What do the question marks on that get.
What do they mean int? and ?? in this line of code, I have already found examples that used ? and ?? but never so many in a single line and this gets a little messy.
public int Something
{
get { return (this.parameters["Loading"] as int?) ?? 1; }
}

The question mark here int? means that its variable of the integer type accepts null values, while the ?? means that the return of (this.parameters["Loading"] as int?) be null, set the same with 1, is a condition if the return is null set the same with 1.

It means that if the value of
this.parameters["Loading"]
is null the return will be 1.
