我有一個數據庫，存儲來自用戶的彩票表單提交。其中一列是每當有人提交表單時用當前日期時間填充的DateTime列。我希望能夠通過DateTime列進行搜索，這樣我就可以提取在特定日期輸入的所有表單。DateTime搜索問題ASP.NET
我在執行搜索時沒有收到任何錯誤，只是我的自定義消息「沒有符合該搜索條件的結果」。我試過禁用jquery datepicker，並嘗試從數據庫複製並粘貼確切的DateTime字段到搜索框中，仍然沒有。顯然我錯過了一些東西，但我無法弄清楚什麼。任何幫助深表感謝。

我認爲你必須創建可以看着用於複製問題上最小的樣品。 –
*您可能*您的專欄有一個時間部分，您不是因素分解 - 您不能將datepicker日期（可能解析爲'YYYY-MM-DDT00：00：00'）等同於'DATETIME'包含時間的列（'YYYY-MM-DDTHH：MM：SS'）。您可能需要將您的搜索SQL更改爲WHERE dateTime> = @ date1和dateTime <@ date2'，並將'Date1'作爲DateTime.Parse（datesearch.Text）.Date'和'@ date2'作爲DateTime .Parse（datesearch.Text）.Date.AddDays（1）'在選定日期內切斷時間部分和範圍搜索。 – jimbobmcgee
謝謝jimbobmcgee，那就是訣竅。儘管我確信西格蒙的答案也能奏效。我剛剛嘗試過你。 – HiCntry
