【问题描述】：
我有一个使用 WCF 服务的简单聊天程序。一种服务用于服务器，另一种用于客户端。这些服务相互连接并相互调用。对于托管服务器，我使用了 Windows 服务，对于客户端，我在 Windows 应用程序中托管 WCF 服务。毕竟我发现这段代码可以在简单的计算机上运行，但是当将服务器服务移动到另一台计算机时，会引发异常并且服务器无法连接到客户端。我搜索并尝试了其他方法。 我得到一个结果： *如果 WCF 服务主机在 WINDOWS 应用程序中，您无法从另一台计算机连接到它。 *此代码仅在我使用两个 WINDOWS 服务时才有效（在 Windows 服务中托管 WCF 客户端服务） 但我想知道如何在可以连接和使用其他服务的 Windows 应用程序中托管 WCF 服务？ 这是我的代码 客户端代码： 管理器.cs
public delegate void UserInfoHandeler(string UserName);
public delegate void MessageHandeler(string Message);
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class Manager : IClientPoint
{
public void SendUserList(string[] users)
{
frmRoom.Members = users; // this method called by Server (WCF service which host in windows service)
//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
}
FrmJoin frmJoin;
FrmRoom frmRoom;
ChatServerClient ServiceInvoker;
public string User
{
get;
set;
}
public void Run()
{
frmJoin = new FrmJoin();
frmJoin.LoginEvent += new UserInfoHandeler(frmJoin_LoginEvent);
ServiceInvoker = new ChatServerClient("WSHttpBinding_ChatServer", Settings.Default.ChatServerAddress);
frmJoin.ShowDialog();
}
void frmJoin_LoginEvent(string UserName)
{
frmRoom = new FrmRoom();
frmRoom.SendMessageEvent += new MessageHandeler(frmRoom_SendMessageEvent);
frmJoin.LogoutEvent += new UserInfoHandeler(frmJoin_LogoutEvent);
User = UserName;
frmRoom.ReciveMessage = ServiceInvoker.Login(User, Settings.Default.ClientPointAddress);
frmRoom.ShowDialog();
}
void frmJoin_LogoutEvent(string UserName)
{
string message = ServiceInvoker.Logout(UserName, Settings.Default.ChatServerAddress);
}
void frmRoom_SendMessageEvent(string Message)
{
ServiceInvoker.SendMessage(User, Message);
} }
