c# - .Net 2 中的反序列化列表 <> 应该在 .Net 4 中工作吗？

Question

从 .Net 4 应用程序到 .Net 2 应用程序进行远程调用时出现以下错误。

Unable to load type System.Collections.Generic.List`1[[MyNamespace.MyClass, MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]] required for deserialization.

有谁知道这是否可能是因为List<T>引起的？ .Net 2 和 .Net 4 有什么不同？

此外，MyClass有 3 string和 3 DateTime属性并标记为 [Serializable]但不执行 ISerializable

这是堆栈跟踪:

似乎问题出在加载您的类型上:

MyNamespace.MyClass, MyAssembly

.NET 框架需要在List<T> 中加载类型T能够序列化列表。所以问题是您的程序集或您的类型未正确加载到另一个对等点中。

您应该了解为什么抛出错误的机器无法加载包含类型 MyNamespace.MyClass, MyAssembly 的程序集。

另外，确保类型 MyNamespace.MyClass, MyAssembly具有相同的版本号。

您可以使用 Fusion Log tool 查看程序集加载失败.希望对您有所帮助。
