Question

I need to group items together where two or more fields match each other. I am not exactly sure how to accomplish this.

Here’s some example data:

   TIME  |        TITLE            |   CHANNEL
---------+-------------------------+---------------
  10:00  |  Liverpool-Manchester   |   Viasat
  10:00  |  Liverpool-Manchester   |  Viasat HD
  10:00  |         Bla-debla       |  OtherChannel
  10:00  |        team1-team2      |  SomeChannel
  10:00  |        team1-team2      | SomeChannel HD

I want to group items where TIME and TITLE match. Like below.

First grouped items:

  10:00  |   Liverpool-Manchester   |  Viasat
  10:00  |   Liverpool-Manchester   | Viasat HD

Second grouped items:

  10:00  |   Bla-debla              |  OtherChannel

Third grouped items:

  10:00  |   team1-team2            | SomeChannel
  10:00  |   team1-team2            | SomeChannel HD

Any idea how to accomplish this?

Answer 1

Try the following please:

from c in collection
group c.Title by new {c.Title,c.Time} into t
where t.Count()>1
select t;

You will need to introduce new anonymous type if you want to group by more than one property and specify the properties in there

Not tested but should work.
