[VB / ASP.NET] FileUpload控件，档案上传

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
