Check if element is contained in an array

Question

I have the following code, in which I want to verify if the the string called value matches an element contained in stringArray.

 string[] stringArray = { "text1", "text2", "text3", "text4" };

        string value = "text1";

        if ( /* ______________ */) // if value exists in stringArray
            Console.WriteLine("True");
        else
            Console.WriteLine("False");

Is there a method I could use to execute this?

Enumerable.Contains will do the work:

using System.Linq;

if (stringArray.Contains("text1")) 
{
    Console.WriteLine("True");
}

Btw this needs Linq referenced and `using System.Linq;` in the code. – vesan Jun 19 '14 at 23:11

I believe the following will work:

string[] stringArray = {"text 1", "text 2"};
string value = "text 1";
Console.WriteLine(stringArray.Any(str => str.Equals(value)) ? "True" : "False");
