Question

I’m injecting my dependencies into my classes fine, but I’m wondering if it’s possible to get the class name I’m injecting into?

For example:

Bind<ISomething>.ToMethod(c => new Something([GIVE INJECTING *TO* CLASS NAME]));

So, if I had:

public class Blah{
  public Blah(ISomething something) { /**/ }
}

When injecting Ninject would in effect call:

new Blah(new Something("Blah"));

Can this be done?

Yes, it can be done. You use the IContext you’re given in the ToMethod method to get the name of the type you’re being injected into like this:

Bind<ISomething>().ToMethod(c => new Something(GetParentTypeName(c)));

Which uses this little helper method (which could also be turned into a nice extension method):

private string GetParentTypeName(IContext context)
{
    return context.Request.ParentRequest.ParentRequest.Target.Member.DeclaringType.Name;
}
