第1步：创建接口
namespace WCF.Interface
{
//[ServiceContract(CallbackContract=typeof(ICallback))]//回调接口(全双工)
[ServiceContract]
public interface ICalculator
{
[OperationContract]
double Add(double x, double y);
}
}第2步：实现接口服务
namespace WCF.Service
{
[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)]
public class Calculator : ICalculator
{
#region ICalculator Members
public double Add(double x, double y)
{
double result = x + y;
#region 全双工回调
//ICallback callback = OperationContext.Current.GetCallbackChannel<ICallback>();
//callback.DisplayResult(x, y, result);
#endregion
return result;
}
#endregion
}
}第3步：建立WinForm服务端
#region 通过代码直接定义和开启服务
/// <summary>
/// 通过代码直接定义和开启服务(在启动之前必须把相应的配置文件注释或删除)
/// </summary>
private void HostCalculatorServiceViaCode()
{
try
{
Uri httpBaseAddress = new Uri("http://localhost:8888/Calculator");//1、基于http
Uri tcpBaseAddress = new Uri("net.tcp://localhost:9999/Calculator");//2、基于tcp
calculatorSerivceHost = new ServiceHost(typeof(Calculator), httpBaseAddress, tcpBaseAddress);
BasicHttpBinding httpBinding = new BasicHttpBinding();
NetTcpBinding tcpBinding = new NetTcpBinding();
Type type1 = typeof(ICalculator);
calculatorSerivceHost.AddServiceEndpoint(type1, httpBinding, "");
calculatorSerivceHost.AddServiceEndpoint(type1, tcpBinding, "");
ServiceMetadataBehavior behavior = calculatorSerivceHost.Description.Behaviors.Find<ServiceMetadataBehavior>();
if (behavior == null)
{
behavior = new ServiceMetadataBehavior();
behavior.HttpGetEnabled = true;
calculatorSerivceHost.Description.Behaviors.Add(behavior);
}
else
{
behavior.HttpGetEnabled = true;
}
calculatorSerivceHost.Opened += delegate
{
txt_info.AppendText("Calculator server has begain to listen ...使用cmd命令 netstat -aon|findstr "9999" 查看 ...
");
};
calculatorSerivceHost.Open();
}
catch (Exception ex)
{
MessageBox.Show("详细信息：" + ex.Message,"出错提示，请确保参数配置正确且端口不被占用！", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
#endregion
第4步：建立Web服务端
namespace WCF.WebServer
{
// 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码、svc 和配置文件中的类名“Calculator”。
/// <summary>
/// wcf服务应用程序，测试时端口为 7777 并启动服务网站
/// 继承于Service.Calculator,不用写额外代码直接调用
/// </summary>
public class Calculator :WCF.Service.Calculator
{
}
}第5步：客户端调用WinForm和Web服务端显示结果
private void InvocateCalclatorServiceViaCode()
{
System.ServiceModel.Channels.Binding httpBinding = new BasicHttpBinding();
System.ServiceModel.Channels.Binding tcpBinding = new NetTcpBinding();
EndpointAddress httpAddress = new EndpointAddress("http://localhost:8888/Calculator");//WinForm基于http的通道
EndpointAddress tcpAddress = new EndpointAddress("net.tcp://localhost:9999/Calculator");//WinForm基于tcp的通道
EndpointAddress webhttpAddress = new EndpointAddress("http://localhost:7777/Calculator.svc");//Web服务
txt_info.AppendText("
Invocate self-host calculator service... ...");
#region Invocate Self-host service
CalculatorClient calculator_http = new CalculatorClient(httpBinding, httpAddress);
CalculatorClient calculator_webhttp = new CalculatorClient(httpBinding, webhttpAddress);
CalculatorClient calculator_tcp = new CalculatorClient(tcpBinding, tcpAddress);
try
{
txt_info.AppendText("
Begin to invocate calculator service via http transport... ...");
txt_info.AppendText(string.Format("
x + y = {2} where x = {0} and y = {1}", 1, 2, calculator_http.Add(1, 2)));
txt_info.AppendText("
Begin to invocate calculator service via tcp transport... ...");
txt_info.AppendText(string.Format("
x + y = {2} where x = {0} and y = {1}", 1, 2, calculator_tcp.Add(1, 2)));
txt_info.AppendText("
Begin to invocate calculator service via webhttp transport... ...");
txt_info.AppendText(string.Format("
x + y = {2} where x = {0} and y = {1}", 1, 2, calculator_webhttp.Add(1, 2)));
}
catch (Exception ex)
{
txt_info.AppendText(Environment.NewLine + ex.Message);
}
finally
{
calculator_http.Close();
calculator_tcp.Close();
}
#endregion
#region Invocate IIS-host service
//txt_info.AppendText("

//EndpointAddress httpAddress_iisHost = new EndpointAddress("http://localhost/wcfservice/CalculatorService.svc");
