Examples

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);
}

Dim baseAddress As New Uri("http://localhost:8000")
Dim host As New WebServiceHost(GetType(Service), baseAddress)
Try
    host.Open()

    Dim cf As New WebChannelFactory(Of IService)(baseAddress)
    Dim channel As IService = cf.CreateChannel()
    Dim s As String

    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 ex As CommunicationException
    Console.WriteLine("An exception occurred: " + ex.Message)
End Try

Remarks

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.
