C# 在C中获得奇怪的值

在存储过程中获取完全正确的数据。但当我试图在C数据表中获取该值时，得到的数据是错误的。我不知道为什么我会这样

以下是我的存储过程：

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[GetSurveyStatistic]
    (@SurveyID int,
     @NameOfSubmitter varchar(200),
     @NameOfPrivacyContact varchar(200),
     @HspOrganizationalName varchar(200),
     @HspSiteNumber varchar(200),
     @FromDate datetime,
     @ToDate datetime,
     @weekly bit)
AS
BEGIN
    IF (@ToDate IS NOT NULL) 
        SET @ToDate = DATEADD(DAY, 1, @ToDate)

    IF @Weekly = 0 
    BEGIN
        SELECT
            CAST(CAST(StartedDateTime AS date) AS varchar(10)) Value, 
            COUNT(*) cnt
        FROM
            SubmittedSurveys
        WHERE
            (SurveyID = @SurveyID OR @SurveyID IS NULL)
            AND (StartedDateTime >= @FromDate OR @FromDate IS NULL)
            AND (StartedDateTime <= @ToDate OR @ToDate IS NULL)
            AND (LOWER(ProvidedNameOfSubmitter) LIKE LOWER(@NameOfSubmitter) + '%' 
                 OR @NameOfSubmitter IS NULL OR @NameOfSubmitter = '')
            AND (LOWER(NameOfPrivacyContact) LIKE LOWER(@NameOfPrivacyContact) + '%' 
                 OR @NameOfPrivacyContact IS NULL
                 OR @NameOfPrivacyContact = '')
            AND (LOWER(HspOrganizationalName) LIKE LOWER(@HspOrganizationalName) + '%'  
                 OR @HspOrganizationalName IS NULL
                 OR @HspOrganizationalName = '')
            AND (LOWER(HspSiteNumber) LIKE LOWER(@HspSiteNumber) 
                 OR @HspSiteNumber IS NULL OR @HspSiteNumber = '')
        GROUP BY
            CAST(StartedDateTime AS date)
        ORDER BY 
            1
    END
    ELSE BEGIN
        SELECT
            CAST(DATEPART(WEEK, StartedDateTime) AS varchar(10)) Value, 
            COUNT(*) cnt
        FROM
            SubmittedSurveys
        WHERE
            (SurveyID = @SurveyID OR @SurveyID IS NULL)
            AND (StartedDateTime >= @FromDate OR @FromDate IS NULL)
            AND (StartedDateTime <= @ToDate OR @ToDate IS NULL)
            AND (LOWER(ProvidedNameOfSubmitter) LIKE LOWER(@NameOfSubmitter) + '%' 
                 OR @NameOfSubmitter IS NULL OR @NameOfSubmitter = '')
            AND (LOWER(NameOfPrivacyContact) LIKE LOWER(@NameOfPrivacyContact) + '%' 
                 OR @NameOfPrivacyContact IS NULL
                 OR @NameOfPrivacyContact = '')
            AND (LOWER(HspOrganizationalName) LIKE LOWER(@HspOrganizationalName) + '%'  
                 OR @HspOrganizationalName IS NULL
                 OR @HspOrganizationalName = '')
            AND (LOWER(HspSiteNumber) LIKE LOWER(@HspSiteNumber) 
                 OR @HspSiteNumber IS NULL OR @HspSiteNumber = '')
        GROUP BY
            CAST(DATEPART(WEEK, StartedDateTime) AS varchar(10))
        ORDER BY 
            1
    END
END

下面是结果

但在前端，获取值=日期，而不是周值

这是前端的代码

public static List<SubmittedSurveys> GetSurveyStatistic(int SubmittedSurveyId, DateTime                 
     StartedDateTime, string NameOfSubmitter, string NameOfPrivacyContact, string 
     HspOrganizationalName, string HspSiteNumber,
     DateTime CompletedDateTime,bool weekly)
{
     try
     {
         DatabaseProviderFactory factory = new DatabaseProviderFactory();
         Database _wohcDB = factory.Create("SurveyToolDBEntities");
         // SqlDatabase _wohcDB = DatabaseFactory.CreateDatabase("SurveyToolDBEntities") as 
      SqlDatabase;

         string sqlCommand = "[GetSurveyStatistic]";

         DbCommand dbCommand = _wohcDB.GetStoredProcCommand(sqlCommand);

         _wohcDB.AddInParameter(dbCommand, "@SurveyID", DbType.Int32, SubmittedSurveyId);
         _wohcDB.AddInParameter(dbCommand, "@FromDate", DbType.DateTime, StartedDateTime);
         _wohcDB.AddInParameter(dbCommand, "@ToDate", DbType.DateTime, CompletedDateTime);
         _wohcDB.AddInParameter(dbCommand, "@NameOfSubmitter", DbType.String, NameOfSubmitter);
         _wohcDB.AddInParameter(dbCommand, "@NameOfPrivacyContact", DbType.String, NameOfPrivacyContact);
         _wohcDB.AddInParameter(dbCommand, "@HspOrganizationalName", DbType.String, HspOrganizationalName);
         _wohcDB.AddInParameter(dbCommand, "@HspSiteNumber", DbType.String, HspSiteNumber);
         _wohcDB.AddInParameter(dbCommand, "@weekly", DbType.String, weekly);

         DataSet ds = _wohcDB.ExecuteDataSet(dbCommand);

         _submittedSurvey = ReportsController.DbConverter.DataTable2List<SubmittedSurveys>(ds.Tables[0]);
         //_submittedSurvey[0].SurveyReports = ReportsController.DbConverter.DataTable2List<Reports>(ds.Tables[1]);
    }
    catch (Exception ex)
    {
        string message = ex.Message.ToString();
    }

    return _submittedSurvey;
}

这是前端的屏幕截图，我将错误的值作为日期而不是周

有人能帮我解决这个问题吗。这太奇怪了。我也尝试在int中强制转换，但得到的错误是日期不能转换为int。我不确定为什么我在前端得到错误的数据，在后端得到正确的数据

请帮助我。

尝试更改：

   _wohcDB.AddInParameter(dbCommand, "@weekly", DbType.String, weekly);

只要运行else部分，它就会正常工作。由于@Weekly=0，此查询将始终转到if语句。

Weekly的确切值是多少？不要猜测。为什么要将DbType.String用作布尔/位？周值为53。我正在将周转换为nvarchar10。这就是为什么我在前端使用字符串。要获得53作为字符串，我指的是_wohcDB.AddInParameterdbCommand，@weekly，DbType.String，weekly；。周值是53不，不是。它的数据类型是bool bool weekly。我会再问一次-weekly的C布尔值是多少？是的，在我的例子中是这样的。正如你所说，我运行else部分只删除if-else语句。非常感谢。这只是因为你传递了错误的每周值才起作用。

   _wohcDB.AddInParameter(dbCommand, "@weekly", DbType.Boolean, weekly);
