我刚刚更新到 .NET 3.5 SP1,我曾经工作的 ASP.NET MVC 页面现在已经停止工作。

尝试加载页面时,我得到以下 YSOD

[CryptographicException: Padding is invalid and cannot be removed.]

如果我删除线

<%= Html.AntiForgeryToken() %>

一切都恢复正常了,有什么想法可能导致这种情况吗?如果这是 MVC 或 .NET 问题,我本来希望找到解决方案的运气更好,所以我猜这与我的配置有关。

我尝试重新安装 MVC 框架,看看是否是因为我在 SP1 之前安装,但我仍然遇到同样的问题。Google 和 SO 搜索尚未得出任何确定的结论。

呵呵,刚刚解决了。

清除了我的浏览器缓存和 cookie,一切正常。

如果站点已部署并且您正在进行维护,包括 ASP.NET MVC 程序集更新,则不能选择清除浏览器缓存。这是我使用的解决方案:

@Html.AntiForgeryTokenReset() @* use this instead*@

这是扩展方法

public static MvcHtmlString AntiForgeryTokenReset(this HtmlHelper htmlHelper)
{
    try
    {
        return htmlHelper.AntiForgeryToken();
    } catch (Exception ex)
    {
        var request = HttpContext.Current.Request;
        request.Cookies.Clear();
        return htmlHelper.AntiForgeryToken();
    }
}
