从Web服务调用方法时，SessionId发生更改

Question

I have two projects. One of them has a WebService(asmx) and the second one uses the WebService as a reference.

This is the WebMethod:

[WebMethod(EnableSession = true)]
public int GetDocCount(CompressedData data)
{
    if (Session[Settings.cStrSessionUserLogin] == null)
    {
        return 0;   
    }
    string xmlString = EncoderUtil.Decompress(data);
    SortFilterSet sfs = (SortFilterSet)XmlUtil.Deserialize(typeof(SortFilterSet), xmlString);
    Session[Settings.cStrSessionSortFilterSet] = sfs;
    Session[Settings.cStrSessionOrderCodeList] = null;      

    return Database.GetOrderCount((List<RequestorInfo>)Session[Settings.cStrSessionRequestorList], sfs.FilterSet, sfs.SearchPattern);
}

When i create the client i have one sessionid, but whenever i call the WebMethod i see the SessionId changes inside the WebMethod(i can see that with Debug)

MyWebServiceSoapClient client = new MyWebServiceSoapClient();
int countDocs = client.GetDocCount(data);

Why am I seeing a new SessionId in the WebMethod, and how can I avoid this and get the original SessionId?

EDIT : Inside the WebMethod Session.Count is always 0

Answer 1

I deleted the WebService reference and then i inserted the MyWebServiceSoapClient.asmx and MyWebServiceSoapClient.cs in my project. Now i don't get the new SesseionId's anymore.
