How to display the line number in which the error occurs in try catch?

Question

C++ / C#

The code:

try {
...
}
catch (Exception error)
 {
     addToLog("Error 43: " + error.Message + " : " + error.StackTrace);
 }

In case of an error, it displays:
Error 43: Object reference does not point to an instance of an object.: in the name of the Method
How to display the number of the line in which the error occurs? or something else that will help determine exactly where the error is
