示例1: Demo
' 导入命名空间
Imports System.Reflection
Public Class Demo
' Declare three fields.
' The first field is private.
Private m_field As String = "String A"
'The second field is public.
Public Field As String = "String B"
' The third field is public and const, hence also static
' and literal with a default value.
Public Const FieldC As String = "String C"
End Class
Module Module1
Sub Main()
' Create an instance of the Demo class.
Dim d As New Demo()
Console.WriteLine(vbCrLf & "Reflection.FieldAttributes")
' Get a Type object for Demo, and a FieldInfo for each of
' the three fields. Use the FieldInfo to display field
' name, value for the Demo object in d, and attributes.
'
Dim myType As Type = GetType(Demo)
Dim fiPrivate As FieldInfo = myType.GetField("m_field", _
BindingFlags.NonPublic Or BindingFlags.Instance)
DisplayField(d, fiPrivate)
Dim fiPublic As FieldInfo = myType.GetField("Field", _
BindingFlags.Public Or BindingFlags.Instance)
DisplayField(d, fiPublic)
Dim fiConstant As FieldInfo = myType.GetField("FieldC", _
BindingFlags.Public Or BindingFlags.Static)
DisplayField(d, fiConstant)
End Sub
Sub DisplayField(ByVal obj As Object, ByVal f As FieldInfo)
' Display the field name, value, and attributes.
'
Console.WriteLine("{0} = ""{1}""; attributes: {2}", _
f.Name, f.GetValue(obj), f.Attributes)
End Sub
End Module输出：
m_field = "String A"; attributes: Private Field = "String B"; attributes: Public FieldC = "String C"; attributes: Public, Static, Literal, HasDefault
示例2:
Dim fi As FieldInfo = obj.GetType().GetField("field1")
If (fi.Attributes And FieldAttributes.FieldAccessMask) = _
FieldAttributes.Public Then
Console.WriteLine("{0:s} is public. Value: {1:d}", fi.Name, fi.GetValue(obj))
End If
