C++ Friendship in C#

[Mike Gleason jr Couturier]

Hi,

I would like class B to access private members of class A
for optimisation reasons... To be specific. B instanciates A
and should initializes A's members to some values. But the public
interface of A shouldn't expose A's member variables.

Is there a way to do this in C#?

I've already done this in C++!

Thanks!

Mike

Hello Mike Gleason jr Couturier,

Look at [assembly: InternalsVisibleTo("MyFriendAssembly")]
it just give visibility to your assembly

Ok but I'm doing web development, I guess that my classes
would be in the same assembly!?

Thanks for your prompt reply!

Hello Mike Gleason jr Couturier,

Then use internal or internal protected type visibility

Hi Mike,

In C# you can't have friendship like relations between classes. What you can
do, is to use internal access modifier(instead of public) and then all the
classes that reside in the same assembly will have access to those members
as if they were declared public, and classes that are in other assemblies
will not see those members (as if they were declared private). If you want
to extend this internal behaviour to another assembly, then you can use the
InternalsVisibleToAttribute
(http://msdn2.microsoft.com/en-us/library/0tke9fxk(VS.80).aspx). So by using
this attribute, you don't need to have your classes in the same assembly.
