.NET錯誤：實現屬性必須有匹配的「只讀」或「只寫」符

Question

我越來越想實現在vb.net的接口時，這個錯誤：

Public Interface IFoo 
    ReadOnly Property Foo() As String 
End Interface 

Public Class myFoo 
    Implements IFoo 

    Public ReadOnly Property Foo() As String 
    Get 
     return "Foo" 
    End Get 
    End Property 
... 
End Class 

缺少什麼？

Answer 1

你將要告訴代碼的myFoo.Foo實現IFoo.Foo（注意添加Implements IFoo.Foo）：

Public Interface IFoo 
    ReadOnly Property Foo() As String 
End Interface 

Public Class myFoo 
    Implements IFoo 

    Public ReadOnly Property Foo() As String Implements IFoo.Foo 
     Get 
      Return "Foo" 
     End Get 
    End Property 
End Class 

據我所知，VB.NET不支持以同樣的方式隱式接口的實現像C＃一樣。
