Capture line number with exception message in asp.net C#

Sometime, i am writing a long code for implement for some logic in my program and inside my code, multiple try-catch block is exist, then i don't know proper error exception for capture message type. So i have capture all information for generated error.

Add below code in your function:

// Get stack trace for the exception with source file information

var st = new StackTrace(ex, true);

// Get the top stack frame

var frame = st.GetFrame(0);

// Get the line number from the stack frame

var line = frame.GetFileLineNumber();
