How do I create a class that inherits from another and passes a type parameter in CodeDom?

Question

Here's what I want the resulting class declaration to look like:

public sealed partial class Refund : DataObjectBase<Refund>
 {
}

}

This code (snipped):

targetClass = new CodeTypeDeclaration(className);
            targetClass.IsClass = true;
            targetClass.TypeAttributes =
                TypeAttributes.Public | TypeAttributes.Sealed;
            targetClass.IsPartial = true; //partial so that genn'ed code can be safely modified
            targetClass.TypeParameters.Add(new CodeTypeParameter{ Name=className});
            targetClass.BaseTypes.Add(new CodeTypeReference { BaseType = "DataObjectBase", Options = CodeTypeReferenceOptions.GenericTypeParameter });

Produces this class declaration:

public sealed partial class Refund<Refund> : DataObjectBase
 {
}

What am I doing wrong?

Answer 1

I think that the following string for the BaseType should do the trick (untested):

"DataObjectBase`1[[Refund]]"

It may be possible that you need to provide a fully-qualified name for Refund, at leat including the assembly name:

"DataObjectBase`1[[Refund, RefundAssembly]]"

And you should then remove the line targetClass.TypeParameters.Add(...).

Answer 2

If you use Expressions to CodeDOM it could be

var cls = Define.Class("Refund", 
   TypeAttributes.Public | TypeAttributes.Sealed, true)
   .Inherits(CodeDom.TypeRef("DataObjectBase","Refund"))
