It works fine for me (other than that your code doesn't compile because you need String.Format(....) inside the exception constructor).
Are you sure there isn't at typo or something in your code? My test code is: // code works fine - string.Compare() returns 0 so no exception string str1 = "-mylife"; string str2 = "-MYLIFE"; if (0 != string.Compare(str1, str2, StringComparison.OrdinalIgnoreCase)) { string msg = string.Format("Compare failed str1:({0}) length:{1} str2:({2}) length:{3}", str1, str1.Length, str2, str2.Length); throw new Exception(msg); } =================================== This list is hosted by DevelopMentorĀ® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
