工作流程4持久性，反序列化错误

问题描述

大家好

我有一个WF4活动，我已成功将其持久保存到Sql数据库，但是当尝试加载以前保存的实例时，我收到以下异常:

反序列化程序无法加载要反序列化的类型，因为在程序集中找不到类型"System.Activities.Location`1 [[MYTYPE，MYASSEMBLY，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null]]" System.Activities，版本= 4.0.0.0，文化=中性，PublicKeyToken = 31bf3856ad364e35''.检查要序列化的类型与要反序列化的类型具有相同的协定，并使用相同的程序集.

"MYTYPE"类是MYASSEMBLY中包含的POCO.

感谢收到的任何帮助，


谢谢

Hi all

I have a WF4 activity which I am successfully persisting to an Sql database, however when attempting to load the previously persisted instance I receive the following exception:

The deserializer cannot load the type to deserialize because type ''System.Activities.Location`1[[MYTYPE, MYASSEMBLY, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]'' could not be found in assembly ''System.Activities, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35''. Check that the type being serialized has the same contract as the type being deserialized and the same assembly is used.

The "MYTYPE" class is a POCO contained within MYASSEMBLY.

Any help gratefully received,


Thanks

推荐答案

private Assembly AppDomain_AssemblyResolve(object sender, ResolveEventArgs e)
{
   if (e.Name == "MYTYPE, MYASSEMBLY, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null")
   {
       return Assembly.Load("MYTYPE, MYASSEMBLY, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null");
   }

   return null;
}
