title: Can we throw a custom exception from catch block?
body: <p>I want to throw a custom exception from catch block, i.e., whenever any exception occurs it should catch by catch block and will throw a custom exception. I am trying with the below code but getting runtime exception in catch block as "unhandled exception".</p>
  
  <pre><code>try{
    ///some error
   }
        catch(Exception e){
      try{
            throw new CustomException("Exception1", e);
          }
      catch(CustomException ce)
         {
          Console.WriteLine("Custom Exception Caught" + ce.StackTrace);
  
         }
   }
  
  
  public class CustomException : Exception
   {
  
     public CustomException : base()
      {
      }
  
    public CustomException(string message, Exception innerException) : base(message, innerException)
     {
       processError(message, innerException);
     }
   }
  
   public static void processError(string mgs, Exception e)
    {
     switch(mgs)
      {
       case "Exception1":
          Console.WriteLine("Exception1 caught" + e.StackTrace);
          break;
       case "Exception2":
          Console.WriteLine("Exception2 caught" + e.StackTrace);
          break;
       default:
          Console.WriteLine("Some other Exception caught" + e.StackTrace);
          break;
         }
      }
  </code></pre>
  
  <p>Any hint on the above problem is highly appreciated. Thanks in advance.</p>
