Multiple Item support for same property in where clause : LinqExtender
Just a few days ago I have rolled up another patch for LinqExtender which is 1.3.2 , this is reported to me from a work item, especially to support the following query
var query = from book in _context.Books
where book.PublishedDate > someDate
and book.PublishedDate < someDate
select book;
Here we can see that there are similar property is used for different segment in where clause. Now, previously this kind of query used to fail tests as bucket.Items["SomeProperty"].Value and bucket.Items["SomeProperty"].RelationType only returns single item value and relation type respectively. Therefore, I have added a new property that will be used to handle multiple homogenous query conditions and which can be used like the following
IList<BucketItem.QueryCondition> conditions = bucket.Items["SomeProperty"].Values
foreach (BucketItem.QueryCondtion condition in conditions)
{
// do something precious with the value.
obj value = condition.Value;
// contains less, equal, etc.
RelationType rel = condtion.RelationType;
}
In case, your data source don't have that capability for doing this kind of query , and you decide to stick to the single item getter, then the provider will gracefully give "not supported" exception rather than quietly failing the unit test :-). Again, its up to the user how they use it and hope it comes handy.
