Linq to sql 此Sql查询的Linq到Sql等效项

到目前为止，我使用了连接的Id字符串，如

1,2,3

，并使用此查询在我的表中进行了更新

if exists( select ClientId from Clients where ClientId IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i))
    begin
        update Clients set IsDeleted=1 where ClientId IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i)
        select 'deleted' as message
    end

---

对于上述查询，linq到sql的等价物是什么？任何建议…

如果我已经理解了您试图正确执行的操作，类似的操作应该会奏效

var idsToDelete = ids.Split(",").Select(x => Convert.ToInt32(x));

var clientsToDelete = _DB.Clients.Where(x => idsToDelete.Contains(x.Id));

foreach(var client in clientsToDelete)
{
   client.IsDeleted = true;
}

_DB.SubmitChanges();
