c# - 在 net.pipe://localhost/NotifyFullScreen 上没有可以接受消息的端点监听

Question

我遇到了抛出上述异常的问题。我在代码中创建了一个服务器和一个客户端，用于进程间通信。

服务器看起来像这样：

[ServiceContract]
public interface INotifyFullScreen
{
    [OperationContract]
    void NotifyAndonFullScreen();
}

public class NotifyFullScreen : INotifyFullScreen
{
    public void NotifyAndonFullScreen()
    {
        MainWindow.CurrentInstance.NotifyFullScreen();
    }
}

//...NotifyFullScreen() implemented in another class

using (
    var host = new ServiceHost(
    typeof(NotifyFullScreen), new[] { new Uri("net.pipe://localhost/NotifyFullScreen") }))
{
    host.AddServiceEndpoint(
        typeof(INotifyFullScreen), new NetNamedPipeBinding(), "NotifyFullScreen");

    host.Open();
    app = new App();
    app.Run();
    host.Close();
}

...客户端看起来像这样：

[ServiceContract]
public interface INotifyFullScreen
{
    [OperationContract]
    void NotifyAndonFullScreen();
}

//..

var pipeFactory = new ChannelFactory<INotifyFullScreen>(new NetNamedPipeBinding(), new
    EndpointAddress("net.pipe://localhost/NotifyFullScreen"));
var notifyProxy = pipeFactory.CreateChannel();

try
{
    notifyProxy.NotifyAndonFullScreen();
    pipeFactory.Close();
}
catch (Exception ex)
{
    MessageBox.Show("Exception!");
    EventTrace.Default.LogException(ex);
}

每次我尝试在客户端（在 notifyProxy 上）调用方法时，都会出现上述异常。

我究竟做错了什么？非常感谢任何帮助。
