String Writer

In simple applications or pages, handling an exception will not be a difficult task. But when your application is using any web services or threading, most of the time, actual exception details will be stored in InnerException of the main Exception object. In such cases, we need to iterate all the inner exceptions to get the actual error message.

Here is a code snippet to iterate all inner exceptions from the root Exception object.

private List<string> GetAllErrMessages(Exception ex)
{
   List<string> messages = new List<string>();
   //assign the current exception as first object and then loop through its
   //inner exceptions till they are null
   for(Exception eCurrent = ex.Exception; eCurrent != null; eCurrent = eCurrent.InnerException)
   {
      messages.Add(eCurrent.Message);
   }
}

My team said they never saw any code like handling Exception objects using for loop. I don’t know but I learnt this from my lead when I was working on Adrenalin HRMS product. Just sharing the code for your review
