Changing cell source

Simple one (I'm sure) for you on here. I have a formula, =IF(C2=1,D2*C5+E2*E5,0) that's works just fine if C2=1. Is it possible to have a single formula that would work if C2 was to equal 2,3 or 4?

Basically if I could I would have 4 formulas in the same cell they would be =IF(C2=1,D2*C5+E2*E5,0) =IF(C2=2,D2*C6+E2*E6,0) =IF(C2=3,D2*C7+E2*E7,0) =IF(C2=4,D2*C8+E2*E8,0)

Thanking you in anticipation
