我的一些页面出现错误：
错误消息：Base-64 字符串中的无效字符。错误来源：mscorlib 错误目标站点：Byte[] FromBase64String(System.String)
错误消息：无法验证数据。错误来源：System.Web 错误目标站点：Byte[] GetDecodedData(Byte[], Byte[], Int32, Int32, Int32 ByRef)
错误消息：无效的视图状态。错误来源：System.Web 错误目标站点：System.String DecryptStringWithIV(System.String, System.Web.Configuration.IVType)
这是一些上下文。如果您看到任何东西，请告诉我。我认为这部分是由我的 asp 向导控制引起的。
