[VB / ASP.NET] FileUpload控件，档案上传

http://www.dotblogs.com.tw/mis2000lab/archive/2008/04/24/3455.aspx

以前写ASP要靠第三协力厂商提供的控件才能上传，现在有了「FileUpload」控件，变得很简单。

底下这两个网址，MS提供的范例非常精彩且实用！照抄都能学到东西～棒！

========================================================
这是最基本的用法，上面的URL有其它变形，很实用！

Sub UploadButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)

' Specify the path on the serverto
' save the uploaded file to.
Dim savePath As String = "c:\temp\uploads\"

' Before attempting to performoperations
' on the file, verify that theFileUpload control contains a file.
If (FileUpload1.HasFile)Then
' Get the name ofthe file to upload.
Dim fileNameAs String = FileUpload1.FileName

' Append the nameof the file to upload to the path.
savePath += fileName

' Call the SaveAsmethod to save the
' uploaded fileto the specified path.
' This example doesnot perform all
' the necessaryerror checking.
' If a file withthe same name
' already existsin the specified path,
' the uploaded fileoverwrites it.
FileUpload1.SaveAs(savePath)

' Notify the userof the name the file was saved under.
UploadStatusLabel.Text = "Your file was saved as " & fileName

Else
' Notify the userthat a file was not uploaded.
UploadStatusLabel.Text = "You did not specify a file to upload."
End If

End Sub

这是我写的一个小范例，请笑纳----
