Error Log Creation Using C# In Asp.Net

Error Log Creation Using C# In Asp.Net So for this first we will create a new asp.net web applicationand add a new page. Now add new class file and add the below code in this class file. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.IO; namespace LogCreator { public class LogManager { public static string PathToCreateLog = System.Configuration.ConfigurationSettings.AppSettings["logpath"].ToString(); public static void CreateLogFile(string Message) { FileInfo fi; FileStream fstr; //Check whether dir exists or not if not then create it #region Try to create the directory. if not extits if (!System.IO.Directory.Exists(PathToCreateLog)) { System.IO.DirectoryInfo di = System.IO.Directory.CreateDirectory(PathToCreateLog); } #endregion string strCurrentDate = DateTime.Now.ToString("yyyyMMdd"); string strFileName = strCurrentDate + "_Log.txt"; //Create New File if not exists if (!System.IO.File.Exists(PathToCreateLog + strFileName)) { fi = new FileInfo(PathToCreateLog + strFileName); fstr = fi.Create(); } //Write the text to the file try { StreamWriter strWriteText = new StreamWriter(PathToCreateLog + strFileName, true); try { strWriteText.WriteLine("`" + DateTime.Now.ToString() + " `, `" + Message + " `"); } catch (Exception ex) { } finally { strWriteText.Dispose(); strWriteText.Close(); } } catch (Exception ex1) { } finally { } } } } In above code i have defined the path in which folder and log text file will get created. In above code log file will get created by date. <add key="logpath" value="C:\LogFiles\"/> You can change the path. Now come to your .aspx page in this page add a text box and button. on button click add the below code. <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>&nbsp; <asp:Button ID="Button1" runat="server" Text="Enter Number and Click" onclick="Button1_Click" /> C# protected void Button1_Click(object sender, EventArgs e) { try { int value = Convert.ToInt32(TextBox1.Text); } catch (Exception ex) { LogManager.CreateLogFile(ex.Message.ToString()); } Now run the page and before that add a new break point. now add some text and press button. As you reach break point you will get error. Now stop debug . Now check the log path which you have defined. and open the text file. ____________________ DOWNLOAD ____________________
