推荐答案

当你自己使用Catch时，它会捕获抛出的每个异常（并丢弃同时发生的所有信息）。

When you use Catch on it's own, it catches every exception that is thrown (and discards all the information on what happened at the same time).

Dim Top As Double = 5
Dim Bottom As Double = 0
Dim Result As Integer = 0
Try
	Result = Top / Bottom
Catch ex As System.OverflowException
	MessageBox("Attempt to divide by zero:" + ex.Message)
End Try

将Catch限制为可以执行某些操作的例外。

Restricts the Catch to just the exceptions you can do something about.
