我在一些代码中放置了一个try / catch块,偶尔抛出一个预期的异常,但不是捕获它并显示消息框,它会停止调试器并提醒我异常未处理. 如何处理此异常,以便在发生异常时我的代码不会停止
          如何处理此异常,以便在发生异常时我的代码不会停止?
Friend myDevInfo As New devInfo
        ''' <summary>
        ''' Closes the device handle obtained with CreateFile and frees resources.
        ''' </summary>
        ''' 
        Friend Sub CloseDeviceHandle()
            Try
                WinUsb_Free(myDevInfo.winUsbHandle)
                If Not (myDevInfo.deviceHandle Is Nothing) Then
                    If Not (myDevInfo.deviceHandle.IsInvalid) Then
                        myDevInfo.deviceHandle.Close()
                    End If
                End If
            Catch ex As System.AccessViolationException
                MsgBox("System.AccessViolationException")
            Catch ex As Exception
                Throw
            End Try
        End Sub
 当没有附加调试器时,try … catch块应该按预期工作. 您可以在Debug – >下定义调试器中断的异常.例外,我认为默认是在AccessViolationException上中断.
