private void button1_Click(object sender, EventArgs e)

    //   want to call web-service from here and want to print response in   
    //   any text box.                
}

There are numerous methods to do this in C#, For your simple example, a WebClient -Call should do what you want.

private void button1_Click(object sender, EventArgs e)
{
    var client = new WebClient();
    var response = client.DownloadString("http://localhost:8000"); // or whatever your url might look like

    myTextBox.Text = response;
}
