Limiting Results In Crystal Reports

I have a report that displays a lot of information. I only want to show a certain data that is related to a specific "student ID". We are writing this program in C#. We are using the Crystal Report packaged with Visual Studio. Can we pass a variable from the program to crystal?

Thanks for any help,
