C# if statement [on hold]

I am creating a program in C# where roll 2 dice 100 times. I got that part but am suck on " Whenever the two dice display the same number, the program should show the roll sequence number (e.g. the 10th roll) and the number on the dice (e.g. both dice throw 6)." Do I use the if match statement? and if so how. Thanks
