Get or set the value associated with the specified key in StringDictionary in C#

To get or set the value associated with specified key in StringDictionary, the code is as follows −

Example

 Live Demo

using System;
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("Value associated with key D = "+strDict["D"]);
      Console.WriteLine("Value associated with key F = "+strDict["F"]);
   }
}

Output

This will produce the following output −

Value associated with key D = Pet Supplies
Value associated with key F = Footwear

Example

Let us see another example −

 Live Demo

using System;
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("Value associated with key D = "+strDict["D"]);
      Console.WriteLine("Value associated with key F = "+strDict["F"]);
      strDict["F"] = "HDD";
      Console.WriteLine("Value associated with key F (UPDATED) = "+strDict["F"]);
   }
}

Output

This will produce the following output −

Value associated with key D = Pet Supplies
Value associated with key F = Footwear
Value associated with key F (UPDATED) = HDD
