推荐答案

您做这个失去保障福利，但最快的解决办法是设置 enableViewStateMac =false的在web.config中。

You lose security benefits by doing this, but the quickest solution would be to set enableViewStateMac="false" in the web.config.

<pages enableViewStateMac="false" ...>

这有时会发生，如果你的ViewState是非常大的，你投递的页面加载完成之前。如果你使用ViewState的作为数据存储库，这可能是为什么发生这种情况。我还要检查您的标记，并确保你没有任何未关闭的＆LT;脚本＆GT; 标记。

This can sometimes happen if your ViewState is very large, and you postback before the page has finished loading. If you're using ViewState as a data repository, that's probably why this happens. I would also inspect your markup and make sure that you don't have any unclosed <script> tags.
