c# - 使用 LINQ to SQL 匹配特定日期的所有行

Question

如何在表格中找到时间与特定日期匹配的所有行？

Time 列的 SQL 数据类型是 datetime。

例如，假设您想要 2014 年 9 月 20 日的所有行并且表列 Time 如下所示...2014-09-20 17:02:05.903

var query = from t in SomeTable
            where t.Time // don't know what goes here
            select t;

你可以试试这样的:

// Define your startDate. In our case it would be 9/20/2014 00:00:00
DateTime startDate = new DateTime(2014,09,20);

// Define your endDate. In our case it would be 9/21/2014 00:00:00
DateTime endDate = startDate.AddDays(1);

// Get all the rows of SomeTable, whose Time is between startDate and endDate.
var query = from t in SomeTable
            where t.Time>= startDate and t.Time<=endDate
            select t;
