“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

When you use multiple else if, it will execute the condition that meets. If there are remaining cases, they will be skipped. When you have multiple if, it will check every statement. So this becomes more of a performance issue.
