看不到"必须执行"错误

Question

我需要另外一双(十几只)眼睛.以下代码:

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

给我这个错误:

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

我错过了什么？

Answer 1

你没有说过那个GetRuleViolations工具iRuleEntity.GetRuleViolations.它并不像C#中那样隐含.

来自以下文档Implements:

您可以使用Implements语句指定类或结构实现一个或多个接口,然后为每个成员使用Implements关键字指定哪个接口及其实现的成员.

所以:

Partial Public Class Feedback
    Implements iRuleEntity

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

End Class

(注意函数第一行的续行.)
