Question

I’m trying to do something like this, and getting compiler errors:

var query = from ev in dataConnection.event_info
                       where ev.isdeleted == 0
                       select ev;
foreach (System.Linq.Expressions.Expression whereCond in whereConditionsList)
{
    query.Where(whereCond);
}

Error:

'System.Linq.IQueryable<JsonApplicationServices.event_info>' does not contain a definition for 'Where' and the best extension method overload 'System.Linq.Enumerable.Where<TSource>(System.Collections.Generic.IEnumerable<TSource>, System.Func<TSource,int,bool>)' has some invalid arguments C:\Users\jzumbrum\perforce_jzumbrum_laptop\jzumbrum_laptop\SlamRun\WCFService\Events.cs 31 21 WCFService

How can I create a collection of where conditions, and then foreach over them?

Answer 1

So I didn’t figure out how to foreach over a where Condition, but I did figure out how to append to my where condition, and my question in a different way here:
stackoverflow answer

The gist of is that you need to add query.AsExpandable.Where()
