推荐答案

AddHours方法获得double( Double.Parse [

AddHours method gets a double (MSDN[^]) as argument, hence you have to convert your string to a double value (try the Double.Parse[^] method).

从您的解释中，我可以得出这个答案.让我知道这是否适合.

Hi,

From your explanation, I could come up with this answer. Let me know if this suits.

DateTime startTime =Convert.ToDateTime(dttimeslot.Rows[0]["day_start_time"].ToString());
DateTime endTime=Convert.ToDateTime(dttimeslot.Rows[0]["day_end_time"].ToString());

while (startTime < endTime)
{
    startTime = startTime.AddMinutes(inc);
    //Your logic here
}

这有帮助吗?
