Description Michal 2012-02-09 04:48:11 UTC
System.Diagnostics.StackFrame.GetILOffset always returns 0 (zero).

Sample code:
private static void GetStackTrace(this Exception exception, StringBuilder output)
{
 try
 {
  var stackTrace = new StringBuilder();
  var st = new System.Diagnostics.StackTrace(exception);

  foreach (var sf in st.GetFrames())
  {
   var method = sf.GetMethod();

   var parameters = new StringBuilder();
   foreach (var p in method.GetParameters())
   {
    parameters.AppendFormat("{0}, ", p);
   }
   if (parameters.Length > 0)
    parameters.Remove(parameters.Length - 2, 2);

   stackTrace.Insert(0, String.Format("at {0}.{1}({2}) [0x{3:x8}]\n",
    method.ReflectedType.FullName, method.Name, parameters, sf.GetILOffset()));
  }

  output.AppendLine(stackTrace.ToString());
 }
 catch
 {
  output.AppendLine(exception.StackTrace);
 }
}

This is by design, you must compile and run with debug enabled.
