我有一个数据库，存储来自用户的彩票表单提交。其中一列是每当有人提交表单时用当前日期时间填充的DateTime列。我希望能够通过DateTime列进行搜索，这样我就可以提取在特定日期输入的所有表单。DateTime搜索问题ASP.NET
我在执行搜索时没有收到任何错误，只是我的自定义消息“没有符合该搜索条件的结果”。我试过禁用jquery datepicker，并尝试从数据库复制并粘贴确切的DateTime字段到搜索框中，仍然没有。显然我错过了一些东西，但我无法弄清楚什么。任何帮助深表感谢。

我认为你必须创建可以看着用于复制问题上最小的样品。 –
*您可能*您的专栏有一个时间部分，您不是因素分解 - 您不能将datepicker日期（可能解析为'YYYY-MM-DDT00：00：00'）等同于'DATETIME'包含时间的列（'YYYY-MM-DDTHH：MM：SS'）。您可能需要将您的搜索SQL更改为WHERE dateTime> = @ date1和dateTime <@ date2'，并将'Date1'作为DateTime.Parse（datesearch.Text）.Date'和'@ date2'作为DateTime .Parse（datesearch.Text）.Date.AddDays（1）'在选定日期内切断时间部分和范围搜索。 – jimbobmcgee
谢谢jimbobmcgee，那就是诀窍。尽管我确信西格蒙的答案也能奏效。我刚刚尝试过你。 – HiCntry
