Show Complete Compilation Source:

这是CartSummary.cshtml

@Html.ActionLink("Cart (" + ViewData["CartCount"] + ")",new { id = "cart-status" })

    @Html.RenderAction("CartSummary","ShoppingCart");

解决方法

给定您的CartSummary部分视图,看起来您处于从局部视图调用部分视图的某种无限循环中.

@Html.ActionLink("Cart (" + ViewData["CartCount"] + ")",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");
