StackFrame.GetFileLineNumber Method

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.

Namespace:  System.Diagnostics
Assembly:  mscorlib (in mscorlib.dll)

public virtual int GetFileLineNumber()

Return Value

Type: System.Int32
The file line number, or 0 (zero) if the file line number cannot be determined.

The following example demonstrates the use of the GetFileLineNumber method. This code example is part of a larger example provided for the StackFrame class.

// Display the stack frame properties.
StackFrame sf = st.GetFrame(i);
Console.WriteLine(" File: {0}", sf.GetFileName());
Console.WriteLine(" Line Number: {0}", 
   sf.GetFileLineNumber());
// Note that the column number defaults to zero 
// when not initialized.
Console.WriteLine(" Column Number: {0}", 
   sf.GetFileColumnNumber());
if (sf.GetILOffset() != StackFrame.OFFSET_UNKNOWN)
{
   Console.WriteLine(" Intermediate Language Offset: {0}", 
      sf.GetILOffset());
}
if (sf.GetNativeOffset() != StackFrame.OFFSET_UNKNOWN)
{
   Console.WriteLine(" Native Offset: {0}", 
      sf.GetNativeOffset());
}
