C# SortedDictionary.Add() Method


The SortedDictionary.Add() method in C# is used to add an element with the specified key and value into the SortedDictionary<TKey, TValue>.

Syntax

The syntax is as follows −

public void Add (TKey key, TValue val);

Above, the value key is the key of the element to add, whereas val is the value of the element to add.

Example

Let us now see an example −

 Live Demo

using System;
using System.Collections;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      SortedDictionary<int, string> sortedDict = new SortedDictionary<int, string>();
      sortedDict.Add(100, "Mobile");
      sortedDict.Add(200, "Laptop");
      sortedDict.Add(300, "Desktop");
      sortedDict.Add(400, "Speakers");
      sortedDict.Add(500, "Headphone");
      sortedDict.Add(600, "Earphone");
      Console.WriteLine("SortedDictionary key-value pairs...");
      IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
   }
}

Output

This will produce the following output −

SortedDictionary key-value pairs...
Key = 100, Value = Mobile
Key = 200, Value = Laptop
Key = 300, Value = Desktop
Key = 400, Value = Speakers
Key = 500, Value = Headphone
Key = 600, Value = Earphone

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
using System.Collections.Generic;
public class Demo {
   public static void Main(){
      SortedDictionary<string, string> sortedDict = new SortedDictionary<string, string>();
      sortedDict.Add("A", "John");
      sortedDict.Add("B", "Andy");
      sortedDict.Add("C", "Tim");
      sortedDict.Add("D", "Ryan");
      sortedDict.Add("E", "Kevin");
      sortedDict.Add("F", "Katie");
      sortedDict.Add("G", "Brad");
      Console.WriteLine("SortedDictionary key-value pairs...");
      IDictionaryEnumerator demoEnum = sortedDict.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
      Console.WriteLine("\nThe SortedDictionary has the key F? = "+sortedDict.ContainsKey("F"));
   }
}

Output

This will produce the following output −

SortedDictionary key-value pairs...
Key = A, Value = John
Key = B, Value = Andy
Key = C, Value = Tim
Key = D, Value = Ryan
Key = E, Value = Kevin
Key = F, Value = Katie
Key = G, Value = Brad
The SortedDictionary has the key F? = True
