WCF服务peoblem?(2路连接) [英] WCF Services peoblem?(2 way connection)
问题描述
我在使用WCF服务的简单的聊天程序。一个服务使用的服务器,另一个用于客户端。这些服务相互连接并相互调用。对于托管服务器,我用了一个窗口服务和客户端我在一个Windows应用程序托管WCF服务。毕竟我发现,简单的计算机此code的工作,但是当移动服务器服务到另一台计算机的异常升高,服务器无法连接到客户端。我搜索并尝试其他方式。 我得到的结果: *如果WCF服务主机Windows应用程序 - 可以不连接到它形成另一个计算机。 *本code保护正常工作,只有当我(在Windows服务托管WCF客户端服务)使用了两个Windows服务 但我想知道如何托管WCF服务在Windows应用程序,可以与其它服务连接和工作? 这是我的code 客户端code: Manager.cs
I have simple chat program using WCF service. One service use for server and another use for client. Those services connect to each other and call each other. For hosting server, I used a windows service and for client I host WCF service in a Windows app. After all I found that this code work on simple computer, but when move server service to another computer an exception raised and server can't connect to the client. I searched and try other ways. I get a result: *IF WCF SERVICE HOST IN WINDOWS APP U CAN'T CONNECT TO IT FORM ANOTHER COMPUTER. *THIS CODE WORKED ONLY WHEN I USED TWO WINDOWS SERVICES (hosting WCF client service in a windows service) But I want to know HOW hosting WCF service in windows app that can connect and work with another services? This is my code Client code: Manager.cs

{
public void SendUserList(string[] users)
{

//when server call this method I have an exception with SSPI
}
public void SendMessage(string message)
{
frmRoom.ReciveMessage = message; // this method called by Server (WCF service which host in windows service)
//when server call this method I have an exception with SSPI

推荐答案
如果您需要使用双向通信,也许你应该看一看的 WCF双面打印服务。
If you need to use 2-way communication, maybe you should take a look at WCF Duplex Services.
