string SAP_ODATA_URL = @"http://ApplicationURL";
string SAP_ODATA_QUERY = "MethodName?$filter=Parameter eq '" + extensionAttribute13 + "'";
string requestUrl = SAP_ODATA_URL + SAP_ODATA_QUERY;
WebRequest request = WebRequest.Create(requestUrl);
request.Method = WebRequestMethods.Http.Get;
request.ContentType = "application/json; charset=utf-8";
request.Credentials = new NetworkCredential("XXX", "XXX");
WebResponse response = request.GetResponse();
if (((HttpWebResponse)response).StatusCode == HttpStatusCode.OK)
{
    Stream receiveStream = response.GetResponseStream();
    StreamReader reader = new StreamReader(receiveStream);
    string responseFromServer = reader.ReadToEnd();
    XmlTextReader xmlReader = new XmlTextReader(new StringReader(responseFromServer));
    xmlReader.Read();
    DataSet ds = new DataSet();
    ds.ReadXml(xmlReader, XmlReadMode.Auto);
}
