ActionResult Save()
    {
        var email = Request["txtEmail"].ToString();
        return View();
    }

我得到的错误正如标题中所说的那样.先感谢您!

视图:

@model MyDataIndexViewModel


@using (Html.BeginForm("Save", "CONTROLLER_NAME"))
{

    

        
Meine Daten
    

var item = Model.User;
    

        
Email
        

            @Html.TextBox("txtEmail", "", new { placeholder = item.Email, id="txtEmail"})
        
    


    Speichern


}

CONTROLLER

[HttpPost]    
public ActionResult Save()
{
    var email = Request.Form["txtEmail"].ToString();
    return View();
}
