ASP.NET file transfer from local machine to another machine

I basically want to transfer a file from the client machine to the file storage server without actual login to the server so that the client cannot access the storage location on the server directly. I can do this only if i manually login to the storage server through windows login. I dont want to do that. This is a Web-Based Application.

Is there any other method to perform the file transfer?

The following is my code:-

protected void Button1_Click(object sender, EventArgs e)  
{  
 
    filePath = FileUpload1.FileName;      
    try  
    {  
        WebClient client = new WebClient();  
 
        NetworkCredential nc = new NetworkCredential(uName, password);  
 
        Uri addy = new Uri("\\\\192.168.1.3\\upload\\");  
        client.Credentials = nc;  
        byte[] arrReturn = client.UploadFile(addy, filePath);  
 
        Console.WriteLine(arrReturn.ToString());  
    }  
    catch (Exception ex)  
    {  
        Console.WriteLine(ex.Message);  
    }  
 
}

The following line doesn't execute...

byte[] arrReturn = client.UploadFile(addy, filePath);

This is the error I get:

An exception occurred during a WebClient request

Ok, i gave the port number too in your code with the IP address and solved the problem. The file gets transferred but the name changes and it changes to an unrecognised file format. How can this be solved?

Hi,
I used your code. Execution stops at the following line :-
Stream ftpstream = ftp.GetRequestStream();
and this is the error that is displayed:-
"Unable to connect to the remote server"

hi friend,
Try below code for uploading file on ftp server with user credentials:

  
    public void ftpfile(string ftpfilepath, string inputfilepath)
    {
        string ftphost = "192.168.1.3";
        //here correct hostname or IP of the ftp server to be given

        string ftpfullpath = "ftp://" + ftphost + ftpfilepath;
        FtpWebRequest ftp = (FtpWebRequest)FtpWebRequest.Create(ftpfullpath);
        ftp.Credentials = new NetworkCredential("userid", "password");
        //userid and password for the ftp server to given

        ftp.KeepAlive = true;
        ftp.UseBinary = true;
        ftp.Method = WebRequestMethods.Ftp.UploadFile;
        FileStream fs = File.OpenRead(inputfilepath);
        byte[] buffer = new byte[fs.Length];
        fs.Read(buffer, 0, buffer.Length);
        fs.Close();
        Stream ftpstream = ftp.GetRequestStream();
        ftpstream.Write(buffer, 0, buffer.Length);
        ftpstream.Close();
    }

Please mark as answer if it helps.
