if statement

[carstenht]

if i have the following array:

private string[] digits = { "0", "1", "2", "3", "4", "5", "6", "7", "8", "9" };

and i then want to check if a string contains any of these numbers, could i do something like this:

String test ="1+2+3";

if(test equals any of the digits in 'digits')
{
     // Do stuff
}
