Getting the ID of a newly uploaded document

Question

How to obtain the ID of a newly uploaded document using web services (c#, .net)? Is the following the best way to obtain Doc ID?

private string sGetID(string sURL, string sListGUID, string sFileName)
{
    string sUser = ConfigurationManager.AppSettings("User");
    string sPwd = ConfigurationManager.AppSettings("Pwd");
    string sDomain = ConfigurationManager.AppSettings("Domain");
    System.Net.NetworkCredential netAccess = new System.Net.NetworkCredential(sUser, sPwd, sDomain);
    SPLists.Lists L = new SPLists.Lists();
    L.Credentials = netAccess;
    L.Url = sURL;
    XmlDocument xmldoc = new XmlDocument();
    XmlNode query = xmldoc.CreateNode(XmlNodeType.Element, "Query", "");
    query.InnerXml = "<OrderBy><FieldRef Name='Modified' " + "Ascending='False'></FieldRef></OrderBy>\"";
    try {
        XmlNode caml = L.GetListItems(sListGUID, null, query, null, "1", null);
        string id = caml.ChildNodes(1).ChildNodes(1).Attributes("ows_ID").Value;
        return id;
    } catch (Exception ex) {
        return ex.Message;
    }
}

Answer 1

I'd add a RowLimit node to the CAML Query, just to be sure to limit the result set to 1, ensures that your web services request brings back only the data it needs (imagine if you had thousands of items in that library!).

Answer 2

_dlc_DocId is the internal field that has allows you to change or retrive the document id. also agree with row limit. but if a newly created/uploaded document as in version 1. then maybe insted of modified you can use created
