C#的Array对象自带反转功能,但是下面的代码完全通过自定义的算法来实现数组反转
public static void ReverseArray<T>(this T[] inputArray) { T temp = default(T); if (inputArray == null) throw new ArgumentNullException("inputArray is empty"); if (inputArray.Length > 0) { for (int counter = 0; counter < (inputArray.Length / 2); counter++) { temp = inputArray[counter]; inputArray[counter] = inputArray[inputArray.Length - counter - 1]; inputArray[inputArray.Length - counter - 1] = temp; } } else { Trace.WriteLine("Reversal not needed"); } }
