Question

我想连接到SQL数据库并根据包含年份和月份以及日期和时间的日期过滤我的记录。

我可以显示最后一天早上7点到系统日期之间的所有记录，但我想创建按钮作为名称作为过滤，并将两个文本框作为名称作为开始日期和结束日期。

您需要将日期转换为MM/dd/yyyy HH:mm格式并获取数据库中的记录

DataRow[] TempRow = Table.Select("((Entry_Time) >= #" + 
      StartDate.ToString("MM/dd/yyyy HH:mm", System.Globalization.CultureInfo.InvariantCulture) + "#) AND ((Entry_Time)<=#" +
      EndDate.ToString("MM/dd/yyyy HH:mm", System.Globalization.CultureInfo.InvariantCulture) + "#)");

获取两个日期之间的记录
