Do else if statements exist in C#?

Question

I have come across the following code in C#.

if(condition0) statement0;
else if(condition1) statement1;
else if(condition2) statement2;
else if(condition3) state         


        

Answer 1

It's a multi-layered if-else.

The reason it is has to do with c# syntax rules. An else is followed by a statement, and any if chain qualifies as a statement.

Answer 2

To expand on @hunter's answer the reason, as you hit on it that without brackets it will only execute the next line, if it were a bunch of nested the else would need brackets:

if(condition0) 
  statement0;
else
{
  if(condition1)
    statement1;
  else
  {
    if(condition2)
      statement2;
    else
    {
      if(condition3)
        statement3;
      else
      ...
    }
  }
}
