Question

I need another (dozen) pair of eyes on this. The following code:

Interface iRuleEntity     Function GetRuleViolations() As List(Of RuleViolation) End Interface  Partial Public Class Feedback     Implements iRuleEntity      Public Function GetRuleViolations() As List(Of RuleViolation)         Return Nothing     End Function  End Class 

is giving me this error:

'Feedback' must implement 'Function GetRuleViolations() As System.Collections.Generic.List(Of RuleViolation)' for interface 'iRuleEntity'. 

What am I missing?

Answer 1

You haven’t said that GetRuleViolations implements iRuleEntity.GetRuleViolations. It’s not implicit like it is in C#.

From the docs for Implements:

You use the Implements statement to specify that a class or structure implements one or more interfaces, and then for each member you use the Implements keyword to specify which interface and which member it implements.

So:

Partial Public Class Feedback     Implements iRuleEntity      Public Function GetRuleViolations() As List(Of RuleViolation) _     Implements iRuleEntity.GetRuleViolations         Return Nothing     End Function  End Class 

(Note the line continuation on the first line of the function.)
