How to count the Number of Occurrences of Specified Element in the Array in C# ?

Answer

To count the number of occurrences of a specified element in an array in C#, you can use LINQ queries or loops to iterate through the array and count each occurrence.

✐ Examples

1 Count Occurrences of Element 30 in Integer Array using LINQ

In this example,

We create an integer array named numbers with values 10, 20, 30, 40, 30, 50.
We use LINQ query syntax with the where clause to filter elements equal to 30.
We count the filtered elements using the Count method of LINQ.
The count will represent the number of occurrences of element 30.

C# Program

using System;
using System.Linq;
class Program
{
    static void Main()
    {
        int[] numbers = { 10, 20, 30, 40, 30, 50 };
        int count = numbers.Where(num => num == 30).Count();
        Console.WriteLine($"Number of occurrences of element 30: {count}");
    }
}

Output

Number of occurrences of element 30: 2

2 Count Occurrences of Element 'banana' in String Array using loop

In this example,

We create a string array named fruits with values 'apple', 'banana', 'cherry', 'banana'.
We initialize a counter variable count to 0 to store the count of occurrences.
We use a loop to iterate through the array and increment count each time element 'banana' is found.
After the loop, count will contain the total count of occurrences of element 'banana'.

C# Program

using System;
class Program
{
    static void Main()
    {
        string[] fruits = { "apple", "banana", "cherry", "banana" };
        int count = 0;
        foreach (string fruit in fruits)
        {
            if (fruit == "banana")
            {
                count++;
            }
        }
        Console.WriteLine($"Number of occurrences of element 'banana': {count}");
    }
}

Output

Number of occurrences of element 'banana': 2
