WCF NetTcp服务仅针对一种特定方法抛出错误

Question

我有一个WCF服务，用于返回没有任何错误的结果。

但是当我调用下面的新方法时，服务会抛出错误。

 [OperationContract]
 IEnumerable<ViewModelClass> GetParameterDetails(int ID, DataType DataType);

[DataContract]
public class ViewModelClass:ParameterBase
{
[DataMember]
 public string Name { get; set; }
 [DataMember]
 public string Source { get; set; }
}

[DataContract]
[KnownType(typeof(ViewModelClass))]
public class ParameterBase
{
[DataMember]
public string ID{ get; set; }
[DataMember]
public Caluculate Type{ get; set; }
}

In service.cs I have,

 public IEnumerable<ViewModelClass> GetParameterDetails(int ID, DataType DataType)
{
 //logic to build the IEnumerable object.
return IEnumerable<ViewModelClass> object.

}

当我在调试模式下运行service时，service.cs方法返回对象正在构建。但是当控制权回到客户端时，服务就会失误：

描述套接字连接已中止。这可能是由于处理消息的错误或远程主机超出接收超时或基础网络资源问题引起的。本地套接字超时为'00：24：59.9989999'。本地IP地址和端口是[fe80 :: b970：d9d6：eb18：3099％11]：64559。远程IP地址和端口是[fe80 :: b970：d9d6：eb18：3099％11]：808。

有人可以指出这个问题的原因吗？
