Tsql linq到sql将日期合并到组中

我有一个简单的sql查询，如下所示：

SELECT dt AS 'startDate'
 , dt AS 'endDate'
FROM
    WorkCalendar
WHERE
     dt BETWEEN dateadd(yy, datediff(yy, 0, getdate()), 0) AND dateadd(MILLISECOND, -3, dateadd(YEAR, datediff(YEAR, 0, getdate()) + 1, 0))
     AND isWorkDay = 0

这将返回“我的表”中的所有日期，其中包含当前年度的空闲天数

这是示例输出：

startDate               endDate
2012-01-01 00:00:00     2012-01-01 00:00:00
2012-01-06 00:00:00     2012-01-06 00:00:00
2012-01-07 00:00:00     2012-01-07 00:00:00
2012-01-08 00:00:00     2012-01-08 00:00:00
2012-01-14 00:00:00     2012-01-14 00:00:00
2012-01-15 00:00:00     2012-01-15 00:00:00
2012-01-21 00:00:00     2012-01-21 00:00:00
2012-01-22 00:00:00     2012-01-22 00:00:00

我想做的是将临近日期分组如下：

startDate               endDate
2012-01-01 00:00:00     2012-01-01 00:00:00
2012-01-06 00:00:00     2012-01-08 00:00:00
2012-01-14 00:00:00     2012-01-15 00:00:00
2012-01-21 00:00:00     2012-01-22 00:00:00

如果我有两天或两天以上的时间，我想加入他们的小组

我希望使用linq to sql完成这项工作，因为在webservice中使用它会更简单，但简单的sql可以做到这一点：）

得到如下结果：

WITH d (d1) 
 AS (SELECT dt 
     FROM   workcalendar 
     WHERE  dt BETWEEN Dateadd(yy, Datediff(yy, 0, Getdate()), 0) AND 
                               Dateadd(millisecond, -3, 
                               Dateadd(year, Datediff(year, 
                                             0, 
                                             Getdate()) + 1 
                               , 0)) 
            AND isworkday = 0) 
SELECT Z1.d1 AS startDate, 
   Z2.d1 AS endDate 
FROM   (SELECT Row_number() 
             OVER ( 
               ORDER BY A.d1) AS 'ID', 
           A.d1 
    FROM   d AS A 
    WHERE  NOT EXISTS (SELECT * 
                       FROM   d AS C 
                       WHERE  A.d1 = Dateadd(d, 1, C.d1))) AS Z1, 
   (SELECT Row_number() 
             OVER ( 
               ORDER BY A.d1) AS 'ID', 
           A.d1 
    FROM   d AS A 
    WHERE  NOT EXISTS (SELECT * 
                       FROM   d AS C 
                       WHERE  A.d1 = Dateadd(d, -1, C.d1))) AS Z2 
WHERE  Z1.id = Z2.id

但是欢迎任何评论和优化：）

您已经尝试过了什么？现在我正在使用第一部分，但我尝试过构建递归查询，但我已经停止了我的服务器在endDate+1=startDate进行连接：/能否向我们展示LINQ到SQL查询您已经编写了？我只有SQL查询。我以为您正在寻找LINQ to SQL来表达这一点？是的，但不知道如何转换：/
