I am using LINQ in my project and my code is:
var SE = from c in Shop.Sections
join c1 in obj.SectionObjects on c.SectionId equals c1.SectionId
select c;
dataGridView1.DataSource = SE;
but I face this error in line dataGridView1.DataSource = SE;
error message is:
Local sequence cannot be used in LINQ to SQL implementation of query operators except the Contains() operator.

You can't use a Join between a SQL source and a local source. You'll need to bring the SQL data into memory before you can join them. In this case, you're not really doing a join since you only take the elements from the first collection, what you want is a select...where...selectid in query, which you can get using the Contains method.
Translates to
where the values for the in clause come from the list of ids in the collection of local objects.
