Hello all,

To handle errors in C#, we generally use try, catch and finally methods. but when error occurs in finally block basically three things happens: .

1. The exception rises and it needs to be handled at upper level, but while handling the error our running application may get crashed.
2. The finally block execution gets stopped at the point of error. If there was an error in try block and then again we face an error in finally block then the error of the try block gets lost.

3. To handle such situations , what we can do is , we can keep nested try blocks or put a finally block within a try block.

       {
           protected void Page_Load(object sender, EventArgs e)
           {
               try
               {
                   myFunction();
               }
               catch
               {
                   // catch the exception and log into database
               }
           }

       {
           try { 
               // Do something
           }
           catch {
               // catch the exception and log into database
           }
           finally { 
               // do something
           }
