C# “的最佳重载方法匹配”&引用；具有一些无效参数，可用于不同表上的同一查询

我在数据库中添加了一个新表，并更新了MSDModel

现在，我想用我已有的查询将该表中的新值显示给我的应用程序

我现在拥有的：

context.Load(context.GetScannerStatusHistoryQuery(selectedDetector.DetectorID, datePickerFrom.SelectedDate.Value, datePickerTo.SelectedDate.Value), TemperatureHistoryLoaded2, null);

[Query]
public IQueryable<ScannerStatusHistory> GetScannerStatusHistory(int detectorID, DateTimeOffset dateFrom, DateTimeOffset dateTo)
{
    return ObjectContext.ScannerStatusHistories.Where(t => t.DetectorID == detectorID && t.TimeStamp >= dateFrom && t.TimeStamp <= dateTo);
}

context.Load(context.GetTemperatureHistoryQuery(selectedDetector.DetectorID, datePickerFrom.SelectedDate.Value, datePickerTo.SelectedDate.Value), TemperatureHistoryLoaded2, null);

[Query]
public IQueryable<TemperatureHistory> GetTemperatureHistory(int detectorID, DateTimeOffset dateFrom, DateTimeOffset dateTo)
{
    return ObjectContext.TemperatureHistories.Where(t => t.DetectorID == detectorID && t.DateTime >= dateFrom && t.DateTime <= dateTo);
}

代码：

context.Load(context.GetScannerStatusHistoryQuery(selectedDetector.DetectorID, datePickerFrom.SelectedDate.Value, datePickerTo.SelectedDate.Value), TemperatureHistoryLoaded2, null);

[Query]
public IQueryable<ScannerStatusHistory> GetScannerStatusHistory(int detectorID, DateTimeOffset dateFrom, DateTimeOffset dateTo)
{
    return ObjectContext.ScannerStatusHistories.Where(t => t.DetectorID == detectorID && t.TimeStamp >= dateFrom && t.TimeStamp <= dateTo);
}

context.Load(context.GetTemperatureHistoryQuery(selectedDetector.DetectorID, datePickerFrom.SelectedDate.Value, datePickerTo.SelectedDate.Value), TemperatureHistoryLoaded2, null);

[Query]
public IQueryable<TemperatureHistory> GetTemperatureHistory(int detectorID, DateTimeOffset dateFrom, DateTimeOffset dateTo)
{
    return ObjectContext.TemperatureHistories.Where(t => t.DetectorID == detectorID && t.DateTime >= dateFrom && t.DateTime <= dateTo);
}

然后查询：

context.Load(context.GetScannerStatusHistoryQuery(selectedDetector.DetectorID, datePickerFrom.SelectedDate.Value, datePickerTo.SelectedDate.Value), TemperatureHistoryLoaded2, null);

[Query]
public IQueryable<ScannerStatusHistory> GetScannerStatusHistory(int detectorID, DateTimeOffset dateFrom, DateTimeOffset dateTo)
{
    return ObjectContext.ScannerStatusHistories.Where(t => t.DetectorID == detectorID && t.TimeStamp >= dateFrom && t.TimeStamp <= dateTo);
}

context.Load(context.GetTemperatureHistoryQuery(selectedDetector.DetectorID, datePickerFrom.SelectedDate.Value, datePickerTo.SelectedDate.Value), TemperatureHistoryLoaded2, null);

[Query]
public IQueryable<TemperatureHistory> GetTemperatureHistory(int detectorID, DateTimeOffset dateFrom, DateTimeOffset dateTo)
{
    return ObjectContext.TemperatureHistories.Where(t => t.DetectorID == detectorID && t.DateTime >= dateFrom && t.DateTime <= dateTo);
}

然后查询：

context.Load(context.GetScannerStatusHistoryQuery(selectedDetector.DetectorID, datePickerFrom.SelectedDate.Value, datePickerTo.SelectedDate.Value), TemperatureHistoryLoaded2, null);

[Query]
public IQueryable<ScannerStatusHistory> GetScannerStatusHistory(int detectorID, DateTimeOffset dateFrom, DateTimeOffset dateTo)
{
    return ObjectContext.ScannerStatusHistories.Where(t => t.DetectorID == detectorID && t.TimeStamp >= dateFrom && t.TimeStamp <= dateTo);
}

context.Load(context.GetTemperatureHistoryQuery(selectedDetector.DetectorID, datePickerFrom.SelectedDate.Value, datePickerTo.SelectedDate.Value), TemperatureHistoryLoaded2, null);

[Query]
public IQueryable<TemperatureHistory> GetTemperatureHistory(int detectorID, DateTimeOffset dateFrom, DateTimeOffset dateTo)
{
    return ObjectContext.TemperatureHistories.Where(t => t.DetectorID == detectorID && t.DateTime >= dateFrom && t.DateTime <= dateTo);
}

公共IQueryable GetTemperatureHistory（int-detectorID、DateTimeOffset-dateFrom、DateTimeOffset-dateTo）
{
返回ObjectContext.TemperatureHistories.Where（t=>t.DetectorID==DetectorID&&t.DateTime>=dateFrom&&t.DateTime为什么要从
DateTime
切换到
TimeStamp
？新表接收不同的数据。创建它的人添加了列TimeStamp。它的作用是相同的，只是名称不同。只是询问一下……因为它们在创建时使用了不同的语法Database仍然使用
DateTime
，MSSQL反应为“特殊”时间戳值。MySQL不接受日期或月份列中包含零的
时间戳
值或无效日期的值。TemperatureHistory DateTime包含如下值：2016-02-03 15:00:00.0000000+00:00，ScannerStatusHistory时间戳包含如下值：2017-01-06 14:40:40.0000000+01:00你能改用DateTime吗？
