如何将数据从WCF服务推送到客户端应用程序

本文介绍了如何将数据从WCF服务推送到客户端应用程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在 Windows窗体应用程序上托管了 WCF服务。 我有一个客户端应用程序（Windows窗体应用程序）。 我想将数据从客户端应用程序发送到托管WCF服务的Windows窗体应用程序。 这是我的代码： IMyService.cs

I have a WCF Service Hosted on Windows Forms Application. I have a Client Application(Windows forms application). I want to send data from Client application to the Windows Forms Application where WCF Service is hosted. Here is my code: IMyService.cs

[DataContract] public class DataMessage { [DataMember] public string Name { get; set; } } [ServiceContract] public interface IService1 { [OperationContract] string GetMessage(string name); [OperationContract] void BroadcastToClient(DataMessage eventData); }

客户代码：

Client Code:

ServiceReference1.Service1Client client; DataMessage message = new DataMessage(); message.Name = textBox1.Text; client.BroadcastToClient(message);

我应该在 Service.cs 中添加什么，以便将数据推送到托管的应用程序。 我尝试过： 服务。 cs：

What should I add in Service.cs, so that this pushes the data to the hosted Application. What I have tried: Service.cs:

public void BroadcastToClient(DataMessage eventData) { MessageBox.Show(eventData.Name); }

我添加了Messagebox来查看它是否从客户端应用程序接收数据，以及工作正常... 现在我想将它发送到托管应用程序。

I have added Messagebox to just see whether its receiving the data from client Application, and its working fine... Now I want to send it to Hosted Application.
