Array的应用

用法一：

 static void Main(string[] args)
        {
            int[] myIntArray = new int[] { 1, 2, 3, 4, 5 };
            Object[] myObjArray = new Object[5] { 26, 27, 28, 29, 30 };
            Console.WriteLine("Initially");
            Console.WriteLine("Integer array");
            PrintValues(myIntArray);
            Console.WriteLine("Object Array");
            PrintValues(myObjArray);
            Array.Copy(myIntArray, 2, myObjArray, 3, 2);
            Console.WriteLine("Integer array");
            PrintValues(myIntArray);
            Console.WriteLine("Object Array");
            PrintValues(myObjArray);
            Array.Copy(myObjArray, myObjArray.GetUpperBound(0) - 1, myIntArray, myIntArray.GetUpperBound(0) - 1, 2);
            Console.WriteLine("Integer array");
            PrintValues(myIntArray);
            Console.WriteLine("Object Array");
            PrintValues(myObjArray);
        }
        static void PrintValues(int[] myObjects)
        {
            foreach (int item in myObjects)
            {
                Console.Write("\t{0}", item);

            }
            Console.WriteLine();
        }
         static void PrintValues(Object[] myObjects)
        {
            foreach (object item in myObjects)
            {
                Console.Write("\t{0}", item);

            }
            Console.WriteLine();
        }

用法二：

 Array a = Array.CreateInstance(typeof(int), 2, 3);
            for (int i = 0; i < 2; i++)
            {
                for (int j = 0; j < 3; j++)
                {
                    a.SetValue((i+1) * (j+1), i, j);
                }

            }
            for (int i = 0; i < 2; i++)
            {
                for (int j = 0; j < 3; j++)
                {
                    Console.Write(a.GetValue(i, j)+ " ");
                }
                Console.WriteLine();
                
            }
