Uplode filer til MS´s mailmessage

Jeg har lavet en mailmessage efter MS eksempel. Se:
<!-- http://msdn.microsoft.com/en-us/library/system.web.mail.mailmessage.aspx  -->

Det virker pånær attached file. Men MS skriver heller ikke hvordan man skal lave det.

Til at uplode filer har jeg brugt:

<asp:FileUpload id="FileUpload1" runat="server" Width="305px" />
           
<asp:Button id="UploadButton" Text="Upload file" OnClick="UploadButton_Click" runat="server" Width="70px"> </asp:Button>           
           
Sub UploadButton_Click(ByVal sender As Object, ByVal e As System.EventArgs)
           
    ' Specify the path on the server to
    ' save the uploaded file to.
    Dim savePath As String = "c:\temp\uploads\"
       
    ' Before attempting to perform operations
    ' on the file, verify that the FileUpload
    ' control contains a file.
    If (FileUpload1.HasFile) Then
      ' Get the name of the file to upload.
      Dim fileName As String = FileUpload1.FileName
                     
      ' Append the name of the file to upload to the path.
      savePath += fileName
               
      ' Call the SaveAs method to save the
      ' uploaded file to the specified path.
      ' This example does not perform all
      ' the necessary error checking.             
      ' If a file with the same name
      ' already exists in the specified path, 
      ' the uploaded file overwrites it.
      FileUpload1.SaveAs(savePath)
               
      ' Notify the user of the name the file
      ' was saved under.
      txtAttach.Text = fileName
               
    Else
      ' Notify the user that a file was not uploaded.
      txtAttach.Text = ""
    End If


Jeg får (selvfølgelig) fejlen c:\temp\uploads\ ikke findes på serveren.
Hvordan får man filerne loded ind????
