C# | Dictionary.Count Property

Last Updated : 01 Feb, 2019

This property is used to get the number of key/value pairs contained in the Dictionary.

Syntax:

public int Count { get; }

Return Value : The number of key/value pairs contained in the Dictionary.

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  Dictionary 
using System; 
using System.Collections.Generic; 
  
class GFG { 
  
    // Driver code 
    public static void Main() 
    { 
  
        // Create a new dictionary of 
        // strings, with string keys. 
        Dictionary<string, string> myDict =  
           new Dictionary<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

Example 2:

// C# code to count the number of  
// key/value pairs in  Dictionary 
using System; 
using System.Collections.Generic; 
  
class GFG { 
  
    // Driver code 
    public static void Main() 
    { 
  
        // Create a new dictionary of  
        // strings, with string keys. 
        Dictionary<int, string> myDict =  
          new Dictionary<int, string>(); 
  
        // Adding key/value pairs in myDict 
        myDict.Add(1, "C"); 
        myDict.Add(2, "C++"); 
        myDict.Add(3, "Java"); 
        myDict.Add(4, "Python"); 
        myDict.Add(5, "C#"); 
        myDict.Add(6, "HTML"); 
  
        // To get count of key/value pairs in myDict 
        Console.WriteLine("Total key/value pairs"+ 
              " in myDict are : " + myDict.Count); 
    } 
}
