Linq. Count records

[shapper]

Hello,

I have a table named Tags which is related to other two tables
ArticlesTags and FilesTags. My Linq select query is:

Dim tags = From t In database.Tags _
Select t.TagID, _
t.Name, _
Active = t.FilesTags.Any Or
t.ArticlesTags. Any

Now I need to create a new query that retrieves 2 values:

1. Total number of existing tags in table Tags
2. Number of all those tags which are related to FilesTags or
ArticlesTags.

I need to retrieve these 2 values.

How can I do this?

Thanks,
Miguel
