试试Catch ......需要我的大脑嘎嘎作响。 [英] Try Catch...need my brain rattled.
问题描述
在离开它之后尝试再次回到.net。
我试图通过尝试找出处理多个事件的正确方法
catch。
我很困惑的是处理3个单独的
事件的正确方法： A，B和C.如果所有3个都能成功执行
，我只希望所有3个执行。
这就是try-catch的用途，或者是主要针对个人
事件的尝试/捕获？
是否有最佳实践方法来处理3个单独事件的检查并且
只有在所有3都可以无误执行的情况下才执行所有3？

Trying to get back into .net again after being out of it for a while.
I''m trying to figure out the proper way to handle multiple events via a try
catch.
What I''m confused about is the proper method to handle, say, 3 separate
events: A, B, and C. I only want all 3 to execute if all 3 can successfully
execute.
Is that what a try-catch is for, or is a try/catch mainly for individual
events?
Is there a best-practice way to handle checking for 3 separate events and
only executing all 3 only if they all can execute without error?

推荐答案
即使有多次捕获，你也可以在try catch中有三个动作
如果有任何失败，它会直接进入捕获，你可以弹出
$ b那时$ b程序。

You could have three actions within a try catch even with multiple catches
If any fail it would go directly to the catch and you could pop outta the
procedure at that point.

尝试... Catch无法处理事件，它处理您的
代码引发的异常。
如果你想编写一个公共事件处理程序（当多个事件触发时，一个名为
的程序），你需要将程序注册为事件
处理程序。在VB .NET中，它很简单：只需扩展Handles即可。
现有事件处理程序的子句，带逗号并列出你想要的其他事件
句柄：
Public Sub multiEventHandler （ByVal sender As System.Object，e As EventArgs）
_
处理Button1.Click，Button2.Click，Button3.Click
在C＃中，它涉及的更多一些。您需要转到Page的Init事件
并将程序注册为特定事件的处理程序：
button1.Click + = button_click（）
button2.Click + = button_click（）
button3.Click + = button_click（）

Try...Catch doesn''t handle events, it handles exceptions raised by your
code.
If you want to write a common event handler (one procedure that is called
when multiple events fire), you need to register the procedures as event
handlers. In VB .NET, it''s easy: just extend the "Handles" clause of an
existing event handler with a comma and list the other events you wish to
handle:
Public Sub multiEventHandler(ByVal sender As System.Object, e As EventArgs)
_
Handles Button1.Click, Button2.Click, Button3.Click
In C#, it''s a bit more involved. You''d need to go to the Page''s Init event
and register the procedures as handlers for a particular events:
button1.Click += button_click()
button2.Click += button_click()
button3.Click += button_click()

对，但那只是按顺序检查它们，对吗？例如：
尝试
A（）
B（）
C（）< br $>
catch
结束尝试
即使C失败，A和B也可以执行？
-Darrel
Right, but that would merely check them sequentially, correct? for example:
Try
A()
B()
C()
catch
end try
A and B could execute even if C fails?
