I have a Business & Presentation Layer. I am trying to access a method in the Business Layer from the Presentation Layer.
// Presentation Layer Code
Grade grd = new Grade();
grd = Businesslayer.GetGradeID((int)gradeId);

Grade is a Class & GetGradeID is the method in the BusinessLayer.

Error I am getting is <<Cannot Implicitly convert type BusinessLayer.Grade to PresentationLayer.Grade>>

Any help please.

Do I am right to say that from your Businesslayer you are retrieving
this list of Grade?
If I am right the Declaration on Presentation Layer should be:

var  grd = Businesslayer.GetGradeID((int)gradeId);

grd example contents List of Grade

Hope this could help...

Hi Algem.

You understood me correctly. However, im using c# with a normal desktop application so i changed the var to an Object and worked perfectly fine.
