可能重复：
Setting ViewStateUserKey gives me a “Validation of viewstate MAC failed” error

我已经在StackOverflow上应用了帖子的解决方案但是他们没有解决我的问题。

问题的详细信息是：

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.Web.HttpException: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

我已经尝试将它放在web.config中了：

<pages validateRequest="false" enableEventValidation="false" viewStateEncryptionMode ="Never">

我刚才问了一个类似的问题。你see this post了吗？帮助我解决此错误的另一件事是设置machineKey。请参阅此Microsoft Page about the problem and setting a Machine Key。

Answer 2

我今天开始遇到这个问题。

长话短说 - 我从类似的页面复制了一些表单代码而忘记更改表单操作：

<form id="Form1" action="search.aspx" method="post" runat="server">

</form>

results.aspx上的表格应该是：

<form id="Form1" action="results.aspx" method="post" runat="server">

</form>

我会建议其他人在深入研究配置和其他设置之前检查这个以及任何继承值。
