C#中数组初始化与数组元素复制的方法

using System; 
public class ArraySample
{
 public static void Main()
 {
   // 创建和初始化数组
   int[] intArr = new int[5] {1,2,3,4,5};
   Object[] objArr = new Object[5] {10,20,30,40,50};
   foreach (int i in intArr)
   {
   Console.Write(i);
   Console.Write(",");
   }
   Console.WriteLine();
   foreach (Object i in objArr )
   {
   Console.Write (i);
   Console.Write (",");
   }
   Console.WriteLine();
   // 复制 intArr的前三个元素到 objArr
   Array.Copy(intArr, objArr,3);
   Console.WriteLine("After coping" );
   foreach (int i in intArr)
   {
   Console.Write(i);
   Console.Write(" , ");
   }
   Console.WriteLine( );
   foreach (Object i in objArr)
   {
   Console.Write(i);
   Console.Write(" ,");
   }
   Console.WriteLine( );
 }
}
