获取或设置ArrayList可包含元素的数量，代码如下 −
示例
using System;
using System.Collections;
public class Demo {
public static void Main() {
ArrayList arrList = new ArrayList();
arrList.Add(25);
arrList.Add(50);
arrList.Add(75);
arrList.Add(100);
arrList.Add(125);
arrList.Add(150);
arrList.Add(175);
arrList.Add(200);
arrList.Add(225);
arrList.Add(250);
Console.WriteLine("Elements in ArrayList...");
foreach(int i in arrList) {
Console.WriteLine(i);
}
Console.WriteLine("Count of elements = " + arrList.Count);
Console.WriteLine("Capacity =" + arrList.Capacity);
}
}
输出
这将产生以下输出 −
Elements in ArrayList... 25 50 75 100 125 150 175 200 225 250 Count of elements = 10 Capacity =16
示例
让我们看另一个例子 −
using System;
using System.Collections;
public class Demo {
public static void Main() {
ArrayList arrList = new ArrayList(10);
arrList.Add(25);
arrList.Add(50);
arrList.Add(75);
arrList.Add(100);
Console.WriteLine("Elements in ArrayList...");
foreach(int i in arrList) {
Console.WriteLine(i);
}
Console.WriteLine("Count of elements = " + arrList.Count);
Console.WriteLine("Capacity =" + arrList.Capacity);
}
}
输出
这将产生以下输出 −
Elements in ArrayList... 25 50 75 100 Count of elements = 4 Capacity =10
