difference between the class / structure and the value / reference type?

hi could some1 plz explain a little more clearly how they are different and the like. msdn is a bit too confusing for me. thanks for the help

a class is an object of a structure is not, although you can add methods and events in a structure that prefer to use a class for complex objects with many methods and events and to inherit them. pass a variable ByRef ByVal and (I think this Mena) which passes the value of a variable or pointer of it, the default method is ByVal yu is not necessary to specify. As you pass a variable to a function or method ByRef routine is passed the pointer to it and if that routine changes the value of the variable passed, will become the new value of the variable, here is an example Sub Main () (Int age = 0; if (GetAge ("John", age)) (/ / Do something)) GetAge private bool (string name, int age) (/ / Some code to find the name in a variable or something DB / / if the record is the code will run ie age = (Int32) dtt.Rows [i]. ItemArray [5]; return true;) in this example the function is of type boolean, and assess if it is true, so if it is true, the Commission will check the value of the parameter of age. To make it simple to use the equivalent of ByRef (out) when it takes more than a return to a routine, I create a route to find a product ID who wants to know if the ID exists and then complete a structure or a class with the data you need, so go to a function of the ID you are looking for and the empty structure / Class of valuation and if the ID is the class / structure is full of data and the routine returns true else return false. Return false if you do not need to audit data returned but if it is true that you do.

    The AI chain of schools doesn't have a good rep in the industry. FIDM, which is big and popular, also has a poor rep. The best fashion design program in CA is at Otis College of Art, in Los Angeles.

    Hey guys, I could really use some help. I adapted an old website template that I have used before, to make a site for a friend. I am not a professional, so my coding isn’t great, but I managed to put a site together that works well with firefox, chrome, and every other browser I have tried…

    BBC America would be a good one as well. They blatantly tell it like it is. The GOP would hate it.
