怎么做“WithEvents”在C＃？ [英] How to do "WithEvents" in C#?
问题描述
这个VB.NET代码的C＃等价物是什么：
Private WithEvents IE_Inst As New SHDocVw.InternetExplorer
我得到：
private SHDocVw.InternetExplorer IE_Inst = new SHDocVw.InternetExplorer（）;
但我不知道如何翻译WithEvents部分。有什么建议吗？
谢谢，
Brett
What is the C# equivalent for this VB.NET code:
Private WithEvents IE_Inst As New SHDocVw.InternetExplorer
I get as far as:
private SHDocVw.InternetExplorer IE_Inst = new SHDocVw.InternetExplorer();
but am not sure how to translate the WithEvents part. Any suggestions?
Thanks,
Brett

>这个VB.NET代码的C＃等价物是什么：Private WithEvents
> What is the C# equivalent for this VB.NET code: Private WithEvents
IE_Inst As New SHDocVw.InternetExplorer
IE_Inst As New SHDocVw.InternetExplorer
C＃不直接支持WithEvents 。

您的问题：
你必须定义每个事件，你要在哪里使用事件处理程序，
明确：
SHDocVw.Event1 + = new EventHandler（ HandleEvent_Function1）;
SHDocVw.Event2 + = new EventHandler（HandleEvent_Function2）;
....

C# does not support WithEvents directly.

To your question:
You have to define each event, where you want to use an event handler,
explicitly:
SHDocVw.Event1 += new EventHandler(HandleEvent_Function1);
SHDocVw.Event2 += new EventHandler(HandleEvent_Function2);

''事件''在C＃中不是必需的。 （它*不应该在VB中被要求，但是
这是一个不同的故事）。

''WithEvents'' is not required in C#. (It *shouldn''t* be required in VB, but
that''s a different story).

别担心。这是VB中关键词腹泻的另一个例子。它好像适用于重载覆盖的白痴。和VB编译器
坚持看到Readonly关键字，即使它可以看到
没有设置访问器。
如果一个类暴露公共事件，那么你可以使用
+ +运算符添加一个处理程序，例如...
theForm.Paint + = new PaintEventHandler （这个painthandler）; //这是相当于AddHandler的
您可以删除类似的事件 - =相当于
removehandler。

Don''t worry about it. It''s another example of keyword diarrhea in VB. It
fits right in with the idiocy of "overloads overrides" and the VB compilers
insistence on seeing the Readonly keyword even when it can see that there is
no set accessor.
If a class exposes public events then you can add a handler to them using
the += operator such as...
theForm.Paint+=new PaintEventHandler(this painthandler); // This is the
equivalent of AddHandler
you can remove events similarly with -= being the equivalent of
removehandler.
