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.

Public Overridable Function GetFileLineNumber As Integer
Dim instance As StackFrame
Dim returnValue As Integer
returnValue = instance.GetFileLineNumber()
public virtual int GetFileLineNumber()
public:
virtual int GetFileLineNumber()
public function GetFileLineNumber() : int
Return Value
Type:
System..::.Int32The file line number.-or- 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.
Dim sf As StackFrame = st.GetFrame(i)
Console.WriteLine(" File: {0}", sf.GetFileName())
Console.WriteLine(" Line Number: {0}", _
sf.GetFileLineNumber())
' 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())
End If
If sf.GetNativeOffset <> StackFrame.OFFSET_UNKNOWN
Console.WriteLine(" Native Offset: {0}", _
sf.GetNativeOffset())
End If
// 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());
}
// Display the stack frame properties.
StackFrame^ sf = st->GetFrame( i );
Console::WriteLine( " File: {0}", sf->GetFileName() );
Console::WriteLine( " Line Number: {0}", sf->GetFileLineNumber().ToString() );
// Note that the column number defaults to zero
// when not initialized.
Console::WriteLine( " Column Number: {0}", sf->GetFileColumnNumber().ToString() );
Console::WriteLine( " Intermediate Language Offset: {0}", sf->GetILOffset().ToString() );
Console::WriteLine( " Native Offset: {0}", sf->GetNativeOffset().ToString() );
