multidimensional array if statement problem

hi all basically i have to randomise an array of playing cards(with 4 suits) so i get two random numbers within my ranges and i need to see if both array values are same as the random numbers

here is my code

if (shuffledcardsuit[x, y] == FNum, SNum)

im trying to do an if statement for basically if the x element is the same as FNum and then the y element same as SNum

i have skipped this and made a normal array and made the game without the suits but now i got the game working how i want it i have come back to add in the suits of cards and im only seeing a possible way of doing this by having multidimensional array [0-8, 0-3] where the second set of values are for example
0=red square
1= red circle
2=black square
3=black circle
