WCF 服務、托管、用戶端 簡單案例

1、定義服務
[ServiceContract]
 public interface IServiceClass
 {
 [OperationContract]
 string GetText();

 [OperationContract]
 int MultiplyNumbers(int firstvalue, int secondvalue);
 }

 public class ServiceClass : IServiceClass
 {
 string IServiceClass.GetText()
 {
 StreamReader sw = new StreamReader(@"c:\WCFServiceTest.txt");
 return sw.ReadLine();
 //return "Hello World";
 }

 int IServiceClass.MultiplyNumbers(int firstvalue, int secondvalue)
 {
 return firstvalue * secondvalue;
 }

 }2、托管
 private void Form1_Load(object sender, EventArgs e)
 {

 Uri bpa = new Uri("net.pipe://localhost/NetNamedPipeBinding");
 Uri tcpa = new Uri("net.tcp://localhost:8000/TcpBinding");

 sh = new ServiceHost(typeof(ServiceClass), bpa, tcpa);
 //sh = new ServiceHost(typeof(ServiceClass), tcpa);

 NetNamedPipeBinding pb = new NetNamedPipeBinding();
 NetTcpBinding tcpb = new NetTcpBinding();

 ServiceMetadataBehavior mBehave = new ServiceMetadataBehavior();
 sh.Description.Behaviors.Add(mBehave);
 sh.AddServiceEndpoint(typeof(IMetadataExchange), 
 MetadataExchangeBindings.CreateMexTcpBinding(), "mex");

 sh.AddServiceEndpoint(typeof(IMetadataExchange), 
 MetadataExchangeBindings.CreateMexNamedPipeBinding(), "mex");

 sh.AddServiceEndpoint(typeof(IServiceClass), pb, bpa);
 sh.AddServiceEndpoint(typeof(IServiceClass), tcpb, tcpa);

 sh.Open();

 label1.Text = "Service Running";
 }3、用戶端調用
private void button2_Click(object sender, EventArgs e)
 {
 switch (_Selection)
 {
 case 0:
 TCP.ServiceClassClient client = new 
 WCFClientApp.TCP.ServiceClassClient("NetTcpBinding_IServiceClass");
 textBox2.Text = client.MultiplyNumbers(5, 5).ToString();
 break;

 case 1:
 NamedPipe.ServiceClassClient client1 = new 
 WCFClientApp.NamedPipe.ServiceClassClient("NetNamedPipeBinding_IServiceClass");
 textBox2.Text = client1.MultiplyNumbers(5, 5).ToString();
 break;

 case 2:
 break;
 }
 }
