在 C# 中为 ArrayList 创建同步包装器
csharpserver side programmingprogramming
要为 ArrayList 创建同步包装器，代码如下 −
示例
using System;
using System.Collections;
public class Demo {
public static void Main() {
ArrayList arrList = new ArrayList();
arrList.Add("AB");
arrList.Add("CD");
arrList.Add("EF");
arrList.Add("GH");
arrList.Add("IJ");
arrList.Add("KL");
Console.WriteLine("ArrayList elements...");
foreach(string str in arrList) {
Console.WriteLine(str);
}
Console.WriteLine("ArrayList is synchronized? = "+arrList.IsSynchronized);
}
}
输出
这将产生以下输出 −
ArrayList elements... AB CD EF GH IJ KL ArrayList is synchronized? = False
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();
arrList.Add("AB");
arrList.Add("CD");
arrList.Add("EF");
arrList.Add("GH");
arrList.Add("IJ");
arrList.Add("KL");
Console.WriteLine("ArrayList elements...");
foreach(string str in arrList) {
Console.WriteLine(str);
}
Console.WriteLine("ArrayList is synchronized? = "+arrList.IsSynchronized);
ArrayList arrList2 = ArrayList.Synchronized(arrList);
Console.WriteLine("ArrayList is synchronized? = "+arrList2.IsSynchronized);
}
}
输出
这将产生以下输出 −
ArrayList elements... AB CD EF GH IJ KL ArrayList is synchronized? = False ArrayList is synchronized? = True
