WCF应用：宿主与调用纯代码示例(Host &Client code only sample)

There are different ways to host a WCF appliaction. You can host it in:

 
  • IIS
  • WAS
  • Windows service
  • console application

The last one is very simple to do and I’ll will showYou how to do it.

First, create a new WCF Service Appliaction project. Then open the IService1.cs interface and add a custom method:

1
2
[OperationContract]
int GetSum(int a, int b);

After that, implement this method in the Service1.svc.cs file. I did it like this:

1
2
3
4
public int GetSum(int a, int b)
 {
 return a + b;
 }

Next create a new Console Application project and fill the Main function with this content:

1
2
3
4
5
6
7
8
9
10
11
12

//Creating a new ServiceHost instance with two base addresses: one for the http and second for the net.tcp
using (ServiceHost sh = new ServiceHost(typeof(WCFAppTest.Service.Service1), new Uri("http://localhost:72/Service"), new Uri("net.tcp://localhost:71/Service")))
 {
 //Adding the endpoints to the ServiceHost
 sh.AddServiceEndpoint(typeof(WCFAppTest.Service.IService1), new NetTcpBinding(), "");
 sh.AddServiceEndpoint(typeof(WCFAppTest.Service.IService1), new WSHttpBinding(), "");
 
 //Creating a new Service Behavior
 ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
 smb.HttpGetEnabled = true;
 sh.Description.Behaviors.Add(smb);
 
 //Opening the ServiceHost for incoming connections
 sh.Open();
 
 System.Console.WriteLine("Waiting for connections...");
 System.Console.ReadLine();
 
 //Close opened ServiceHost object
 sh.Close();
 }

That’s it. Now You have a fully functional WCF Service. TO test it You can create second console project and fill it like this:

1
2
3
4
5
6
7
8

using (ServiceReference1.Service1Client proxy = new ServiceReference1.Service1Client())
 {
 proxy.Endpoint.Address = new System.ServiceModel.EndpointAddress(new Uri("net.tcp://localhost:71/Service"));
 proxy.Endpoint.Binding = new NetTcpBinding();
 proxy.Endpoint.Contract.ContractType = typeof(WCFAppTest.Service.IService1);
 Console.WriteLine("Net.TCP: 1 + 1 is " + proxy.GetSum(1, 1));
 proxy.Close();
 }
 
 using (ServiceReference1.Service1Client proxy = new ServiceReference1.Service1Client())
 {
 proxy.Endpoint.Address = new System.ServiceModel.EndpointAddress(new Uri("http://localhost:72/Service"));
 proxy.Endpoint.Binding = new WSHttpBinding();
 proxy.Endpoint.Contract.ContractType = typeof(WCFAppTest.Service.IService1);
 Console.WriteLine("HTTP: 2 + 2 is " + proxy.GetSum(2, 2));
 proxy.Close();
 }
 
 Console.ReadLine();

ServiceReference1 is a reference You have to add to Your project. Simply do it by clicking RMB on the “Service Reference” node and the “Add Service Reference…”. Next step is to click “Discover” and when Your svc file is found click OK.

OK, now You can run first the service console app and then the test console app and You should see the results like this:
