我遇到了 Controller 操作至少被调用两次的问题。我有一个 View ，它的布局页面有另一个 View ，并且该 View 被多次调用。如果我删除布局规范，那么该操作将始终执行一次。我浏览了 StackOverflow 和其他网站，但找不到与我的问题具有相同特征的问题，所以我发布了一个新问题。
_ViewStart.cshtml:
@{
Layout = "~/Views/Shared/_ProfileLayout.cshtml";
}
Index.cshtml inside my Profile folder: @{
ViewBag.Title = "Index";
}
Index
Controller Action:
public ActionResult Index()
{
//ToDo: BusinessLogic
//This method gets called twice
//******************//
return View();
}
这似乎是一个简单的问题，我肯定遗漏了一些明显的东西。我已经在这个网站上发布了示例项目:https://skydrive.live.com/#cid=F2DAB940147490B0&id=F2DAB940147490B0%21140
有什么问题吗？
谢谢
更新: View 如下: @{ ViewBag.Title = "TestMVCProject"; 布局=空；

更新: @Tieson T:谢谢，我将其更改为 Html.Partial 而不是 RenderPage。然而，问题仍然存在，因为操作方法仍然被调用两次......(编辑描述，因为我没有添加评论的权限)
最佳答案
我发现了问题。代码中有这一行:
<img alt="TestMVCProject Logo" src="#" width="350" height="150" id="TestMVCProjectLogo" />
src 返回同一页面。一旦我用 "" 替换它，它现在就可以正常工作了。
关于c# - 指定布局时 MVC Controller 操作被调用多次，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/14013505/
