LINQ to SQL každý N-tý řádek z tabulky

Někdy je TSQL správnou cestou. Použil bych ExecuteQuery<T> zde:

    var data = db.ExecuteQuery<SomeObjectType>(@"
SELECT * FROM 
(SELECT *, ROW_NUMBER() OVER (ORDER BY id) AS [__row]
FROM [YourTable]) x WHERE (x.__row % 25) = 1");

Můžete také vyměnit n :

    var data = db.ExecuteQuery<SomeObjectType>(@"
DECLARE @n int = 2
SELECT * FROM 
(SELECT *, ROW_NUMBER() OVER (ORDER BY id) AS [__row]
FROM [YourTable]) x WHERE (x.__row % @n) = 1", n);
