linq to sql: join multiple columns from the same table

Question

How do I inner join multiple columns from the same tables via Linq?

For example: I already have this...

join c in db.table2 on table2.ID equals tab

You can put your query inside a Where clause instead of using the join operator.

The join operator supports multiple clauses in VB.NET, but not C#.

Alternatively, you can use the ANSI-82 style of 'SQL' syntax, e.g.:

from t1 in table1
from t2 in table1
where t1.x == t2.x
&& t1.y == t2.y
