I'm not sure where the best article would be found, but I'm sure you could
find plenty with a search. But here is a basic example that should get you
started:
If fileupload1.HasFile AndAlso fileupload1.FileContent.Length > 0 Then
If Not System.IO.File.Exists(Server.MapPath(String.Concat("/",
fileupload1.FileName))) Then
Me.fileupload1.PostedFile.SaveAs(Server.MapPath(String.Concat("/",
fileupload1.FileName)))
End If
End If
The first If statement checks to make sure a file has been selected and that
the file actually has content. The second If statement checks to make sure
that there is not already a file in the directory with that name. If both of
these If statements pass, then the SaveAs method of the PostedFile property
of the FileUpload control is called. Take note that you do not have to use
the filename of the original file, although whether or not you do depends on
the intended usage of you application. Also, take note of the Server.MapPath
function that I used. This is important, because you must specify the path
on the server. Hopefully this will get you started; if you have any
questions that you cannot find answers to, feel free to ask.
