Here is the code,
There is a compiler error "ConsoleApplication1.A.B' is inaccessible due to its protection level". Why? I thought by default, A.B is internal. So it should be able to be accessed by function Main.Code:namespace ConsoleApplication1
{
class A
{
public A()
{
}
class B
{
public B()
{
A a = new A();
}
};
};
class Program
{
static void Main(string[] args)
{
A.B b = new A.B();
}
}
}
Pl make class b public ..
Do paste the errors on Google search , many times you will
immediately get answer.
I believe by default classes are private. If you are interested in this, why not write some code that uses reflection to tell you exactly what's going on? With reflection you can access all the attributes of the class including it's protection level.Quote:

that time , I felt , if I am using Public key word then what is use of property Data Abstraction / Hiding ....
In case of MFC the things are completely different
By default classes are internal. Actually you can't define a class as private. Class must be either public or internal. But since class Ｂ is defined within class A, so class B might be private. I am kind of new to C#. Would you tell me how to use reflection to tell whether B is private or public? Thanks.Quote:
