I couldnt agree with you more on this point. But there are cases when from you non-generic class, you want to call a generic method and all you want do is to pass the "current type" and not any other type. In most cases, you will hard-code the class name, but if you're working in the base class, you would not know the type of the deriving class.

The only workaround for this limiation, is to make the method from your base class abstract and let the deriving classes implement the call.

protected List<List<List<Bitmap>>> v_Maps_MASTER = new List<List<List<Bitmap>>>( );

protected List<Bitmap> v_Maps_Button_UP = new List<Bitmap>( );

if ( ( enumContours.TopAndBottom == f_Contours ) || ( enumContours.TopOnly == f_Contours ) )
     {
     v_Maps_UP[ i_Btn_BL_BR ][ i_NF ].SetPixel( 0, 0,
          Color_IncOrDecLum( v_cBaseUP_Glossed, lumDiffAccumulated_I + f_LumDif_EdgeBevels ) );
     }
else
     {
     v_Maps_UP[ i_Btn_BL_BR ][ i_NF ].SetPixel( 0, 0,
          Color_IncOrDecLum( v_cFLATFILL_UPContours, lumDiffAccumulated_I + f_LumDif_EdgeBevels ) );
     }
