.net - Upload file to FTP site using VB.NET

Question

I have this working code from this link, to upload a file to an ftp site:

' set up request...
Dim clsRequest As System.Net.FtpWebRequest = _
    DirectCast(System.Net.WebRequest.Create("ftp://ftp.myserver.com/test.txt"), System.Net.FtpWebRequest)
clsRequest.Credentials = New System.Net.NetworkCredential("myusername", "mypassword")
clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile

' read in file...
Dim bFile() As Byte = System.IO.File.ReadAllBytes("C:Tempest.txt")

' upload file...
Dim clsStream As System.IO.Stream = _
    clsRequest.GetRequestStream()
clsStream.Write(bFile, 0, bFile.Length)
clsStream.Close()
clsStream.Dispose()

I wonder, if the file already exists in the ftp directory, the file will be overwritten?

Answer 1

Looking at the MSDN documentation this maps to the FTP STOR command. Looking at the definition for the FTP STOR command it will overwrite existing files, if the user has permissions.

So in this case, yes the file would be overwritten.
