Check if Hashtable is synchronized C#
To check if Hashtable is synchronized, the code is as follows −
Example
using System; using System.Collections; public class Demo { public static void Main() { Hashtable hash = new Hashtable(); hash.Add("One", "Katie"); hash.Add("Two", "John"); hash.Add("Three", "Barry"); hash.Add("Four", ""); hash.Add("Five","Harry"); hash.Add("Six", "F"); hash.Add("Seven", "Tom"); hash.Add("Eight","Andy"); hash.Add("Nine", "I"); hash.Add("Ten", "Tim"); Console.WriteLine("Hashtable Key and Value pairs..."); foreach(DictionaryEntry entry in hash) { Console.WriteLine("{0} and {1} ", entry.Key, entry.Value); } Console.WriteLine("Is the Hashtable having fixed size? = "+hash.IsFixedSize); Console.WriteLine("If Hashtable read-only? = "+hash.IsReadOnly); Hashtable hash2 = Hashtable.Synchronized(hash); Console.WriteLine("Is Hash synchronized = "+hash2.IsSynchronized); } }
Output
This will produce the following output −
Hashtable Key and Value pairs... One and Katie Ten and Tim Five and Harry Three and Barry Seven and Tom Two and John Four and Eight and Andy Nine and I Six and F Is the Hashtable having fixed size? = False If Hashtable read-only? = False Is Hash synchronized = True
Example
Let us see another example −
using System; using System.Collections; public class Demo { public static void Main() { Hashtable hash = new Hashtable(); hash.Add("One", 1); hash.Add("Two", 2); hash.Add("Three", 2); hash.Add("Four", 4); hash.Add("Five",5); hash.Add("Six", 6); hash.Add("Seven", 7); Console.WriteLine("Hashtable Key and Value pairs..."); foreach(DictionaryEntry entry in hash) { Console.WriteLine("{0} and {1} ", entry.Key, entry.Value); } Console.WriteLine("Is the Hashtable having fixed size? = "+hash.IsFixedSize); Console.WriteLine("If Hashtable read-only? = "+hash.IsReadOnly); Console.WriteLine("Is Hash synchronized = "+hash.IsSynchronized); } }
Output
This will produce the following output −
Hashtable Key and Value pairs... One and 1 Five and 5 Three and 2 Seven and 7 Two and 2 Four and 4 Six and 6 Is the Hashtable having fixed size? = False If Hashtable read-only? = False Is Hash synchronized = False
