How to check if Specified Element is present in the Array in C# ?

Answer

To check if a specified element is present in an array in C#, you can use methods like Contains.

✐ Examples

1 Check if Element 30 is present in Integer Array using Contains

In this example,

We create an integer array named numbers with values 10, 20, 30, 40, 50.
We use the Contains method to check if element 30 is present in the array.
The Contains method returns true if the element is found, otherwise false.

C# Program

using System;
class Program
{
    static void Main()
    {
        int[] numbers = { 10, 20, 30, 40, 50 };
        bool isPresent = Array.IndexOf(numbers, 30) != -1;
        Console.WriteLine("Element 30 is present: " + isPresent);
    }
}

Output

Element 30 is present: True

2 Check if Element 'banana' is present in String Array using Contains

In this example,

We create a string array named fruits with values 'apple', 'banana', 'cherry'.
We use the Contains method to check if element 'banana' is present in the array.
The Contains method returns true if the element is found, otherwise false.

C# Program

using System;
class Program
{
    static void Main()
    {
        string[] fruits = { "apple", "banana", "cherry" };
        bool isPresent = Array.IndexOf(fruits, "banana") != -1;
        Console.WriteLine("Element 'banana' is present: " + isPresent);
    }
}

Output

Element 'banana' is present: True
