示例1: Example
' 导入命名空间
Imports System.Reflection
Public Module Example
' Mark OldProperty As Obsolete.
<ObsoleteAttribute("This property is obsolete. Use NewProperty instead.", False)>
Public ReadOnly Property OldProperty As String
Get
Return "The old property value."
End Get
End Property
Public ReadOnly Property NewProperty As String
Get
Return "The new property value."
End Get
End Property
' Mark OldMethod As Obsolete.
<ObsoleteAttribute("This method is obsolete. Call NewMethod instead.", True)>
Public Function OldMethod() As String
Return "You have called OldMethod."
End Function
Public Function NewMethod() As String
Return "You have called NewMethod."
End Function
Public Sub Main()
' Get all public members of this type.
Dim members() As MemberInfo = GetType(Example).GetMembers()
' Count total obsolete members.
Dim n As Integer = 0
' Try to get the ObsoleteAttribute for each public member.
Console.WriteLine("Obsolete members in the Example class:")
Console.WriteLine()
For Each member In members
Dim attribs() As ObsoleteAttribute = CType(member.GetCustomAttributes(GetType(ObsoleteAttribute),
False), ObsoleteAttribute())
If attribs.Length > 0 Then
Dim attrib As ObsoleteAttribute = attribs(0)
Console.WriteLine("Member Name: {0}.{1}", member.DeclaringType.FullName, member.Name)
Console.WriteLine(" Message: {0}", attrib.Message)
Console.WriteLine(" Warning/Error: {0}", if(attrib.IsError, "Error", "Warning"))
n += 1
End If
Next
If n = 0 Then
Console.WriteLine("The Example type has no obsolete attributes.")
End If
End Sub
End Module输出：
Obsolete members in the Example class: Member Name: Example.OldMethod Message: This method is obsolete. Call NewMethod instead. Warning/Error: Error Member Name: Example.OldProperty Message: This property is obsolete. Use NewProperty instead. Warning/Error: Warning
