I have a list of Ids
and I only want to do an AND
on the first one and and OR
on the subsequent ones. In the past, I have kept a counter
variable and when the counter
is 1, I do the And
, but after that I do an OR
, but I was curious if there was an easier way:
foreach(string id in Ids)
{
predicate.And(x=> id.Contains(x.id)); //I want to do an And only on the first id.
}
This is what I have done in the past, but is there a more concise way:
int counter = 1;
foreach (var Id in Ids)
{
string i = Id;
if (counter == 1)
{
predicate = predicate.And(x => i.Contains(x.id));
counter++;
}
else
{
predicate = predicate.Or(x=>i.Contains(x.id));
counter++;
}
}
This works with a local copy of PredicateBuilder (no entityFramework or LinkToSql available at work):
