Upload a file (jpg) from hard disk to webserver

Paulo,
First of all you need rights to upload files to the url using.
Check with your team necessary ports are opened or not.

Hi Paulo
I can you give two different methods to upload files from a desktop application to a webserver:
By using FTP (this is the easier one):
public void UploadMyFile()  {
// Get the object used to communicate with the server.
string myFtp = ftp://mydomain.com/fileOnFtp.html;
string myFtpUserName = "aassddff";
string myFtpPassword = "xxxxxxx";
string myLocalFile = @"c:\\text.txt";
System.Net.FtpWebRequest request = (System.Net.FtpWebRequest)System.Net.WebRequest.Create(myFtp);
request.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
request.Credentials = new System.Net.NetworkCredential(myFtpUserName, myFtpPassword);

//get your local file into stream
System.IO.StreamReader sr = new System.IO.StreamReader(myLocalFile);
byte[] fileInBytes = System.Text.Encoding.UTF8.GetBytes(sr.ReadToEnd());
sr.Close();

request.ContentLength = fileInBytes.Length;
System.IO.Stream reqStream = request.GetRequestStream();
reqStream.Write(fileInBytes, 0, fileInBytes.Length);
reqStream.Close();

System.Net.FtpWebResponse response = (System.Net.FtpWebResponse)request.GetResponse();
Console.WriteLine("File has been successfully uploaded. " + response.StatusDescription);
response.Close();
}
. By using a Web Service:
This is a harder one, and requires more coding. So, I'll just tell you the steps

1. Create a web service on the web hosting application. In the web service create a web method something like:
   public string UploadFile (string fileName, string fileContent)
   
   fileName: name of the file to be uploaded.
   fileContent: file's content in Base64 string
   
   The method should convert Base64 to byte array and saves it on the web server.
2. On the desktop application:
   Read the file from the local drive. Conver the file's content to Base64 string. Then call the UploadFile web method.

As I mentioned the second one requires more coding, but I think it is a better solution; you can check your file's content, add some extra security.
good luck
