In managed C++ you could do that as follows: bool areEqual = true; if (list->Count > 0) { String ^ first = list[0]; for (int i = 1; i Count; i++) { if (list[i] != first) { areEqual = false; break; } } } if(areEqual) { // do something } else { // do something else }

Hi Try this public static bool IsUniqueFast(List arrs) //Pass your List Here { List arrCopy = arrs.ConvertAll (delegate(T tf) { return tf; }); arrCopy.Sort(); // Sort Before you Compare for (int i = 0; i { if (arrCopy[i].Equals(arrCopy[i + 1])) return false; } return true; } ---------------------------------------- If this helps you then mark as Correct Answer
