Upload file via POST call with C#, RestSharp, Redmine API

I'm developing a C# app that uses Redmine REST API, it uses RestSharp Client. All other REST calls I make work fine but I cannot find a way to upload attachments. I've widely searched the web and tried many solutions but nothing worked. Redmine documentiation on attachments: http://www.redmine.org/projects/redmine/wiki/Rest_api#Attaching-files The code actually looks like: 

RestClient client = new RestClient("http://myclient/redmine/");
client.Authenticator = new HttpBasicAuthenticator("myuser", "mypsw");
var request2 = new RestRequest("uploads.json", Method.POST);
request2.AddHeader("Content-Type", "application/octet-stream");
request2.RequestFormat = RestSharp.DataFormat.Json;
byte[] dataToSend = File.ReadAllBytes(AddIssue.attach.Text);
request2.AddBody(dataToSend);
IRestResponse response2 = client.Execute(request2);
resultbox.Text = response2.Content;

If I execute it above nothing happens and the response is empty. If I remove line 7 (the AddBody), it actually works but of course nothing is uploaded, JSON response: { "upload": { "token": "11." } }

So actually, the real question is what to punt in AddBody() to send the file as application/octet-stream. Since RestSharp also has a request.AddFile() method, I tried it too in different ways but nothing...

Any help much appreciated!

As I mentioned in my comment, it sounds like Redmine might have requirements similar to Dropbox. Here is the solution that worked for me (based on the question Upload to dropbox using Restsharp PCL):

public static void UploadFileToDropbox(string filePath)
{
    RestClient client = new RestClient("https://api-content.dropbox.com/1/");
    IRestRequest request = new RestRequest("files_put/auto/{path}", Method.PUT);

    FileInfo fileInfo = new FileInfo(filePath);
    long fileLength = fileInfo.Length;

    request.AddHeader("Authorization", "Bearer INSERT_DEVELOPER_TOKEN_HERE");
    request.AddHeader("Content-Length", fileLength.ToString());

    request.AddUrlSegment("path", string.Format("Public/{0}", fileInfo.Name));

    byte[] data = File.ReadAllBytes(filePath);
    var body = new Parameter
    {
        Name = "file",
        Value = data,
        Type = ParameterType.RequestBody,
    };
    request.Parameters.Add(body);

    IRestResponse response = client.Execute(request);
}

Also published as a Gist.

I know this isn't your exact situation, but hopefully it gives you some ideas.
