Error Handling in Windows Application Using C#.Net

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.

Some of my previous articles are as follows: Restrict User to Enter Only Negative, Non-Negative and Decimal Number in TextBox Using C#.Net in Windows Application, Dynamically Add textbox control on button click in windows application using C#.net and VB.net, Paging in DataGridview Using C#.Net In Windows Application, Show Progressbar While Moving Folder File From One Directory To Other Using C#.Net In Windows Application, Windows Application - Excel Sheet Name in C#.Net, WaterMark TextBox In Windows Applications Using C# and VB.Net.

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.
