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:

csharp

// 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:

csharp

// 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);
    }
}
