通常，覆盖将出现在实例化的类中。在你的
示例中，用于创建myobject的类。

''ToString''必须在属性类型或其中一个
基类中实现。示例：
\\\
公共类人员
私人m_Age为整数
私有m_Name为字符串
公共财产年龄（）为整数
获取
返回m_Age
结束获取
设置（ByVal值为整数）
m_Age =价值
结束集
结束物业
公共属性名称（）为字符串
获取
返回m_Name
结束获取
套装（ByVal Value As String）
m_Name =价值
套装
结束物业
Public Overrides Function ToString（）As String
返回名称& " （& CStr（Age）&"）"
结束功能
结束课程
..
..
..
Dim p As New Person（）
p.Age = 44
p.Name =" Pink Panther"
MsgBox（p.ToString（））''" Pink Panther（44）"。

I have a property where I want to associate tostring with
it. So that this would be valid:
-----
Dim x as string
x = myobject.myproperty.tostring
-----
I know I have to overide tostring() but where do I do
that to get my desired result?
Thanks!

Normally, the override would appear in the instantiated class. In your
example, the class that was used to create myobject.

''ToString'' must be implemented in the type of the property or one of its
base classes. Example:
\\\
Public Class Person
Private m_Age As Integer
Private m_Name As String
Public Property Age() As Integer
Get
Return m_Age
End Get
Set(ByVal Value As Integer)
m_Age = 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 Overrides Function ToString() As String
Return Name & " (" & CStr(Age) & ")"
End Function
End Class
..
..
..
Dim p As New Person()
p.Age = 44
p.Name = "Pink Panther"
MsgBox(p.ToString()) '' "Pink Panther (44)".
