I'm trying to upload a file to the media archive but when i dont hardcode the parentnode in my SetValue i get this error "No overload for method 'SetValue' takes '3' arguments"

This gives me the error

System.Web.HttpFileCollectionBase files = Request.Files;
string[] fieldNames = files.AllKeys;

for (int i = 0; i < fieldNames.Length; ++i)
{
string field = fieldNames[i];


if(field == "kontraktfile" && Request.Files[i].ContentLength > 0){
var kontrakt = _mediaService.CreateMedia(Request.Files[i].FileName, Umbraco.Media(1263).Id, "File");
s = Request.Files[i].InputStream;
kontrakt.SetValue("umbracoFile", Request.Files[i].FileName, s);
s.Close();
_mediaService.Save(kontrakt);
}

This does not

System.Web.HttpFileCollectionBase files = Request.Files;
string[] fieldNames = files.AllKeys;

for (int i = 0; i < fieldNames.Length; ++i)
{
string field = fieldNames[i];


if(field == "kontraktfile" && Request.Files[i].ContentLength > 0){
var kontrakt = _mediaService.CreateMedia(Request.Files[i].FileName, 1263, "File");
s = Request.Files[i].InputStream;
kontrakt.SetValue("umbracoFile", Request.Files[i].FileName, s);
s.Close();
_mediaService.Save(kontrakt);
}

So i dont really understand why Umbraco.Media(1263).Id and 1263 isnt identical. This is on Umbraco 7.10.4.
