LINQ
Hi Is there a better simplified way to write this query. My logic is if collection contains customer ids and countrycodes, do the query ordey by customer id ascending. If there are no contain id in CustIDs then do the order by customer name. Is there a better way to write this query? I'm not really familiar with complex lambdas.
var custIdResult = (from Customer c in CustomerCollection
where (c.CustomerID.ToLower().Contains(param.ToLower()) &&
(countryCodeFilters.Any(item => item.Equals(c.CountryCode))) )
select c).ToList();
if (custIdResult.Count > 0)
{
return from Customer c in custIdResult
( c.CustomerName.ToLower().Contains(param.ToLower()) &&
countryCodeFilters.Any(item => item.Equals(c.CountryCode)) )
orderby c.CustomerID ascending
select c;
}
else
{
return from Customer c in CustomerCollection
where ( c.CustomerName.ToLower().Contains(param.ToLower()) &&
countryCodeFilters.Any(item => item.Equals(c.CountryCode)) )
orderby c.CustomerName descending
select c;
}
