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");
