get_file_line_number()

virtual xtd::size xtd::diagnostics::stack_frame::get_file_line_number ( ) const

virtualnoexcept

Gets the line number in the file that contains the code that is executing. This information is typically extracted from the debugging symbols for the executable.

Returns

The file line number, or 0 (zero) if the file line number cannot be determined.

Examples

The following example demonstrates the use of the get_file_line_number() method. This code example is part of a larger example provided for the xtd::diagnostics::stack_frame class.

// Display the stack frame properties.
stack_frame sf = st.get_frame(i);
console::write_line(" File: {}", sf.get_file_name());
console::write_line(" Line Number: {}", sf.get_file_line_number());
// Note that the column number defaults to zero when not initialized.
console::write_line(" Column Number: {}", sf.get_file_column_number());
console::write_line(" Method: {}", sf.get_method());
if (sf.get_offset() != stack_frame::OFFSET_UNKNOWN)
  console::write_line(" Offset: {}", sf.get_offset());

csf.cpp, current_stack_frame.cpp, and line_info.cpp.
