    [ServiceKnownType(typeof(DataTable))]
也不行要怎样才能传递dictionary<strin,object>做参数, 而有时object为datatable

我是 c/s模式。服务端以winform做宿主

Answer 3

尽量避免 Dictionary<string, object> 这种设计啊，接口模糊不定。你可以看看这个回答：http://stackoverflow.com/questions/2160052/wcf-service-returning-an-array-of-dictionarystring-object

Answer 4

Datatable不支持序列化，提示对话框说的很清楚了。
