Add Key and Value into StringDictionary in C#

To add key and value into 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", "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);
      }
   }
}

Output

This will produce the following output −

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

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("1", "Electric Cars");
      strDict.Add("2", "SUV");
      strDict.Add("3", "AUV");
      Console.WriteLine("StringDictionary elements...");
      foreach(DictionaryEntry de in strDict) {
         Console.WriteLine(de.Key + " " + de.Value);
      }
   }
}

Output

This will produce the following output −

StringDictionary elements...
1 Electric Cars
2 SUV
3 AUV
