求助：（1）以下代码在内部函数里这么写对吗？ （2）在HttpRequest事件代码怎么写？
Dim e As RequestEventArgs = args(0)
Dim fl As String = "d:\web\" & e.path
If filesys.FileExists(fl)
Dim idx As Integer = fl.LastIndexOf(".")
Dim ext As String = fl.SubString(idx)
Select Case ext
Case ".jpg",".gif",".png",".bmp",".wmf",".js",".css" ,".html",".htm",".zip",".rar"
e.WriteFile(fl)
Return "" '这里必须返回
End Select
Dim sb As New StringBuilder
sb.Appendline("产品展示<br/><br/>")
Select Case e.path
Case "a.htm"
sb.AppendLine("<img src='/images/004.jpg'>")
Case "b\a.htm"
sb.AppendLine("<img src='/images/013.jpg'><br/><br/>")
sb.AppendLine("<img src='/images/010.jpg'><br/><br/>")
sb.AppendLine("<img src='/images/011.jpg'><br/><br/>")
sb.AppendLine("<img src='/images/012.jpg'><br/><br/>")
Case "a\a.htm"
sb.AppendLine("<img src='/images/008.mp4'>")
End Select
e.WriteString(sb.ToString())
End If
