c# 4.0 - C# difference between else if and if

Question

What is the difference between if and else if in C#? For example if i write

if (x==5){
    do something
}

And

else if (x==5){
    do something
}

Are they totally same… so ? What is the difference?

Answer 1

**IF** you are confused
 read the c# spec
**ELSE IF** you are kind of confused
 read some books
**ELSE**
 everything should be OK.

Jokes are apart, usually an if statement follows this sort of structure:

if (condition)
{
    // executed only if "condition" is true
}
else if (other condition)
{
    // executed only if "condition" was false and "other condition" is true
}
else
{
    // executed only if both "condition" and "other condition" were false
}

The if portion is the only block that is absolutely mandatory. else if allows you to say "ok, if the previous condition was not true, then if this condition is true...". The else says "if none of the conditions above were true..."

You can have multiple else if blocks, but only one if block and only one (or zero) else blocks.
