推荐答案

这样简单的事情怎么样：

How about something simple like this:

if ((ds.tables("che").rows(0).item("time") >= "01/01/1900 06:00") and (ds.tables("che").rows(0).item("time") <= "01/01/1900 08:00")) then

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            DateTime dt_table = DateTime.Now;

            Console.WriteLine(dt_table);

            DateTime dt_compare_1 = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 12, 0, 0);
            DateTime dt_compare_2 = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 1, 0, 0);

            if (dt_table > dt_compare_1 && dt_table < dt_compare_2)
                Console.WriteLine("Time is between 11 and 12 o''clock");
            else
                Console.WriteLine("Time is not between 11 and 12 o''clock");

            Console.ReadKey();
        }
    }
}

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            DateTime dt_table = DateTime.Now;

            Console.WriteLine(dt_table);

            DateTime dt_compare_1 = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 12, 0, 0);
            DateTime dt_compare_2 = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 1, 0, 0);

            if (dt_table > dt_compare_1 && dt_table < dt_compare_2)
                Console.WriteLine("Time is between 11 and 12 o'clock");
            else
                Console.WriteLine("Time is not between 11 and 12 o'clock");

            Console.ReadKey();
        }
    }
}
