I am trying to simulate a Dlookup function in MS Access where I want to retrieve just one column from
a record in an Access database. There are three errors. I have checked but everything looks normal to me.
Error CS1503 Argument 1: cannot convert from 'string' to 'Prop_Name' Line 25
Error CS0246 The type or namespace name 'Prop_Name' could not be found
(are you missing a using directive or an assembly reference?) Line 34
Error CS1001 Identifier expected Line 34
