SOS！告诉我如何在WebForm实现用按钮浏览本地目录；

[zglet]

他要实现的功能就像发送电子邮件时，添加附件，使用浏览按钮的功能！

<form enctype="multipart/form-data" runat="server">

Select File to Upload:
<input id="File1"
type="file"
runat="server">

<p>
Save as filename (no path):
<input id="Text1"
type="text"
runat="server">

<p>
<span id=Span1
style="font: 8pt verdana;"
runat="server" />

<p>
<input type=button
id="Button1"
value="Upload"
OnServerClick="Button1_Click"
runat="server">

</form>

<script language="VB" runat="server">
Sub Button1_Click(Source As Object, e As EventArgs)

If Text1.Value = "" Then
Span1.InnerHtml = "Error: you must enter a file name"
Return
End If

If Not (File1.PostedFile Is Nothing) Then
Try
File1.PostedFile.SaveAs(("c:\temp\" + Text1.Value))
Span1.InnerHtml = "File uploaded successfully to <b>c:\\temp\\" & _
Text1.Value & "</b> on the Web server"
Catch exc As Exception
Span1.InnerHtml = "Error saving file <b>c:\\temp\\" & _
Text1.Value & "</b><br>" & exc.ToString()
End Try
End If
End Sub 'Button1_Click
</script>
