如何在C#中将整个ArrayList复制到一维数组？
要将整个ArrayList复制到一维数组，代码如下-
示例
using System;
using System.Collections;
public class Demo {
public static void Main(){
ArrayList list = new ArrayList();
list.Add("AB");
list.Add("BC");
list.Add("CD");
list.Add("EF");
list.Add("GH");
list.Add("IJ");
list.Add("KL");
list.Add("MN");
String[] strArr = new String[10];
Console.WriteLine("ArrayList...");
foreach(Object obj in list)
Console.WriteLine("{0}", obj);
list.CopyTo(strArr);
Console.WriteLine("\nString Array after copying elements from ArrayList...");
foreach(Object ob in strArr)
Console.WriteLine("{0}", ob);
}
}输出结果
这将产生以下输出-
ArrayList... AB BC CD EF GH IJ KL MN String Array after copying elements from ArrayList... AB BC CD EF GH IJ KL MN
示例
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);
list.Add(300);
list.Add(400);
list.Add(500);
list.Add(600);
list.Add(700);
list.Add(800);
list.Add(900);
list.Add(1000);
int[] intArr = new int[10];
Console.WriteLine("ArrayList...");
foreach(Object obj in list)
Console.WriteLine("{0}", obj);
list.CopyTo(intArr);
Console.WriteLine("\nInteger Array after copying elements from ArrayList...");
foreach(Object ob in intArr)
Console.WriteLine("{0}", ob);
}
}输出结果
这将产生以下输出-
ArrayList... 100 200 300 400 500 600 700 800 900 1000 Integer Array after copying elements from ArrayList... 100 200 300 400 500 600 700 800 900 1000
