WebChannelFactory<TChannel> Class

A class for accessing Windows Communication Foundation (WCF) Web services on a client.

Namespace:  System.ServiceModel.Web
Assembly:  System.ServiceModel.Web (in System.ServiceModel.Web.dll)

public class WebChannelFactory<TChannel> : ChannelFactory<TChannel>
where TChannel : class

Type Parameters

TChannel

The type of channel to create.

This class is a special ChannelFactory that automatically adds the WebHttpBehavior to the endpoint if it is not already present. Furthermore, it adds a default WebHttpBinding to the endpoint if the binding is not explicitly configured and the address is an HTTP or HTTPS address.

If all the operations of the contract have no return value or have a return value of type Stream, then the WebChannelFactory<TChannel> configures the binding for the appropriate content type.

The following code shows how to use the WebChannelFactory<TChannel> class to call a WCF service.

Uri baseAddress = new Uri("http://localhost:8000");
WebServiceHost host = new WebServiceHost(typeof(Service), baseAddress);
try
{
    host.Open();

    WebChannelFactory<IService> cf = new WebChannelFactory<IService>(baseAddress);
    IService channel = cf.CreateChannel();
    string s;

    Console.WriteLine("Calling EchoWithGet via HTTP GET: ");
    s = channel.EchoWithGet("Hello, world");
    Console.WriteLine("   Output: {0}", s);

    Console.WriteLine("");

    Console.WriteLine("Calling EchoWithPost via HTTP POST: ");
    s = channel.EchoWithPost("Hello, world");
    Console.WriteLine("   Output: {0}", s);

    Console.WriteLine("");
}
catch (CommunicationException ex)
{
    Console.WriteLine("An exception occurred: " + ex.Message);
}
