使用<Serializable()> 之后无法引用其属性与方法

新学VB.NET 看到一个对象克隆例子实际写完之后却发现无法进行属性引用
代码如下：
Cresume类

Imports System.IO
Imports System.Runtime.Serialization.Formatter
<Serializable()> Public Class Cresume

    '姓名
    Dim m_Name As String
    '地址
    Dim m_Address As String

    Public Property Address() As String
        Get
            Return m_Address
        End Get
        Set(ByVal value As String)
            m_Address = value
        End Set
    End Property
    Public Property Name() As String
        Get
            Return m_Name
        End Get
        Set(ByVal value As String)
            m_Name = value
        End Set
    End Property

    Public Function Clone() As Cresume
        Dim MS As New MemoryStream()
        Dim BF As New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter()
        BF.Serialize(MS, Me)
        MS.Position = 0
        Return (CType(BF.Deserialize(MS), Cresume))
    End Function

End Class

FORM页面中可以IMPORTS Cresume
之后Dim resume1 As New Cresume() 也不会有错误提示
但是下一步使用实例resume1时候提示错误declaration expected
