要获取或设置ArrayList可以包含的元素数量,代码如下-
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); } }
输出结果
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
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); } }
输出结果
这将产生以下输出-
Elements in ArrayList... 25 50 75 100 Count of elements = 4 Capacity =10
