doubt in my winApplication using WCF service

private void button1_Click(object sender, EventArgs e)
        {
            //manual wcf service link for this Application
            WSHttpBinding binding = new WSHttpBinding();
            EndpointAddress endpoint = new EndpointAddress(new Uri("http://197.168.0.11//WcfSample1/Service1.svc"));
            Service1Client Client1 = new Service1Client(binding,endpoint);
            MessageBox.Show(Client1.GetData(Convert.ToInt16(textBox1.Text)));
        }

<pre lang="c#">
private void button1_Click(object sender, EventArgs e)
        {
            Service1Client Client1 = new Service1Client();
            MessageBox.Show(Client1.GetData(Convert.ToInt16(textBox1.Text)));
        }
