Hi,

I want to upload some images in the ftp folder.

I performed it and it worked properly in localhost... but now I uploaded the program on the web and it did not work!!! It has this error:

Could not find a part of the path 'C:\Upload\imagename.jpg'

Would you have any idea about this?

The problem has nothing to do with FTP. The path is not found, that's all.

First of all, there are no cases when a hard-coded path name can be useful. The file paths should always be calculated during runtime based on user input, environment and/or some configuration files. In your case, it's not clear why would you save the file locally at all. If this is the ASP.NET application and the file was already uploaded to your site, you already has its content from HTTP request.

Also, you should understand that your ASP.NET page/application cannot access any arbitrary file in the file system of the HTTP server's host computer. The Web applications are normally executed in a sandboxed environment where the access to the host resources is limited, for important security reasons. In particular, you can only access the file system objects under the root directory configured for your site. See also:

Hi,
I changed it to this code, but still it did not work and has an error:

Could not find file 'C:\Program Files (x86)\Common Files\Microsoft Shared\DevServer\10.0\System.Web.HttpInputStream'.

my code here:

C#

private bool UploadToFTP(string strFTPFilePath, string strLocalFilePath, string strUserName, string strPassword)
        {
            try
            {
                //Create a FTP Request Object and Specfiy a Complete Path
                System.Net.FtpWebRequest reqObj = (FtpWebRequest) WebRequest.Create(strFTPFilePath);

                //Call A FileUpload Method of FTP Request Object
                reqObj.Method = WebRequestMethods.Ftp.UploadFile;

                //If you want to access Resourse Protected,give UserName and PWD
                reqObj.Credentials = new NetworkCredential(strUserName, strPassword);

                // Copy the contents of the file to the byte array.
                FileStream fStream = File.OpenRead(strLocalFilePath);
                byte[] fileContents = new byte[fStream.Length];
                fStream.Read(fileContents, 0, (int) fStream.Length);
                reqObj.ContentLength = fileContents.Length;

                //Upload File to FTPServer
                Stream requestStream = reqObj.GetRequestStream();
                requestStream.Write(fileContents, 0, fileContents.Length);
                requestStream.Close();
                FtpWebResponse response = (FtpWebResponse) reqObj.GetResponse();
                response.Close();
            }

            catch (Exception Ex)
            {
                //throw Ex;
                Label1.Text = Ex.ToString();
            }
            return true;
    }

        
        protected void Button1_Click(object sender, EventArgs e)
        {
            if (imgFileUpload.HasFile)
            {
                string FileName = imgFileUpload.PostedFile.FileName;
                string filePath = "ftp://www.ariavid.com/Upload/";
                filePath += FileName;
                UploadToFTP(filePath, imgFileUpload.PostedFile.InputStream.ToString(), "username", "password");

                Image1.ImageUrl = "ftp://username:password@www.ariavid.com/Upload/" + FileName;
            }
        }
