Consuming a Web Service in a Windows Application - 2nd Method

• Click Add Reference. Now Service Reference has been added to your project. Create some controls on the design page and write code to call the methods of your web service.
  

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace consumingwebservice
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnadd_Click(object sender, EventArgs e)
{
localhost.Service obj = new localhost.Service();
txtresult.Text = obj.add(Convert.ToInt32(txtfirstno.Text), Convert.ToInt32(txtsecondno.Text)).ToString();
}
private void btnmsgshow_Click(object sender, EventArgs e)
{
localhost.Service obj = new localhost.Service();
MessageBox.Show(obj.msgshow());
}
}
}


You can write the same code in another way by adding NameSpace as YourProjectName.Webreferencename. Look below the full code for this example after adding namespace.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using consumingwebservice.localhost;

namespace consumingwebservice
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnadd_Click(object sender, EventArgs e)
{
localhost.Service obj = new localhost.Service();
txtresult.Text = obj.add(Convert.ToInt32(txtfirstno.Text), Convert.ToInt32(txtsecondno.Text)).ToString();
}
private void btnmsgshow_Click(object sender, EventArgs e)
{
Service obj = new Service();
MessageBox.Show(obj.msgshow());
}
}
}
Run the windows application.

Output:

Write the first and second number and click the "Add" button.



Click the "Message Show" button.
