Getting / receiving data from an online text file

Question

I've been working on this for a few days and can't seem to get it working.

I want to be able to get, and send text (numbers to be specific) to a online file where it can be stored.

At the moment I use:

WebClient wc = new WebClient();
string text = wc.DownloadString("domain.com");            
MessageBox.Show(text);

But it's not great as I can't easily send data, I also want to be able to delete data when its been received a certain amount of times.

I want each item to get uploaded to the same same file, so they can be received individually, and removed one they have been received a certain amount of time.

I have full have access to a web server if needed.

How do I achieve this?

Have tried:

            WebClient WC = new WebClient();
            string myContent = "test";
            string responseString = WC.UploadString("ftp://192.99.1??9.66/www/test.txt", myContent);

Obviously didnt have the question marks.

Answer 1

You should post it as a regular HTTP request, or use something like FTP to write files.

You have the built-in upload methods that do the appropriate HTTP post or FTP requests in the WebClient class already:

byte[] responseArray = wc.UploadFile("ftp://domain/thefile.txt" , @"C:\anyfile.txt");

byte[] responseArray = wc.UploadFile("http://domain/thefile.txt" , @"C:\anyfile.txt");

The last one needs some sort of technology that handles the HTTP POST request, like a webservice. The first one needs an active and accepting FTP server.

Or to send a string :

string myContent = "some data here";

string responseString = wc.UploadString("ftp://domain/thefile.txt" , myContent);
