ASP. NET error logs and asp.net error logs

In this article, we will record errors and exceptions on our website through a simple process. In this way, when a program error occurs, the user is redirected to a separate page, and the error is recorded in a text file on the server. When an error occurs, we will record the log every day.

First, I will write a static method to record the Error information to a text file. Here, I will record the Error information to the Error folder on the server. The Code is as follows:

 

Using System. globalization; /// <summary> /// output error information to the txt file // </summary> /// <param name = "errorMessage"> error details </ param> public static void WriteError (string errorMessage) {try {string path = "~ /Error/"+ DateTime. Today. ToString (" yyMMdd ") +". txt "; if (! File. exists (System. web. httpContext. current. server. mapPath (path) {File. create (System. web. httpContext. current. server. mapPath (path )). close ();} using (StreamWriter w = File. appendText (System. web. httpContext. current. server. mapPath (path) {w. writeLine ("\ r \ nLog Entry:"); w. writeLine ("{0}", DateTime. now. toString (CultureInfo. invariantCulture); w. writeLine (errorMessage); w. writeLine ("________________________________________________________________"); w. flush (); w. close () ;}} catch (Exception ex) {WriteError (ex. message );}}
