Catch multiple exceptions at the same time
提问by SysDragon
There is sometimes that one want to do the same on two different types of Exception. I searched, but I didn't find anything for VB.NET.
有时人们想对两种不同类型的异常做同样的事情。我进行了搜索，但没有找到有关 VB.NET 的任何内容。
Simple example:
简单的例子：
Try
'...
Catch ex As Net.WebException
'Do something
Catch ex As Net.CookieException
'Do the same
Catch ex As Exception
'...
End Try
I wonder if there is a way to catch both exceptions at once without needed to repeat code.
我想知道是否有一种方法可以同时捕获两个异常而无需重复代码。

As seen on Catch multiple exceptions at once?it can be done this way:
正如在一次捕获多个异常中看到的那样？可以这样做：
Catch ex As Exception When TypeOf ex Is FormatException OrElse TypeOf ex Is OverflowException
