Value equal to ANY value in an array?

just wondering if there is any way of checking if Value A is equal to ANY value within an array (without using large loop functions) - sort of like a "Where" function.

e.g.

if (DataRow[column1value] == <any value within>Array A[])
{
//do...
}

Cheers!

You can try Array.Contains

EDIT.

Im sorry, thisis what i meant

int[] array = new int[] { 1, 2, 3, 4, 5 };
if (array.Contains(5))
{
}

If we're talking about pure Array type, there's IndexOf() method that will help you determine whether there's a value in it

In .NET 3.5 or higher, using LINQ:

bool found = yourArray.Contains(yourValue);

In earlier versions of the framework:

bool found = Array.IndexOf(yourArray, yourValue) > -1;
