I'm building a program that connects to my site for data. It only needs to write text file. My problem is that I don't know where I have to set up user information, username and password so that my app would be able to change the text file. Here is my code:

C#

Uri uri = new Uri("website");
            WebRequest req = WebRequest.Create(uri);
            WebResponse resp = req.GetResponse();
            Stream stream = resp.GetResponseStream();
            StreamWriter sw = new StreamWriter(stream);

            sw.WriteLine("Something...");

            sw.Close();
            stream.Close(); 
            resp.Close();

I know I can download file,edit it and than upload it, but is there any better way?

could you not do this as part of a webservice call? Your service would reside in the website and external calls communicated with that. Therefore your service would be responsible to the file creation?

It could be a Web service or just a site -- but it needs some sever-side programming and sending the actual request from the client side. I'm not sure OP has a clue on that. Please see my answer.

I agree with db7uk. Use a webservice.

It could be a Web service or just a site -- and OP's thing is the site. No matter what -- it needs some sever-side programming and sending the actual request from the client side.

First of all, you need to send a request; but you are not doing anything like that. In this case, you need to use the class System.Net.HttpWebRequest, create an instance through the factory method as you actually do:
http://msdn.microsoft.com/en-us/library/system.net.webrequest.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx[^].

You will find some code samples in the MSDN articles referenced above.

But most important thing is: the server side should be designed to get a request and interpret it as a request for creation of a file (which is a standard HTTP file upload) or modify the file on some custom request. It works this way, no matter if you have a Web Service or a Web site on the server end. In other words, you need some server-side programming. As this is your site, you can do it, but you need some server-side scripting technology configured for your HTTP server: ASP.NET, PHP, WSGI with Python — you name it.

yep agree. I guess I was being a bit vague.

C#

private bool UploadDocumentWebClient(string FileNamePath, string DestinationUrl)
{
    bool returnValue = false;
    
    try
    {
        
        DestinationUrl = DestinationUrl.Replace(" ", "%20");
        WebClient m_webClient = new WebClient();
        m_webClient.Credentials = new NetworkCredential("UserName", "Password", "Domain");
        m_webClient.UploadFile(DestinationUrl, "PUT", FileNamePath);
        returnValue = true;
    }
    catch
