Question

我只是问自己是否有可能从HttpGet Actionmethod获取值并将它们传递给HttpPost Action方法。

以下是代码：

ContactAdminController

public class ContactAdminController : Controller
    {
        [HttpGet]
        public ActionResult SendMail()
        {
            return View();
        }

        [HttpPost]
        public ActionResult SendMail(ContactAdminViewModel contactAdmin)
        {

            if (ModelState.IsValid)
            {
                if (DQL.CheckUsernameAndEmail(contactAdmin.username, contactAdmin.email))
                {
                    Mail.SendMail.SendForgotPassword(contactAdmin.username, contactAdmin.email, contactAdmin.message);
                    return RedirectToAction("LogIn", "Account");
                }
            }
            else
            {
                ModelState.AddModelError("", "Your username is not associated with the email adress");
                return RedirectToAction("LogIn", "Account");
            }

            return RedirectToAction("LogIn", "Account");
        }

    }

SendMail.cshtml

@model MvcApplication1.ViewModels.ContactAdminViewModel
@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <title>SendMail</title>
</head>
<body>
    <div>
        <p>
            @Html.LabelFor(m => m.username, "username")
            @Html.EditorFor(m => m.username)
            @Html.ValidationMessageFor(m => m.username)
        </p>
        <p>
            @Html.LabelFor(m => m.email, "email")
            @Html.EditorFor(m => m.email)
            @Html.ValidationMessageFor(m => m.email)
        </p>
        <p>
            @Html.LabelFor(m => m.message, "Your message")
            <p>
                @Html.TextAreaFor(m => m.message, new { cols = "35", rows = "10", @style = "resize:none" })
                @Html.ValidationMessageFor(m => m.message)
            </p>
        </p>

        <p>
            @Html.ActionLink("Send", "SendMail", "ContactAdmin")
        </p>
    </div>
</body>
</html>

ContactAdminViewModel

public class ContactAdminViewModel
    {
        [Required(ErrorMessage = "You need to fill in a username")]
        public string username { get; set; }
        [Required(ErrorMessage = "You need to fill in an email adress")]
        public string email { get; set; }
        [Required(ErrorMessage = "You need to fill a message for the admin")]
        public string message { get; set; }
    }

我的问题是我真的不知道如何将值从EditorFors和TextAreaFor传递给HttpPost SendMail方法。我没有在stackoverflow上找到任何合适的东西，也没有从asp.net主页找到任何解决方案。我希望有人可以帮助我:) 提前致谢

您没有创建要提交给控制器的表单，不是吗？您可以使用BeginForm FormExtension这样的

在Razor中执行此操作

@using (Html.BeginForm("SendMail", "ContactAdmin", FormMethod.Post))
{
   //Your form here with submit button
}

此方法将开放<form>标记写入响应。当用户提交表单时，请求将由操作方法处理。
您可以在using块中使用此方法。在这种情况下，该方法会在使用块的末尾呈现结束</form>标记。
此方法有许多重载，但这允许定义FormMethod：处理表单的HTTP方法，GET或POST。

因此，如果您想POST到控制器，SendMail.cshtml将成为

@using (Html.BeginForm("SendMail", "ContactAdmin", FormMethod.Post))
    {
<div>
        <p>
            @Html.LabelFor(m => m.username, "username")
            @Html.EditorFor(m => m.username)
            @Html.ValidationMessageFor(m => m.username)
        </p>
        <p>
            @Html.LabelFor(m => m.email, "email")
            @Html.EditorFor(m => m.email)
            @Html.ValidationMessageFor(m => m.email)
        </p>
        <p>
            @Html.LabelFor(m => m.message, "Your message")
            <p>
                @Html.TextAreaFor(m => m.message, new { cols = "35", rows = "10", @style = "resize:none" })
                @Html.ValidationMessageFor(m => m.message)
            </p>
        </p>
        <p>
            <input type="submit" class="button" value="Send" />
        </p>
    </div>
}
