Save You Errors In A Notepad C#

You Could Write It Any Where You Want .

You Could Write It Inside Every Function If You Need To.

I Have Used It Under A Button Click

protected void Button1_Click(object sender, EventArgs e)

        {

            TestClass t = new TestClass();

            DateTime time =  DateTime.Now;

            

            try

            {

                throw new Exception("Sql Error");

            }

            catch (Exception error)

            {

                TextBox1.Text = "" + error.Message;

                t.errorLogger(time.ToString(), "Your Function Name", ""+error.Message);                

            }

        }

 I Have Created A Class Name TestClass and created a object above and 

 called the function inside the class.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

namespace Error_Handling

{

    public class TestClass

    {

        public void errorLogger(string time,string functionName,string errorOccured)

        {

            string lines = "Time : " + time + "  | Function Name : " + functionName + "  | Error Occured : " + errorOccured;

            System.IO.StreamWriter file = new System.IO.StreamWriter("c:\\test.txt", true);

            file.WriteLine(lines);

            file.Close();

        }

    }

}

You will have to specify the path of the notepad above.
