Error Handling in Windows Application Using C#.Net

9/13/2014 - By Pranav Singh 0

In this article I will show you how you can handle error in windows application using c#.net. This will help your user to enter correct data.


So for this article first we will create a new windows application and in this form  we will add a button and a text box and a button control.



Now go to code end and add the below code to validate the textbox value.

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 WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        //Error handeling in windows app;lkication using c#.net
        private void button1_Click(object sender, EventArgs e)
        {
            string dataMesage = Validationmessage();
            if (dataMesage == "")
            {
                MessageBox.Show("Your name is : " + txtname.Text);
            }
            else
            {
                MessageBox.Show(dataMesage, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
        }
        public string Validationmessage()
        {
            string dataMesssage = "";
            if (txtname.Text == "")
            {
                dataMesssage = "Please enter name.";
            }
            return dataMesssage;
        }
    }
}

So here is the output.
