Check if a value is in array in C#

To check if a value is in array in C# you can use the method Contains().

Remember to include namespaces required: using System.Linq;

Example

using System;
using System.Linq;

public class Program
{
	public static void Main()
	{
		string[] fruits = {"Banana", "Orange", "Apple"};

		if(fruits.Contains("Pineapple"))
		{
			
		}else{
			Console.WriteLine("Does not exist in Array");
		}

		if(fruits.Contains("Banana"))
		{
			Console.WriteLine("Exist in Array");
		}	
	}
}

Output
