C# | SortedDictionary.Count Property

Last Updated : 31 Jan, 2019

This property is used to get the number of key/value pairs contained in the SortedDictionary<TKey, TValue>.

Syntax:

  public int Count { get; }

Return Value : It returns the number of key/value pairs contained in the SortedDictionary.

Below are the programs to illustrate the use of above-discussed property:

Example 1:

   // C# code to count the number of 
// key/value pairs in SortedDictionary 
using System; 
using System.Collections.Generic; 
  
class GFG { 
  
    // Driver code 
    public static void Main() 
    { 
  
        // Create a new SortedDictionary of 
        // int, with int keys. 
        SortedDictionary<int, int> myDict =  
           new SortedDictionary<int, int>(); 
  
        // Adding key/value pairs in myDict 
        myDict.Add(9, 8); 
        myDict.Add(3, 4); 
        myDict.Add(4, 7); 
        myDict.Add(1, 7); 
  
        // To get count of key/value pairs in myDict 
        Console.WriteLine("Total key/value pairs "
              + "in myDict are : " + myDict.Count); 
    } 
} 
 
  

Output:

  Total key/value pairs in myDict are : 4

Example 2:

   // C# code to count the number of 
// key/value pairs in  SortedDictionary 
using System; 
using System.Collections.Generic; 
  
class GFG { 
  
    // Driver code 
    public static void Main() 
    { 
  
        // Create a new dictionary of 
        // strings, with string keys. 
        SortedDictionary<string, string> myDict =  
          new SortedDictionary<string, string>(); 
  
        // Adding key/value pairs in myDict 
        myDict.Add("Australia", "Canberra"); 
        myDict.Add("Belgium", "Brussels"); 
        myDict.Add("Netherlands", "Amsterdam"); 
        myDict.Add("China", "Beijing"); 
        myDict.Add("Russia", "Moscow"); 
        myDict.Add("India", "New Delhi"); 
  
        // To get count of key/value pairs in myDict 
        Console.WriteLine("Total key/value pairs "
              + "in myDict are : " + myDict.Count); 
    } 
} 
 
  

Output:

  Total key/value pairs in myDict are : 6
