我在收到此错误之前所做的修改。我在所有课程中都已更改byte[]为。Stream

由于缺乏对您要达到的目标的解释，您是否已更新所有消费者以使用新类？我想你已经改变了数据合同和这个破碎的消费者。

如果不是，我会查看您传输了多少数据，请参阅此博客文章！似乎这就是问题所在。

我遇到了一些问题，可能是配置问题，或者如果您在 IIS 中托管，则存在有关权限的问题，请尽可能详细说明。

如果您期望从调用的方法返回并使用 WCF 服务，则此错误背后的一个可能原因可能是您的对象序列化/反序列化问题。如果您的服务方法返回不可序列化的内容，那么您的代理通道会出现此错误。

为避免这种情况，只需检查-

  1. 返回类型并确保它是可序列化的。您可能必须将 [Serializable] 属性与您的类一起放置。
  2. Have [DataMember(IsRequired=true)]，它告诉值将在序列化时出现（它说下划线属性是不可为空的值类型）。
  3. 确保您的枚举值与存储在表中的值匹配。这是非常危急的情况，因为您没有预料到。
