linq和存储过程

我试图在LINQ中执行一个存储过程。在SQLServer中运行时，它返回多个字段，大多数是整数和浮点字段。但是当我在LINQ中调用存储过程时，它只返回0。下面是我调用存储过程的方式：

var meterReadings = _database.MetricDataReport("20101127");

下面是存储过程：

ALTER PROCEDURE [dbo].[MetricDataReport]
@FormDate VARCHAR(8)
AS
SET NOCOUNT ON  



/*Table To Hold Finished RecordSet*/
CREATE TABLE #OutputTable
(
    PkMetricMeterID INT,
    FkSiteID        INT,
    FourWeekReading FLOAT,
    LastWeekReading FLOAT,
    ThisWeekReading FLOAT,
    pkMeterID       INT,
    DecimalPlaces   INT

)

CREATE TABLE #WorkingTable
(
    PkMetricMeterID INT,
    FkSiteID        INT,
    FormDate        DATETIME,
    Reading         FLOAT,
    pkMeterID       INT,
    DecimalPlaces   INT
)

我对这方面的了解不够，看不出问题出在哪里，但您可能希望首先使用一个简单得多的存储过程来实现这一点。只返回一个简单列表的东西

另外，请看一下如何将存储过程与LINQtoSQL结合使用
