推荐答案
将您的集合作为数组(而不是WCF)返回总是一个好主意.
请在您的申请中检查以下内容
->您的对象内部有一些未初始化的对象,并且没有被序列化.
->将签名从列表转换为数组(始终是避免脏序列化问题的好主意)
Its always a good idea to return your collection as an Array rather a lit from WCF .
Please check the following in your applicaiton
--> Your object has some some uninitialised object internally and its not getting serialized.
--> Convert signature from List to Array (always a good idea to avoid dirty serialization issues )
