Hi any suggestions on building a LINQ statement based on search criteria?
I'll be passing in an instance of a 'SearchCriteria' class with all parameters nullable.
I then want to
if (sc.a != null)
// add to where
if (sc.b != null)
// add to where
The key thing is these are to be ORs not ANDs.
Any tips?
And for bonus points I'd like to use 'contains' on an int? but I can only get equals or not equals.
Try:
.Where(x =>
(x.a != null ? x.a == a : false) &&
(x.b != null ? x.b == b : false));
or
.Where(x =>
(x.a != null && x.a == a) ||
(x.b != null && x.b == b));
Also:
.Where(x => new int[] { 1, 2, 3 }.Contains(x.i));
