VB.NET 如何动态添加组件,如FileSystemWatcher,并且响应同一事件?

For Each i In My.Computer.FileSystem.Drives

Dim FSW As New FileSystemWatcher

FSW.NotifyFilter = NotifyFilters.FileName

FSW.Path = i.Name.ToString

FSW.Filter = "*.txt"

AddHandler FSW.Changed, AddressOf FileSystemWatcher1_Changed '与FileSystemWatcher1_Changed事件绑定,以下同。

AddHandler FSW.Created, AddressOf FileSystemWatcher1_Created

AddHandler FSW.Deleted, AddressOf FileSystemWatcher1_Deleted

AddHandler FSW.Disposed, AddressOf FileSystemWatcher1_Disposed

AddHandler FSW.Error, AddressOf FileSystemWatcher1_Error

AddHandler FSW.Renamed, AddressOf FileSystemWatcher1_Renamed

FSW.EnableRaisingEvents = True

Next

上面代码放到一个调用过程中

Private Sub FileSystemWatcher1_Created(sender As Object, e As FileSystemEventArgs) Handles FileSystemWatcher1.Created

‘我用fsw的path属性区别多个分区,你用自己的代码就行,如果你没有创建FileSystemWatcher1,就把Handles FileSystemWatcher1.Created删除。

If sender.path = "C:\" Then

'代码

ElseIf sender.path = "D:\" Then

'代码

ElseIf sender.path = "F:\" Then

ElseIf sender.path = "H:\" Then

'……

End If

End Sub
