要将整个ArrayList复制到从指定索引开始的一维数组,代码如下-
using System; using System.Collections; public class Demo { public static void Main(){ ArrayList list = new ArrayList(); list.Add("PQ"); list.Add("RS"); list.Add("TU"); list.Add("UV"); list.Add("WX"); list.Add("YZ"); Console.WriteLine("ArrayList elements..."); for (int i = 0; i < list.Count; i++) { Console.WriteLine(list[i]); } String[] strArr = new String[6] {"One", "Two", "Three", "Four", "Five", "Six"}; Console.WriteLine("\nArray elements..."); for (int i = 0; i < strArr.Length; i++) { Console.WriteLine(strArr[i]); } list.CopyTo(strArr, 0); Console.WriteLine("\nArray elements (updated)..."); for (int i = 0; i < strArr.Length; i++) { Console.WriteLine(strArr[i]); } } }
输出结果
这将产生以下输出-
ArrayList elements... PQ RS TU UV WX YZ Array elements... One Two Three Four Five Six Array elements (updated)... PQ RS TU UV WX YZ
现在让我们来看另一个示例-
using System; using System.Collections; public class Demo { public static void Main(){ ArrayList list = new ArrayList(); list.Add(100); list.Add(200); Console.WriteLine("ArrayList elements..."); for (int i = 0; i < list.Count; i++) { Console.WriteLine(list[i]); } int[] intArr = new int[5] {10, 20, 30, 40, 50}; Console.WriteLine("\nArray elements..."); for (int i = 0; i < intArr.Length; i++) { Console.WriteLine(intArr[i]); } list.CopyTo(intArr, 0); Console.WriteLine("\nArray elements (updated)..."); for (int i = 0; i < intArr.Length; i++) { Console.WriteLine(intArr[i]); } } }
输出结果
这将产生以下输出-
ArrayList elements... 100 200 Array elements... 10 20 30 40 50 Array elements (updated)... 100 200 30 40 50
