RE: [DotGNU]How do you simulate an inner class in C#?

[Thong \(Tum\) Nguyen]

Hi Mohan,

A java inner class is simply a class that has a reference to the parent
class.  You just need to pass a reference to the 'outer' class to the
'inner' class's constructor and store it somewhere.

Here's an example:

Java code:

public class Outer
{
   int x;

   public class Inner
   {
       public void Foo()
       {
           x = 10;
       }
   }
}

The java compiler generates something like this:

public class Outer
{
}

public class Outer$Inner
{
   private Outer parent;

   public class Outer$Inner(Outer parent)
   {
      this.parent = parent;
   }

   public void Foo()
   {
       this.parent.x = 10;
   }
}

In C# you could do this:

public class Outer
{
   public class Inner
   {
      private Outer parent;

      public Inner(Outer parent)
      {
          this.parent = outer;
      }

      public void Foo()
      {
          this.parent.x = 10;
      }
   }
}

Delegates aren't needed :)
