I've inherited some code at work that has a really bad smell. I'm hoping to find the most painless solution possible.

Is there a way to check if some arbitrary number is a valid element in an array?

Example - I need to check if array[25] exists.

Preferably I would prefer to do this without doing a foreach() through the array to found the rows.

Is there any way to do this, or am I stuck with foreach loop?

Test the length

int index = 25;
if(index < array.Length)
{
    //it exists
}
