Data Objects Implement An Interface IFillable?

All my data objects implement an interface IFillable

Public Interface IFillable
Sub Fill(ByVal Datareader As Data.IDataReader)
End Interface

In the objects themselves you will typically see something like

Public Class Supplier
Implements IFillable

[Code]...

Now here is the tricky bit. Given that all my property names WILL ALWAYS match my database column names what I want to do is using reflection generate the fill method at compile time and infer the types and column names for the datareader.I am assuming I will need to structure this functionality as some sort of a tool/vs plugin? What I am looking for is guidance on the best way to go about this.

PS: BTW: Obviously I could easily do this using reflection at runtime but I dont want to take the performance hit for it (Although theoretically if I could cache the values somehow (static class?) it might not be too bad).
