How to read Product Properties from a data set

To retrieve product properties from the server, you should typically call QlmLicense.GetProductProperties.

If you are already calling QlmLicense.GetDataSet, you already have the product properties in the dataset. You can therefore read them as shown in the example below.

string dataSet = string.Empty;
string response;

lv.QlmLicenseObject.GetDataSet(string.Empty, "SubscriptionExpiryDate > '2019-08-20'", ref dataSet, out response);

DataSet ds = new DataSet("NewDataSet");
XmlReader reader = new XmlTextReader(dataSet, XmlNodeType.Document, null);

if (!String.IsNullOrEmpty(dataSet))
{
    ds.ReadXml(reader);

    if (ds.Tables[0].Rows.Count > 0)
    {
        DataRowCollection drc = ds.Tables[0].Rows;

        if (drc != null)
        {
            foreach (DataRow dr in drc)
            {
               string pp = dr["Properties"].ToString();
               if (!String.IsNullOrEmpty(pp))
               {
                   IQlmProductProperties pps = new QlmProductProperties(pp);
                   IQlmProductProperty prop = pps.GetProperty("category1", "property1");
                   if (prop != null)
                   {
                       string val = prop.PropValue.ToString();
                       Console.WriteLine(val);
                   }
                }
             }
         }
     }
 }
