Question

For logging purposes

__LINE__  __FILE__  

were my friends in C/C++. In Java to get that information I had to throw an exception and catch it. Why are these old standbys so neglected in the modern programming languages? There is something magical about their simplicity.

It is uglier, but you can do something like this in C# using the StackTrace and StackFrame classes:

StackTrace st = new StackTrace(new StackFrame(true)); Console.WriteLine(' Stack trace for current level: {0}', st.ToString()); StackFrame sf = st.GetFrame(0); Console.WriteLine(' File: {0}', sf.GetFileName()); Console.WriteLine(' Method: {0}', sf.GetMethod().Name); Console.WriteLine(' Line Number: {0}', sf.GetFileLineNumber()); Console.WriteLine(' Column Number: {0}', sf.GetFileColumnNumber()); 

Of course, this comes with some overhead.
