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
让我们看另一个例子 −
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
