                        lasterror.AppendLine(ex.StackTrace);
                        lasterror.AppendLine();
                    }
                    
                    lblException.Text = lasterror.ToString();

What do you mean by "want to get the exact issue of exception"?
The Exception object and int InnerException property (if any) provides all the information, so I'm confused as to exactly what you are having difficulty with.

if (ex != null)
If you are inside the catch block, then by definition ex must be a reference to the exception.; i.e. it cannot be null.
