What's new in C# 3.0 ? Part 3

assume you want to make a fly variable(which i will use it once in my code) of complex type, all what i have to do is go to the solution explorer and add a new class for this type, by this way if i want to make 10 new types i will make 10 different class, but this is not the best solution so C# 3.0 came with the the best solution with the Anonymous Type.

now i don't have to write a class foreach type i wanna use, the compiler will do this for my :)
eg .. i want to make a new type which will hold my firstname , lastname and my age
it will be like this :-
var UserData = new {Fisrtname = "Mohamed", LastName = "Gamal" , age = 19 };

in the compilation time the compiler will generate a temp class for this type , the Members of this class is a Read\Write properties which inferred from the Object initializer (i will speak about it in another post isA ).
back to our example .. here the compiler will make 3 properties in this class, 2 of type string and the third of type int, the compiler can do this job during the compilation time depending on the initialization value.

by this way i don't have to generate classes for fly variables and this increases the code readability and save many lines of code to be written.

That’s it.
