Question

I have a class which will wrap a dictionary to perform some operations on it. I am trying to instantiate it like:

class DescriptorList<K, Descriptor>
{
     <some code>
}

Descriptor is a class that I implemented but for some reason the compiler doesnt recognize that and thinks its a generic keyword (like ‘T’). How do I make the compiler recognize my type.

Answer 1

If you only want the key to be generic in your wrapping type, you don’t need a type descriptor in your class declaration for the value. You only need to specify the value type (Descriptor) when you’re declaring the Dictionary instance you’re wrapping. For example:

class DescriptorList<K>
{
   private Dictionary<K, Descriptor> wrapped = new Dictionary<K, Descriptor>() ;

   ...
}
