这是the CartSummary.cshtml
@Html.ActionLink("Cart (" + ViewData["CartCount"] + ")", "Index", "ShoppingCart", new { id = "cart-status" })
@Html.RenderAction("CartSummary", "ShoppingCart");
答案 0 :(得分：14)
鉴于您的CartSummary局部视图，您可能会出现从局部视图调用局部视图的无限循环。
@Html.ActionLink("Cart (" + ViewData["CartCount"] + ")", "Index", "ShoppingCart", new { id = "cart-status" })
//if this is in CartSummary, then it is calling itself over and
//over (or not at all, thus the error.)
@Html.RenderAction("CartSummary", "ShoppingCart");
答案 1 :(得分：8)
请检查您的部分视图是否有错误。 我今天遇到了类似的问题，我的问题是我重命名了模型的属性，并且在视图中没有改变。
也许这也是你的问题。尝试一下。
注意： 我将它发布在答案部分，因为我没有足够的声誉来评论你的问题。
答案 2 :(得分：1)
请从CartSummary.cshtml.Its中删除 @model int 一行。
答案 3 :(得分：0)
今天我遇到了这个问题，事实证明我偶然发现两个部分视图命名相同的东西，并且一个保持递归调用自身，更改另一个部分的名称允许进程再次流动。
答案 4 :(得分：0)
如果出现这样的错误，则意味着处理堆栈中的某个位置存在问题。按继续，完整错误将输出到网页上。
在我的情况下，我收到了异常＆＃34; System.Web.Mvc.HttpHandlerUtil + ServerExecuteHttpHandlerAsyncWrapper＆＃34;，点击继续，然后在网站上显示：
Server Error in '/' Application.
The partial view '_Chat' was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/Home/_Chat.aspx
~/Views/Home/_Chat.ascx
~/Views/Shared/_Chat.aspx
~/Views/Shared/_Chat.ascx
~/Views/Home/_Chat.cshtml
~/Views/Home/_Chat.vbhtml
~/Views/Shared/_Chat.cshtml
~/Views/Shared/_Chat.vbhtml
一旦达到这一点，很容易找到......
答案 5 :(得分：0)
如果我以某个用户身份登录，我的应用程序返回相同的异常。
我发现我的Controller上有一个AuthorizeAttribute，它将操作结果更改为该用户的RedirectToRoute结果，导致System.Web.Mvc.HttpHandlerUtil + ServerExecuteHttpHandlerAsyncWrapper异常，因为从子操作重定向并没有多少SENCE。
我通过对返回redirecttorouteresult的子进程的属性OnAuthorization方法添加一个检查来修复此问题，并将结果重写为EmptyResult。
答案 6 :(得分：0)
就我而言，我只需要检查试图访问的视图上的所有链接。
确保所有控制器Action都具有视图，然后再次运行您的应用程序，一切都会再次正常。
答案 7 :(得分：0)
我也时不时地出现同样的错误/异常。就我而言，这是由于我的某些控制器上有 [RequireHttps]，但不是全部。当有人（通常是机器人或蜘蛛）访问缺少该属性的控制器上的视图时，就会导致此错误/异常。
