如何确定我在CATCH中获得的WHICH异常？

如果TypeOf ex是SpecificExceptionIWant那么 .... 具体例子： D as a Integer = 1，b As Integer = 0，c As Integer 尝试 c = a \ b Catch ex As Exception 如果TypeOf ex是DivideByZeroException那么 MsgBox（不要惊讶） 否则 MsgBox（Wething weIRD） 结束如果 结束尝试 这就像寻找特定的Err一样。 VB6中的数字'，这是我怀疑你正在寻找的。 - Larry Lard 回复团体请 Its type. If TypeOf ex Is SpecificExceptionIWant Then.... Concrete example: Dim a As Integer = 1, b As Integer = 0, c As Integer Tryc = a \ bCatch ex As ExceptionIf TypeOf ex Is DivideByZeroException ThenMsgBox("No surprise")ElseMsgBox("Something WEIRD")End IfEnd Try This is exactly like looking for specific Err.Number''s in VB6, which iswhat I suspect you are looking for.--Larry LardReplies to group please \\\ 如果TypeOf ex是FooException那么 ... ElseIf TypeOf ex是GooException然后 ... .... 结束如果 /// - 或 - \\\ Select Case True Case TypeOf ex FooException .. 。 案例类型以前是GooException ... ... 结束选择 /// 请注意，FxCop会抱怨捕获块，它们会捕获通用的 异常类型。但是，这个规则是有争议的，可能会改变/删除。关于这个问题的德国文章： 神话：Catch（例外）是什么b？se < URL：http：//www.die.de/博客/ PermaLink.aspx？guid = c0d9a5d0-b12d-4995-8447-94040a932dc9> - MS Herfried K.
