Question

即使有几个人问过这个问题，但似乎问题与我的不同。像大多数人似乎得到行号或问题可能是由ViewState引起的。

我正在使用Asp.net 4.0 MVC 2.0，所以我认为我根本不使用ViewState。我的错误没有给我行号很好。所以我不知道是什么导致它或我的代码在哪里。

任何人都知道为什么？

Answer 1

我们将“Response.Redirect”和“return View（）”混合在一起导致了这个问题。浏览器已重定向，但我们仍尝试返回视图...

BAD CODE

    switch (userType)
    {
        case "None":
            Response.Redirect("http://" + host + "/");
            break;
        default:
            Response.Redirect(internalwebhost + "/exit/");
            break;
    }

    return View();

更好的代码

    switch (userType)
    {
        case "None":
            url = "http://" + host + "/";
            break;
        default:
            url = internalwebhost + "/exit/";
            break;
    }

    return new RedirectResult(url);

Answer 2

服务器无法将答案发送给客户端。客户端上丢失的网络连接可能是一个原因。

不确定在非常精确的时间关闭浏览器/标签是否也会出错。

这个错误是什么意思？远程主机关闭了连接。错误代码是0x80070057
