如何在 WCF 中 return IEnumerable？现有连接被远程主机强行关闭

Question

我尝试了 return WCF 服务中的 IEnumerable

IService1.cs

[OperationContract] 
IEnumerable GetAllTasks(string PersonName);

Service1.cs

MyEntities db=new MyEntities ();
private IEnumerable getAllTask;

public IEnumerable GetAllTasks(string PersonName)
{
      getAllTask= db.GetAllTaskOfPerson(PersonName).ToList();
      return getAllTask;
}

客户

Service.ServiceClient ws=new Service.ServiceClient().ToList();
grid.DataSource=ws.GetAllTasks("John");
grid.DataBind();

我收到此错误：

An existing connection was forcibly closed by the remote host

尝试使您的 IEnumerable 成为强类型集合。在 operationcontract

的签名中使用 Collection<T> 或 List<T> 时，Wcf 表现良好
