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> .Net 2和.Net 4有什么不同？

此外,MyClass有3个字符串和3个DateTime属性,并标记为[Serializable]但不实现ISerializable

这是堆栈跟踪：

解决方法:

似乎问题是加载你的类型：

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在另一个对等方中正确加载.

您应该进行工作以了解抛出错误的计算机无法加载包含MyNamespace.MyClass,MyAssembly类型的程序集的原因

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

您可以使用Fusion Log tool查看装配负载故障.希望它有所帮助.
