我可以控制用户授权，包括表单、两个文本框和提交按钮。此控件通过 RenderAction 方法包含在母版页中。我有注册页面（通过 RenderBody 方法包含的视图）也有表单。当我从注册表单提交数据时，也会触发登录控件并调用其处理程序（用于处理 POST 数据的控制器方法）。您可以在下面看到用于授权的控制器方法。从其他表单提交数据后，如何防止将 POST 数据发送到登录控件？

        [HttpPost]
        public RedirectResult LogIn(AuthViewModel authResult)
        {
            if (ModelState.IsValid)
            {
                userService.LogInUser(authResult.Login, authResult.Password, Request.UserHostAddress);
            }
            else
            {
                TempData["AuthMessage"] = GetValidationMessage();
            }
            string redirectUrl = "/";
            if (Request.UrlReferrer != null)
            {
                redirectUrl = Request.UrlReferrer.AbsoluteUri.ToString();
            }
            return Redirect(redirectUrl);

        }

        [HttpGet]
        [ChildActionOnly]
        public PartialViewResult LogIn()
        {
            if (userService.IsUserLoggedIn())
            {
                User currentUser = userService.GetLoggedInUser();
                ViewBag.LoggedInMessage = currentUser.FullName + "(" + currentUser.Login + ")";
            }
            return PartialView("AuthControl");
        }

授权控制：

@model AuthViewModel

<div class="rounded-corners auth-panel">
    @if (ViewBag.LoggedInMessage == null)
    {
        <div class="auth-container">
            @using (Html.BeginForm("LogIn", "Navigation"))
            {
                <div>
                    <label for="Login">
                        Login:
                    </label>
                    @Html.TextBoxFor(m => m.Login, new { @class="middle-field"})
                </div>
                <div>
                    <label for="Password">
                        Password:
                    </label>
                    @Html.PasswordFor(m => m.Password, new { @class="middle-field"})
                </div>
                <div class="in-center">
                    <input type="image" src="@Url.Content("~/Content/Images/submit.png")"/>
                </div>
            }
        </div>

        <div class="error-msg">
            @if (TempData["AuthMessage"] != null)
            { 
                @Html.Raw(TempData["AuthMessage"].ToString())
            }
            @Html.ValidationSummary()
         </div>
        <div class="small-nav-message">
            <a href="#" class="registration-link">Registration</a>

    }

注册页面：

RegistrationViewModel

@{
    ViewBag.Title = "Registration";
}
@if (TempData["RegistrationFinished"] == null || !(bool)TempData["RegistrationFinished"])
{
<div class="post content-holder">
    <div class="fields-holder">

在注册视图中，更改

@using (Html.BeginForm())

至

@using (Html.BeginForm("Index", "Registration"))

在单个控制器、单个动作的场景中，不需要额外的特定路由信息，但显然路由引擎无法通过多个控制器/动作自行确定要路由到哪个控制器/动作。

根据评论编辑：

所以这是一个路由问题。尝试为您的注册操作添加特定路线。就像是

routes.MapRoute(
    "Register", // Route name
    "{controller}/Index/{registrationResult}", // URL with parameters
    new { 
        controller = "{controller}", 
        action = "Selector", 
        registrationResult= UrlParameter.Optional
        }
);

'registrationResult' 将是 post Action 中的参数名称。我认为视图模型非常相似，路由引擎无法区分两者。在默认路由之前添加上述路由，提交注册表时应匹配。

为了解决我的问题，我从控制器上下文中检查 IsChildAction 属性。我还必须清除模型状态。

        [HttpPost]
        public ActionResult LogIn(AuthViewModel authResult)
        {
            if (!this.ControllerContext.IsChildAction)
            {
                if (ModelState.IsValid)
                {
                    userService.LogInUser(authResult.Login, authResult.Password, Request.UserHostAddress);
                }
                else
                {
                    TempData["AuthMessage"] = GetValidationMessage();
                }
                string redirectUrl = "/";
                if (Request.UrlReferrer != null)
                {
                    redirectUrl = Request.UrlReferrer.AbsoluteUri.ToString();
                }
                return Redirect(redirectUrl);
            }
            ModelState.Clear();
            return PartialView("AuthControl");
        }
