检查 ArrayList 在 C# 中是否具有固定大小
要检查 ArrayList 是否具有固定大小,代码如下 -
示例
using System; using System.Collections; public class Demo { public static void Main(String[] args) { ArrayList list1 = new ArrayList(); list1.Add("One"); list1.Add("Two"); list1.Add("Three"); list1.Add("Four"); list1.Add("Five"); Console.WriteLine("Elements in ArrayList..."); foreach (string res in list1) { Console.WriteLine(res); } ArrayList list = ArrayList.Synchronized(list1); Console.WriteLine("Is ArrayList synchronized? = "+list.IsSynchronized); Console.WriteLine("Is ArrayList have a fixed size? = "+list.IsFixedSize); } }
输出
这将产生以下输出 -
Elements in ArrayList... One Two Three Four Five Is ArrayList synchronized? = True Is ArrayList have a fixed size? = False
示例
让我们看另一个示例 -
using System; using System.Collections; public class Demo { public static void Main(String[] args) { ArrayList list1 = new ArrayList(); list1.Add("ABC"); list1.Add("BCD"); list1.Add("CDE"); list1.Add("DEF"); list1.Add("EFG"); list1.Add("GHI"); list1.Add("HIJ"); list1.Add("IJK"); list1.Add("JKL"); list1.Add("KLM"); Console.WriteLine("Elements in ArrayList..."); foreach (string res in list1) { Console.WriteLine(res); } ArrayList list = ArrayList.Synchronized(list1); Console.WriteLine("Is ArrayList synchronized? = "+list.IsSynchronized); ArrayList list2 = ArrayList.FixedSize(list1); Console.WriteLine("Is ArrayList have a fixed size? = "+list2.IsFixedSize); } }
输出
这将产生以下输出 -
Elements in ArrayList... ABC BCD CDE DEF EFG GHI HIJ IJK JKL KLM Is ArrayList synchronized? = True Is ArrayList have a fixed size? = True
