I find this code

FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://www.contoso.com/test.htm");
        request.Method = WebRequestMethods.Ftp.UploadFile;

        // This example assumes the FTP site uses anonymous logon.
        request.Credentials = new NetworkCredential ("anonymous","janeDoe@contoso.com");

but

how i can upload my file to another host with ftp and get url place of save file?

Answer 1

you choose the path where you upload to ftp appending directories to the FTP address:

string CompleteDPath = "ftp://yourFtpHost/folder1/folder2/";

string FileName = "yourfile.txt";

And here you have a working example I found once:

WebRequest reqObj = WebRequest.Create(CompleteDPath + FileName);
The following script work great with me for uploading files and videos to another servier via ftp.

FtpWebRequest ftpClient = (FtpWebRequest)FtpWebRequest.Create(ftpurl + "" + username + "_" + filename);
ftpClient.Credentials = new System.Net.NetworkCredential(ftpusername, ftppassword);
ftpClient.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
ftpClient.UseBinary = true;
ftpClient.KeepAlive = true;
System.IO.FileInfo fi = new System.IO.FileInfo(fileurl);
ftpClient.ContentLength = fi.Length;
byte[] buffer = new byte[4097];
int bytes = 0;
int total_bytes = (int)fi.Length;
System.IO.FileStream fs = fi.OpenRead();
System.IO.Stream rs = ftpClient.GetRequestStream();
while (total_bytes > 0)
{
   bytes = fs.Read(buffer, 0, buffer.Length);
   rs.Write(buffer, 0, bytes);
   total_bytes = total_bytes - bytes;
}
//fs.Flush();
fs.Close();
rs.Close();
FtpWebResponse uploadResponse = (FtpWebResponse)ftpClient.GetResponse();
value = uploadResponse.StatusDescription;
uploadResponse.Close();
