Print the source filename and linenumber in C#

Question

Is there any way to retrieve the current source filename and linenumber in C# code and print that value in the console output? Like LINE and FILE

Answer 1

There are no constants defined for that as of now.

The .NET way of doing it is using StackTrace class.

It however works only for Debug builds. So in case you use it, you can have the code using StackTrace between

#if DEBUG
    //your StackTrace code here
#endif

You can read about using #if preprocessors for your DEBUG vs. RELEASE builds in the following Stackoverflow thread.

C# if/then directives for debug vs release

EDIT: Just in case you still need this debugging information in release builds, read the following answer on Stackoverflow:
