Find Largest and Smallest numbers in C# app

Question

Hello all, I am working on a project for my school and I am really stumped. We have to create a console application where you are prompted to enter in 3 different numbers for the program. Well I need some help trying to get the program to find the smallest and the largest of those three numbers. Any suggestions? I've been told you need to compare number 1 to number, and then take that and compare it to number 3 but I don't know how. Can anyone help?
