First of all you are adding items in gatewayConnectionPropertyDataList (I am not sure what it is) but if you are expecting the data in mydataList you need to add in this variable only. Also, you can use collection initializers for this like this:-

List<gatewayConnectionPropertyData> mydataList = 
                                new List<gatewayConnectionPropertyData>
{
  new gatewayConnectionPropertyData { url = "/testproposal.xml", type = 13, 
                                             service_desc = "proposal" },
  new gatewayConnectionPropertyData { url = "/testUtulity.xml", type = 12, 
                                             service_desc = "utility" },
  new gatewayConnectionPropertyData { url = "/testinteligence.xml", type = 53,
                                             service_desc = "intelligence" },
};
