How to get Synchronize access to the StringDictionary in C#

CsharpServer Side ProgrammingProgramming

To get synchronize access to the StringDictionary, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main(){
      StringDictionary strDict = new StringDictionary ();
      strDict.Add("A", "Books");
      strDict.Add("B", "Electronics");
      strDict.Add("C", "Appliances");
      strDict.Add("D", "Pet Supplies");
      strDict.Add("E", "Clothing");
      strDict.Add("F", "Footwear");
      Console.WriteLine("StringDictionary key-value pairs...");
      foreach(DictionaryEntry de in strDict) {
         Console.WriteLine(de.Key + " " + de.Value);
      }
      Console.WriteLine("Value associated with key D = "+strDict["D"]);
      Console.WriteLine("Value associated with key F = "+strDict["F"]);
      Console.WriteLine("\nSynchronize access..");
      lock(strDict.SyncRoot) {
         foreach(DictionaryEntry de in strDict) {
            Console.WriteLine(de.Key + " " + de.Value);
         }
      }
   }
}

Output

This will produce the following output −

StringDictionary key-value pairs...
a Books
b Electronics
c Appliances
d Pet Supplies
e Clothing
f Footwear
Value associated with key D = Pet Supplies
Value associated with key F = Footwear
Synchronize access..
a Books
b Electronics
c Appliances
d Pet Supplies
e Clothing
f Footwear

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      StringDictionary strDict = new StringDictionary();
      strDict.Add("A", "John");
      strDict.Add("B", "Andy");
      strDict.Add("C", "Tim");
      strDict.Add("D", "Ryan");
      strDict.Add("E", "Kevin");
      strDict.Add("F", "Katie");
      strDict.Add("G", "Brad");
      Console.WriteLine("StringDictionary elements...");
      foreach(DictionaryEntry de in strDict) {
         Console.WriteLine(de.Key + " " + de.Value);
      }
      Console.WriteLine("\nSynchronize access..");
      lock(strDict.SyncRoot) {
         foreach(DictionaryEntry de in strDict) {
            Console.WriteLine(de.Key + " " + de.Value);
         }
      }
   }
}

Output

This will produce the following output −

StringDictionary elements...
a John
b Andy
c Tim
d Ryan
e Kevin
f Katie
g Brad

Synchronize access..
a John
b Andy
c Tim
d Ryan
e Kevin
f Katie
g Brad
