在我的_Layout.cshtml视图中

My aim is be able to load a view model into my _LoginPartial view. 我的目标是能够将视图模型加载到_LoginPartial视图中。 So I have added the following to my AccountController class 所以我在我的AccountController类中添加了以下内容
[ChildActionOnly]
public ActionResult _LoginPartial()
{
ApplicationUser user = null;
ManageUserViewModel model = null;
string userID = User.Identity.GetUserId() ?? String.Empty;
if (!String.IsNullOrEmpty(userID))
{
user = UserManager.FindById(userID);
model = new ManageUserViewModel();
model.IsAdmin = user.IsAdmin;
}
return PartialView(model);
}
But this does not call this method from 但这不会从
@Html.Action("_LoginPartial", "Account")`
I have read this answer and have swapped the 我已阅读此答案并交换了
@Html.Action("_LoginPartial", "Account")
to 至
@Html.Action("_LoginPartial", "Account", new { area = "" })
as the controller is not in the "Shared" folder. 因为控制器不在“共享”文件夹中。 I have also tried 我也尝试过
@Html.Action("_LoginPartial", "Account", new { area = "Controllers" })`
but I am just getting a browser error: 但我只是遇到浏览器错误：
The page isn't redirecting properly
What am I doing wrong here? 我在这里做错了什么？
Thanks for your time. 谢谢你的时间。
Edit. 编辑。 following @markpSmith's suggestion, I have attempted to use 按照@markpSmith的建议，我尝试使用
@{ Html.RenderAction("_LoginPartial", "Account"); }
_but this give the same error. _但这给出了相同的错误。 _ _

Use @Html.Partial("_LoginPartial") 使用@Html.Partial("_LoginPartial")
You don't need to specify action in Controller as you can access User.Identity in View so update _LoginPartial with User.Identity instead of Model. 您无需在Controller中指定操作，因为您可以在View中访问User.Identity，因此用User.Identity而不是Model更新_LoginPartial。

I can't see if you have attempted the: 我看不到您是否尝试过：
@Html.RenderPartial()
ActionMethod (see MSDN ) ActionMethod（请参阅MSDN ）
making yours look similar to: 使您的外观类似于：
View: 视图：
@Html.RenderPartial("_LoginPartial","Account")
Controller: 控制器：
(within AccountController) （在AccountController中）
public ActionResult _LoginPartial()
{
ApplicationUser user = null;
ManageUserViewModel model = null;
string userID = User.Identity.GetUserId() ?? String.Empty;
if (!String.IsNullOrEmpty(userID))
{
user = UserManager.FindById(userID);
model = new ManageUserViewModel();
model.IsAdmin = user.IsAdmin;
}
return PartialView(model);
}
Other than that, I would suggest removing the underscore and see if you can run it instead (since it is a partial view, I don't think it will be navigateable anyway) 除此之外，我建议删除下划线并查看是否可以运行它（因为它是局部视图，所以我认为无论如何它都无法导航）
