Question

I am trying to work out how to covert the script below from SQL in to LINQ. Any help would be welcome.

SELECT *
FROM
    [tableName]
WHERE
[MyDate] IN
    (SELECT
        MAX([MyDate])
   FROM
      [tableName]
   GROUP BY
      [MyID])

I can’t find an equivalent for the “IN” clause section. There are existing questions on this forum but none that cover selecting a DateTime.

Thanks in advance.

I think Any() is what you are looking for:

var result = tableName.Where(x => 
                (from t in tableName
                group t by t.MyID into g
                where g.Max(y => y.MyDate) == x.MyDate
                select 1).Any())
