Checking if a string array contains a value, and if so, getting its position

I have this string array:

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

I would like to determine if stringArray contains value. If so, I want to locate its position in the array.

I don’t want to use loops. Can anyone suggest how I might do this?
