“else if()” versus multiple “if()”s in C#

Question

How do these practically differ?

// Approach one
if (x == 1)
    DoSomething();
else if (x == 2)
    DoSomethingElse();

// Approach two
if (x == 1)
    DoSo         


        

Answer 1

No anwsers about performance?

So if x=1 then you do only one check in first case, and in second case you do 2 checks, so first case is faster.
