我有一个清单(Of AddlInfo),而AddlInfo是一个物体。

页: 1 参考另一个类别的功能:

Public Shared Sub SortAddlInfo(ByRef addlInfoList As List(Of AddlInfo))
    addlInfoList.Sort(AddressOf Comparer)
End Sub

Private Function Comparer(ByVal x As AddlInfo, ByVal y As AddlInfo) As Integer
    Dim result As Integer = x.AddlInfoType.CompareTo(y.AddlInfoType)
    Return result
End Function

如果我不把提及内容提上另一类,但当我试图这样做时,我有以下错误:

过重的解决失败是因为不能用这些论点来找准人:

 Public Sub Sort(comparison As System.Comparison(Of AddlInfo)) : Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
 Public Sub Sort(comparer As System.Collections.Generic.IComparer(Of AddlInfo)) :  AddressOf  expression cannot be converted to  System.Collections.Generic.IComparer(Of MyProject.AddlInfo)  because  System.Collections.Generic.IComparer(Of MyProject.AddlInfo)  is not a delegate type.

我可以把这些方法重新归入打电话的类别,但我想能够在我的申请范围内从不同类别中讲这些方法。

我也可以在方法上提出新的清单,但为什么? Seems silly。

如何解决这一问题? (我是否需要作更多的解释?)

提前感谢!
