验证失败

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

我已经应用在计算器上的职位的解决方案，但他们并没有对我的问题制定出。

问题的细节是：

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.

我已经试图把这个在web.config：

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

您是否正在运行网络农场？ – Steven 2011-04-13 10:20:13

非常奇怪，我也有类似的问题3天，现在我解决了它。 1.我已使表单认证和有SSL假 <形式defaultUrl = “〜/” loginUrl = “〜/帐户/的Login.aspx” requireSSL = “假” 超时= “2880”/> 2。但在我的httpcookies标签中，我有requireSSL = true。由于在Site.Master.cs它使用cookie来设置ViewStateUserKey，它有问题 3.因此，我得到的错误。 4.我将其修改为错误并重新启动的Web应用程序，现在它很好。 – 2015-02-16 08:02:15

我问过类似的问题，前一阵子。你有see this post吗？另一件帮助我解决这个错误的方法是设置一个machineKey。看到这个Microsoft Page about the problem and setting a Machine Key。

如果您有网上服务器场，则还应该确保站点上的IIS站点ID在服务器之间相匹配。不知何故，这个数字被合并到ViewState的加密中。 – 2014-04-02 19:02:19

今天我开始有这个问题。

长话短说 - 我复制了一些表格的代码从类似的网页，然后忘记变更表单动作：

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

</form>

上results.aspx的形式应该是：

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

</form>

我会建议任何人检查这一点，还有任何继承值之前深入到配置和其他设置。
