How do I select using more than one parameter in a LINQ join?

Question

I need to select on two variables for this LINQ request, however "&&" and "and" do not work as shown below. What is the correct way to accomplish this?
var requestDetailList =
   from requests in ds.Tables[0].AsEnumerable()
   join settings in ds.Tables[1].AsEnumerable()
   on requests.Field<long>("RequestFileDetailID") equals settings.Field<long>("AlertServiceEnrollmentRequestID")    
   && settings.Field<long>("AlertServiceEnrollmentTypeID") equals AlertServiceRequestType.ClubUtilization)
   into ClubSettings
   from cs in ClubSettings.DefaultIfEmpty()
   select new AMEnrollRequestInfo_EX
   {
       FileDetailID = Convert.ToInt32(requests.Field<long>("RequestFileDetailID")),		       ClubUtilizationLimit = (cs == null) ? string.Empty : cs.Field<string>("AlertServiceEnrollmentSettingValue")
   };
