Question

所以我曾经能够做到这一点，但忘了如何，因为我必须重新开始，它的部分

Dim bFile() As Byte = System.IO.File.ReadAllBytes(bmp)

这就是问题，我只是需要上传test.image甚至bmp（我保存的位图）或以某种方式从文件流上传图像，因为我不想保存到计算机磁盘......

        Dim clsRequest As System.Net.FtpWebRequest = _
DirectCast(System.Net.WebRequest.Create("ftp://ftp.myURL.info"), 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(bmp)
        ' upload file...         
        Dim clsStream As System.IO.Stream = _
        clsRequest.GetRequestStream()
        clsStream.Write(bFile, 0, bFile.Length)
        clsStream.Close()
        clsStream.Dispose()

试试这个：

上传图片：

Using ms As New System.IO.MemoryStream
    PictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Png)
    Using wc As New System.Net.WebClient
        wc.UploadData("ftp://foo.com/bar/mumble.png", ms.ToArray())
