How to check if a Specific Element is present in the List in C# ?

Answer

To check if a specific element is present in a list in C#, you can use the Contains method of the List class.

✐ Examples

1 Check Element Presence in List (Integer)

In this example,

We create a list named myList with some elements.
We use the Contains method to check if the specified element is present in the list.
The Contains method returns true if the element is present, otherwise false.
Finally, we print the result to standard output.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<int> myList = new List<int> { 10, 20, 30, 40, 50 };
        int searchElement = 40;
        bool isPresent = myList.Contains(searchElement);
        Console.WriteLine("Element presence in list: " + isPresent);
    }
}

Output

Element presence in list: True

2 Check Element Presence in List (String)

In this example,

We create a list named myList with some string elements.
We use the Contains method to check if the specified string is present in the list.
The Contains method returns true if the string is present, otherwise false.
Finally, we print the result to standard output.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<string> myList = new List<string> { "apple", "banana", "cherry", "date", "elderberry" };
        string searchElement = "cherry";
        bool isPresent = myList.Contains(searchElement);
        Console.WriteLine("Element presence in list: " + isPresent);
    }
}

Output

Element presence in list: True
