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);
}
} |
Output:
Total key/value pairs in myDict are : 5
