要检查ArrayList是否同步,代码如下-
using System; using System.Collections; public class Demo { public static void Main(String[] args) { ArrayList list1 = new ArrayList(); list1.Add("A"); list1.Add("B"); list1.Add("C"); list1.Add("D"); list1.Add("E"); list1.Add("F"); list1.Add("G"); list1.Add("H"); list1.Add("I"); Console.WriteLine("Elements in ArrayList1..."); foreach (string res in list1) { Console.WriteLine(res); } ArrayList list2 = new ArrayList(); list2.Add("A"); list2.Add("B"); list2.Add("C"); list2.Add("D"); list2.Add("E"); list2.Add("F"); list2.Add("G"); list2.Add("H"); list2.Add("I"); Console.WriteLine("Elements in ArrayList2..."); foreach (string res in list2) { Console.WriteLine(res); } Console.WriteLine("Is ArrayList synchronized? = "+list2.IsSynchronized); } }
输出结果
这将产生以下输出-
Elements in ArrayList1... A B C D E F G H I Elements in ArrayList2... A B C D E F G H I Is ArrayList synchronized? = False
让我们看另一个例子-
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); } }
输出结果
这将产生以下输出-
Elements in ArrayList... One Two Three Four Five Is ArrayList synchronized? = True
