stupid question

Joe Doe

I have been learning the C# language over the last month or two from the book Visual C# 2008 and was wondering what is the "this" keyword used for. I see it coming up over and over again in the book but it doesn't seem that they give a good definition of what it is used for.

ok the keyword this is used by a given object "class" to refer it self
example:
public class Person
{
     /* The constructor the first method lunched after the object creation unsing new keyword */
    public person(string FirstName, string LastName)
    {
         //The this here is used to refer the object it self, as you know
         //the object person has a field called _FirstName and _LastName
         this._FirstName;
         this._LastName;
     }
     public string _FirstName;
     public string _LastName;
}

in the other hand
Person me = new Person("Bejaoui","Bechir");
will define an object Person, in fact when me is created it invokes the Person(FirstName,LastName) then this or in this case me._FirstName<-FirstName
me._LastName<-LastName
