Ternary ? operator vs the conventional If-else operator in c# [duplicate]

Answer 1

No.

Use what makes your code readable. If if statements do that, use them. If ternary operators do that, use them.

It is likely that both will compile down to the same IL anyway.

In any event the things that will slow down your application will likely be the database or the network or the hard drive ... anything except whether you used if statements or ternary expressions.
