ViewState问题

Question

我们在Windows server2003和IIS6上使用我们的网站，也有一个带有IIS5的测试服务器2003。当我在测试服务器上用ViewState测试页面时，它工作得很好。但是我们在运行IIS6的其他服务器上进行了测试，它给出了错误。我在文件中比较了web配置，它看起来是一样的。有机器密钥和视图状态的最大长度。我已经花了几天时间了，还是找不到。有人能帮我。

这种错误并不总是发生。所以我认为源代码不是问题所在。这是我的错误

Answer 1

我想，如果你的测试服务器运行在你的生产服务器所使用的相同版本的windows和IIS上，那么你的测试服务器可能会更好地发挥它的作用，这一点太明显了。(所以这实际上是一个建议……)

否则，在不深入所有可能导致此问题的问题的情况下，您可以在IIS6中使用IIS5兼容模式。

在IIS中单击网站上的R- Manager

• Service

• check-mark IIS5

SD.LLBLGen.Pro.ORMSupportClasses.EntityBase2类曾经有过一个名为_name的成员吗？这里涉及到负载均衡吗？

看起来ViewState是在一台机器上创建的，在该机器上SD.LLBLGen.Pro.ORMSupportClasses.EntityBase2类有一个_name_ member, and then the ViewState is being interpreted on a machine where that class does not have a_name`成员。
