要将整个 ArrayList 复制到从指定索引开始的一维数组，代码如下 −
示例
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("
Array elements...");
for (int i = 0; i < strArr.Length; i++) {
Console.WriteLine(strArr[i]);
}
list.CopyTo(strArr, 0);
Console.WriteLine("
Array elements (updated)...");
for (int i = 0; i < strArr.Length; i++) {
Console.WriteLine(strArr[i]);
}
}
}
输出
这将产生以下输出 −
ArrayList elements... PQ RS TU UV WX YZ 数组元素... One Two Three Four Five Six Array elements (updated)... PQ RS TU UV WX YZ
示例
现在让我们看另一个例子 −
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("
Array elements...");
for (int i = 0; i < intArr.Length; i++) {
Console.WriteLine(intArr[i]);
}
list.CopyTo(intArr, 0);
Console.WriteLine("
Array elements (updated)...");
for (int i = 0; i < intArr.Length; i++) {
Console.WriteLine(intArr[i]);
}
}
}
输出
这将产生以下输出 −
ArrayList elements... 100 200 数组元素... 10 20 30 40 50 Array elements (updated)... 100 200 30 40 50
