关于asp.net:System.Web.UI.ViewStateException，无效的viewstate


System.Web.UI.ViewStateException ,Invalid viewstate

我的网站每天都会抛出以下异常，我找不到解决方案。我很少在网络上做研究，这就是我目前所做的。将下面的选项添加到ASPX并不能解决问题。

ValidateRequest="false" EnableEventValidation="false"
ViewStateEncryptionMode="Never" EnableViewStateMac="false"

另外，我的引用URL是正确的URL，我不知道它如何使用两个(相同)参数进行重定向。在我的推荐页面中没有这样的链接。请帮忙。

更新我已经通过从下面的链接压缩视图状态修复了错误。http://www.codeproject.com/articles/14733/viewstate-compression

并通过将原始方法替换为base-64 char数组错误，修复了无效的长度。

感谢大家的帮助：)

很抱歉，您的站点没有任何内容，您需要尽快重新启用事件验证。

你所看到的是试图通过用你的viewstate发送许多测试号来破解你的站点，试图找到你的哈希键。

你给的IP在过去几天里有一大串的活动。

现在，另一种可能导致此错误的方法是破坏视图状态。如果视图状态太大，可以压缩并拆分它。您还可以禁用所有不需要的控件。此外，您还可以添加一个日志，从内部查看基本页上右侧的内容。

是的，我也喜欢

然后将其粘贴到default.aspx中它需要

导入system.io
