关于VB类的一个问题 [英] A Question on VB Classes

有人可以告诉我，我做错了什么。我正在尝试创建名为Dog的

Wolf.age ....这是为什么？
公共类Form1
公共类DOG
Dim COLOR As String
Dim AGE As Integer
Dim NAME As String
End Class
Public Sub Button1_Click（ByVal sender As System.Object，ByVal e As
System.EventArgs）处理Button1.Click
DIM WOLF作为新狗
WOLF.AGE = 10
结束次级
结束班级
问候Brian

推荐答案
公开Class Form1
Public Class Form1
Public Class DOG
Dim COLOR As String
Dim AGE As Integer
DIM NAME为字符串
结束类
Public Sub Button1_Click（ByVal sender As System.Object，ByVal e As
System.EventArgs）手les Button1.Click
DIM WOLF As New DOG
WOLF.AGE = 10
End Sub
结束班
问候Brian
Public Class DOG
Dim COLOUR As String
Dim AGE As Integer
Dim NAME As String
End Class
Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim WOLF As New DOG
WOLF.AGE = 10
End Sub
End Class

你的昏暗默认情况下不公开，请尝试相反：
公共颜色字符串
公共年龄为整数
公共名称As String
Your "Dim" isn''t public by default, try this instead:
Public COLOUR As String
Public AGE As Integer
Public NAME As String
因为属性变量不可见。使用
public关键字而不是dim（默认情况下为私有）声明它们。即
以下应该可以正常工作。
公共类Form1
公共类DOG
公共颜色为字符串
公共年龄为整数
公共名称为字符串
结束班级
Public Sub Button1_Click（ByVal sender As System.Object，ByVal e As
System.EventArgs）处理Button1.Click
Dim WOLF作为新DOG
WOLF.AGE = 10
End Sub
结束课
Brian写道：
Because the property variables aren''t visible. Declare them with the
public keyword instead of dim (which is private by default). i.e. The
following should work just fine.
Public Class Form1
Public Class DOG
Public COLOUR As String
Public AGE As Integer
Public NAME As String
End Class
Public Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim WOLF As New DOG
WOLF.AGE = 10
End Sub
End Class

Brian，
虽然它可能会起作用，但它却像罪一样难看。你应该将你的DOG类
分成另一个文件。此外，不是公开使用字段，而是应该将b / b $ b变为私有，而是提供公共属性。

Brian,
While it may work, it''s ugly as sin. You should separate your DOG class
out into a different file. Also, instead of using fields publicly you should
make them private and provide public properties instead.
