Post attachment to Jira using REST API in c#

Question

I Have a problem. When I want to POST some attachment to JIRA using REST API i have a Web Exception with 404 code (not found). My method takes CookieContainer to authenticate User. This is my code:

 HttpWebResponse response;
        string path = "C:\\Users\\xxxx\\Documents\\nowy.txt";
        var boundary = string.Format("----------{0:N}", Guid.NewGuid());
        request.CookieContainer = new CookieContainer();
        foreach (Cookie c in responseCookies)
            request.CookieContainer.Add(c);
        request.ContentType = String.Format("multipart/form-data; boundary={0}", boundary);
        request.Method = "POST";
        request.Headers.Add("X-Atlassian-Token: nocheck file=@my_file.txt");
        request.Headers.Add("charset", "UTF-8");
        request.KeepAlive = false; 

        var fileContent = File.ReadAllBytes(path);

        request.ProtocolVersion = HttpVersion.Version10;
        using(var streamWriter = new StreamWriter(request.GetRequestStream()))
        {
            streamWriter.Write(fileContent);
        }


        response = request.GetResponse() as HttpWebResponse;
        Stream s = response.GetResponseStream();

I used for many support, but any resolved my problem. So do you have some idea?

EDIT 1

now Jira returns 200 code but attachment was not added.. can you tell me what's wrong in my code?

public void AddAtachment(CookieCollection responseCookies)
    {
        request.CookieContainer = new CookieContainer();
        foreach (Cookie c in responseCookies)
            request.CookieContainer.Add(c);
        Console.Write(request.RequestUri);
        HttpWebResponse response;
        string fileUrl = @"C:\Users\xxxx\Documents\nowy.txt";
        var boundary = string.Format("----------{0:N}", Guid.NewGuid());


        request.ContentType = String.Format("multipart/form-data; boundary={0}", boundary);
        request.Method = "POST";
        request.Headers.Add("X-Atlassian-Token", "nocheck");

        MemoryStream postDataStream = new MemoryStream();
        StreamWriter postDataWriter = new StreamWriter(postDataStream);

        postDataWriter.Write("\r\n--" + boundary + "\r\n");
        postDataWriter.Write("Content-Disposition: form-data;"
                    + "@file=\"{0}\";"
                    + "filename=\"{1}\""
                    + "\r\nContent-Type: {2}\r\n\r\n",
                    "myFile",
                    Path.GetFileName(fileUrl),
                    Path.GetExtension(fileUrl));
        postDataWriter.Flush();

        FileStream fileStream = new FileStream(fileUrl, FileMode.Open, FileAccess.Read);
        byte[] buffer = new byte[1024];
        int bytesRead = 0;
        while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
        {
            postDataStream.Write(buffer, 0, bytesRead);
        }

        fileStream.Close();

        postDataWriter.Write("\r\n--" + boundary + "--\r\n");
        postDataWriter.Flush();

        request.ContentLength = postDataStream.Length;

        using (Stream s = request.GetRequestStream())
        {
            postDataStream.WriteTo(s);
        }

        postDataStream.Close();

        response = request.GetResponse() as HttpWebResponse;
        StreamReader responseReader = new StreamReader(response.GetResponseStream());
        string reply = responseReader.ReadToEnd();
        Console.Write(reply);
    }

Possible duplicate of How to POST attachment to JIRA using REST API? .

From what I can see, your problem is in the Content-Disposition header. RFC-1867 expects the form-data name to be "file" and nothing else. For more details, look at the post on Atlassian Forums: https://answers.atlassian.com/questions/104822/jira-rest-api-attachment-incoherent-result .
