how to start the self hosted wcf service programmatically using c#

ServiceHost host;
      private void StartBtn_Click(object sender, EventArgs e)
      {


          var baseaddress = new Uri[] { new Uri("http://192.168.1.167:8732/Design_Time_Addresses/WcfServiceLibrary1/Service1/") };
          using (host = new ServiceHost(typeof(WcfServiceLibrary1.Service1), new Uri[] { new Uri("http://192.168.1.167:8732/Design_Time_Addresses/WcfServiceLibrary1/Service1/") }))
          {
              // Enable metadata publishing.
              ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
              smb.HttpGetEnabled = true;
              smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
              host.Description.Behaviors.Add(smb);

              // Open the ServiceHost to start listening for messages. Since
              // no endpoints are explicitly configured, the runtime will create
              // one endpoint per base address for each service contract implemented
              // by the service.
              host.AddServiceEndpoint(typeof(WcfServiceLibrary1.IService1), new WSHttpBinding(), "WcfServiceLibrary1.Service1");
              host.Open();

              richTextBox1.AppendText("The service is ready at {0}"+ baseaddress.ToString());
              richTextBox1.AppendText("Press <stop service> to stop the service.");


              // Close the ServiceHost.
              // host.Close();
          }
      }
