创建 C# 中的 Hashtable 同步包装器
要创建 Hashtable 的同步包装器,代码如下 −
示例
using System; using System.Collections; public class Demo { public static void Main() { Hashtable hash = new Hashtable(); hash.Add("1", "AB"); hash.Add("2", "CD"); hash.Add("3", "EF"); hash.Add("4", "GH"); hash.Add("5", "IJ"); hash.Add("6", "KL"); Console.WriteLine("Hashtable elements..."); foreach(DictionaryEntry d in hash) { Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value); } Console.WriteLine("Hashtable is synchronized? = "+hash.IsSynchronized); } }
输出
这将生成以下输出 −
Hashtable elements... Key = 1, Value = AB Key = 2, Value = CD Key = 3, Value = EF Key = 4, Value = GH Key = 5, Value = IJ Key = 6, Value = KL Hashtable is synchronized? = False
示例
我们来看另一个示例 −
using System; using System.Collections; public class Demo { public static void Main() { Hashtable hash = new Hashtable(); hash.Add("1", "Mark"); hash.Add("2", "Gary"); hash.Add("3", "Jacob"); hash.Add("4", "Andy"); hash.Add("5", "Jack"); Console.WriteLine("Hashtable elements..."); foreach(DictionaryEntry d in hash) { Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value); } Console.WriteLine("Hashtable is synchronized? = "+hash.IsSynchronized); Hashtable hash2 = Hashtable.Synchronized(hash); Console.WriteLine("Hashtable is synchronized? = "+hash2.IsSynchronized); } }
输出
这将生成以下输出 −
Hashtable elements... Key = 1, Value = Mark Key = 2, Value = Gary Key = 3, Value = Jacob Key = 4, Value = Andy Key = 5, Value = Jack Hashtable is synchronized? = False Hashtable is synchronized? = True
