C# return query

I have noticed the use of this code in an application that I am developing can anybody tell me what it means when you have the ? and :

ie return (returnValue == 0 ? true : false);

Does it act like an if else statement??

Many thanks

This is an abbreviated conditional syntax. The expression preceding the question mark is evaluated. If it is true, the expression preceding the colon is returned. Otherwise, the expression following the colon is returned. In other words,

return (returnValue == 0 ? true : false)

is the same as

if (returnValue == 0) {
    return true;
} else {
    return false;
}

Incidentally, this expression is mildly redundant, especially considering that this abbreviated syntax slightly reduces the codes readability. Even though I would consider the 'if/else' to be the preferred syntax, since it is easier to read, an equivalent shorthand expression would be:

return (returnValue == 0);

which would return true or false, depending on the value of returnValue.

Cheers,
Randall
