Did you know? In C#, you can use a feature called “caller info attributes” to obtain information about the caller of a method. This can be incredibly useful for logging, debugging, or tracing. The attributes CallerMemberName, CallerFilePath, and CallerLineNumber provide information such as the name of the calling method, the path to the source file that contains the caller, and the line number in the source file from which the method was called.
