Here is the code structre: 

```
 try
    {
       --outter code block;

       try
         { 
            --inner code block;
         }

        catch(Exeption ex)
        {
          throw new Exception() 
          --inner catch block
        }
    }
    catch(Exeption ex) 
    {
       --outter catch block
    }    

```

How can I determine in outter catch block if exception generated in **outter code block** or throwed in inner catch block?
