我在实际网站上收到了一个视图状态错误：感谢任何建议

Answer 1

Viewstate错误的问题在于它们没有告诉您太多并且很难进行故障排除。这件事刚刚开始吗？这有什么事情发生在现场或是可以复制的东西吗？

这是一个开始的地方 http://support.microsoft.com/kb/555353

和另一个 http://weblogs.asp.net/owscott/archive/2004/11/02/What-causes-ViewState-Errors.aspx

Answer 2

问题中的更多信息会很方便。对于每个用户来说，在做某件事时，每次都会发生这种情况吗？或者 - 它只是错误日志中的随机消息，很少发生？

如果是后者，那么看起来有人要么在它被发回给你之前尝试使用ViewState（可能是因为尝试对你的服务器做了一些令人讨厌的事情），或者出于某种原因，ViewState正在为您的访问者损坏。可能是从奇怪的浏览器问题到客户端PC上狡猾的软件吗？！

Answer 3

错误消息包括：

Base-64字符数组的长度无效。

您可以检查您的网页生成的ViewState的长度吗？已知一些浏览器会修剪ViewState，如果它太长了......
