Ibland är TSQL rätt väg att gå. Jag skulle använda ExecuteQuery<T>
här:
var data = db.ExecuteQuery<SomeObjectType>(@"
SELECT * FROM
(SELECT *, ROW_NUMBER() OVER (ORDER BY id) AS [__row]
FROM [YourTable]) x WHERE (x.__row % 25) = 1");
Du kan också byta ut 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);
