This code snippet shows how to remove a specified element from an array in C# using multiple ways i.e., using Array.FindAll method, Using Enumerable.Where Method.

Using Array.FindAll Method:

using System;
using System.Linq;
 
public class RemoveElement
{
    public static void Main()
    {
        // Array
        int[] array = { 100, 200, 300, 400, 500, 600 };
        // Item to be removed from an array
        int itemToRemove = 300;
        // Find and remove a specified item/element from an arry
        array = Array.FindAll(array, i => i != itemToRemove).ToArray();
        // Iterate an array and print
        foreach(var item in array)
        {
            Console.WriteLine(item);
        }
        Console.ReadKey();
    }
}

Output:

100
200
400
500
600

Using Enumerable.Where Method:

using System;
using System.Linq;
 
public class RemoveElement
{
    public static void Main()
    {
        // Array
        int[] array = { 100, 200, 300, 400, 500, 600 };
        // Item to be removed from an array
        int itemToRemove = 300;
        // Find and remove a specified item/element from an arry using "Where"
        array = array.Where(i => i != itemToRemove).ToArray();
        // Iterate an array and print
        foreach(var item in array)
        {
            Console.WriteLine(item);
        }
        Console.ReadKey();
    }
}

 Output:

100
200
400
500
600
