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: csharp
// 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 : 6Example 2: csharp
// 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);
}
}
Output:
Total key/value pairs in myDict are : 6Note:
Retrieving the value of this property is an O(1) operation.
