不可能？谁叫方法？ [英] Impossible? Who called the Method?
问题描述
如何在给定方法中知道它被调用的方法？
例如：我有两个属性'（Prenom和Nom），都调用方法
PropertyChangedHandler（）。如何知道PropertyChangedHandle是否被Prenom或Nom称为
？
公共事件PrenomChanged As EventHandler
公共财产Prenom（）As String
获取
返回m_strPrenom
结束获取
设置（ByVal值为字符串）
m_strPrenom =价值
RaiseEvent PrenomChanged（我，New EventArgs（））
PropertyChangedHandler（）
结束集
结束物业
公共事件NomChanged As EventHandler
Public Property Nom（）As String
Get
返回m_strNom
结束获取
设置（ByVal值为字符串）
m_strNom = Value
RaiseEvent NomChanged（我，新EventArgs（））
PropertyChangedHandler（）
结束集
结束财产
Private Sub PropertyChangedHandler（）
''我想在这个方法中知道哪个属性叫它：Prenom或
Nom ...
End Sub
我可以把这个属性的名字放在这样的参数中：
PropertyChangedHandler（Nom）等等。但在我看来它是'不是真的很好
解决方案:-)那么有没有办法用一个解决方案来做到这一点没有每次
必须使用一个独特的变量？发件人对象之类的东西？
提前多多谢谢，
Pieter
Hi,
How can I know inside a given method, by which method it was called?
For instance: I have two property''s (Prenom and Nom), both call the Method
PropertyChangedHandler(). How Can I know if PropertyChangedHandle was called
by the Prenom or by Nom?
Public Event PrenomChanged As EventHandler
Public Property Prenom() As String
Get
Return m_strPrenom
End Get
Set(ByVal Value As String)
m_strPrenom = Value
RaiseEvent PrenomChanged(Me, New EventArgs())
PropertyChangedHandler()
End Set
End Property
Public Event NomChanged As EventHandler
Public Property Nom() As String
Get
Return m_strNom
End Get
Set(ByVal Value As String)
m_strNom = Value
RaiseEvent NomChanged(Me, New EventArgs())
PropertyChangedHandler()
End Set
End Property
Private Sub PropertyChangedHandler()
''I Want to know in this Method which property called it: Prenom or
Nom...
End Sub
I could put the name of the property in a paramter like this:
PropertyChangedHandler("Nom") etc. But in my opinion it''s not really a nice
solution :-) So is there any way to do it with a solution without everytime
having to use a unique variable? something like the sender-object?
Thanks a lot in advance,
Pieter
推荐答案
TraceEvent.Callstack可能有用，如果你使用vb2005
如果你想传递方法名作为参数使用
MethodBase.GetCurrentMethod.Name
如果更改方法名称，新名称就会通过

if you want to pass the method name as a parameter use
MethodBase.GetCurrentMethod.Name

抱歉应该是TraceEventCache.CallStack
或者你可以使用Environment.StackTrace
