In c#, how to implement functions like c++ macro define?

Question

Macro define very funny and flexible in c++，it makes code very very concise and simple.

But in c#,there are only macro declarations,unable to use macro flexible like c++.

Maybe attribute in c# can do something like macro in c++，but I don't be familiar with it.

From c++ to c#,can't use macro，I feel like lost something......

so......how to use something in c# like macro in
c++?
