C# | Count the number of key/value pairs in HybridDictionary
HybridDictionary.Count property is used to get the number of key/value pairs contained in the HybridDictionary.
Syntax:
public int Count { get; }
Return Value: The number of key/value pairs contained in the HybridDictionary.
Note: Retrieving the value of this property is an O(1) operation.
Below programs illustrate the use of HybridDictionary.Count property:
Example 1:
// C# code to get the number of key/value // pairs contained in the HybridDictionary. using System; using System.Collections; using System.Collections.Specialized; class GFG { // Driver code public static void Main() { // Creating a HybridDictionary named myDict HybridDictionary myDict = new HybridDictionary(); // 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 get the number of key/value // pairs contained in the HybridDictionary. using System; using System.Collections; using System.Collections.Specialized; class GFG { // Driver code public static void Main() { // Creating a HybridDictionary named myDict HybridDictionary myDict = new HybridDictionary(); // Adding key/value pairs in myDict myDict.Add( "I" , "first" ); myDict.Add( "II" , "second" ); myDict.Add( "III" , "third" ); myDict.Add( "IV" , "fourth" ); myDict.Add( "V" , "fifth" ); // To get count of key/value pairs in myDict Console.WriteLine( "Total key/value pairs in myDict are : " + myDict.Count); } } |
