要在ArrayList中的一系列元素上复制集合的元素,代码如下-
using System;
using System.Collections;
public class Demo {
public static void Main(){
ArrayList arrList = new ArrayList();
arrList.Add("A");
arrList.Add("B");
arrList.Add("C");
arrList.Add("D");
Console.WriteLine("ArrayList elements...");
for (int i = 0; i < arrList.Count; i++) {
Console.WriteLine("" + arrList[i]);
}
string[] str = { "Demo", "Text" };
arrList.SetRange(0, str);
Console.WriteLine("After copying...");
for (int i = 0; i < arrList.Count; i++) {
Console.WriteLine("" + arrList[i]);
}
}
}输出结果
这将产生以下输出-
ArrayList elements... A B C D After copying... Demo Text C D
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 arrList = new ArrayList();
arrList.Add("One");
arrList.Add("Two");
arrList.Add("Three");
arrList.Add("Four");
arrList.Add("Five");
arrList.Add("Six");
arrList.Add("Seven");
arrList.Add("Eight");
Console.WriteLine("ArrayList elements...");
for (int i = 0; i < arrList.Count; i++) {
Console.WriteLine("" + arrList[i]);
}
string[] str = { "Demo", "Text" };
arrList.SetRange(2, str);
Console.WriteLine("After copying...");
for (int i = 0; i < arrList.Count; i++) {
Console.WriteLine("" + arrList[i]);
}
}
}输出结果
这将产生以下输出-
ArrayList elements... One Two Three Four Five Six Seven Eight After copying... One Two Demo Text Five Six Seven Eight
