StackFrame.GetFileLineNumber Method

Definition

Namespace:

System.Diagnostics

Assembly:

System.Diagnostics.StackTrace.dll

Source:

StackFrame.cs

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:
 virtual int GetFileLineNumber();

public virtual int GetFileLineNumber ();

abstract member GetFileLineNumber : unit -> int
override this.GetFileLineNumber : unit -> int

Public Overridable Function GetFileLineNumber () As Integer

Returns

Int32

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

Examples

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().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() );

// 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.
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
