Delphi Compiler Error
E2060 Class and interface types only allowed in type section
Reason for the Error & Solution
Class or interface types must always be declared with an explicit type declaration in a type section. Unlike record types, they cannot be anonymous.
The main reason for this is that there would be no way you could declare the methods of that type (since there is no type name).
Incorrect (attempting to declare a class type within a variable declaration):
program Produce;
var
MyClass : class
Field: Integer;
end;
begin
end.
Correct:
program Solve;
type
TMyClass = class
Field: Integer;
end;
var
MyClass : TMyClass;
begin
end.
