DateTime.Now.TimeOfDaygives it to you as a TimeSpan(from midnight).
DateTime.Now.TimeOfDay把它作为TimeSpan（从午夜）给你。
DateTime.Now.ToString("h:mm:ss tt")gives it to you as a string.
DateTime.Now.ToString("h:mm:ss tt")将其作为字符串提供给您。

Current time with AM/PM designator:
带有 AM/PM 指示符的当前时间：
DateTime.Now.ToString("hh:mm:ss tt", System.Globalization.DateTimeFormatInfo.InvariantInfo)
DateTime.Now.ToString("hh:mm:ss.fff tt", System.Globalization.DateTimeFormatInfo.InvariantInfo)
Current time using 0-23 hour notation:
使用 0-23 小时表示法的当前时间：
DateTime.Now.ToString("HH:mm:ss", System.Globalization.DateTimeFormatInfo.InvariantInfo)
DateTime.Now.ToString("HH:mm:ss.fff", System.Globalization.DateTimeFormatInfo.InvariantInfo)

This will show you only the current time, in 24 hour format:
这将仅以 24 小时格式显示当前时间：
class Program
{
static void Main(string[] args)
{
Console.WriteLine(DateTime.Now.ToLongTimeString().ToString());
Console.WriteLine(DateTime.Now.ToShortTimeString().ToString());
Console.ReadLine();
}
}

Try this one. Its working for me in 3tier Architecture Web Application.
试试这个。它在 3tier Architecture Web Application 中为我工作。
"'" + DateTime.Now.ToString() + "'"
Please remember the Single Quotes in the insert Query.
请记住插入查询中的单引号。
For example:
例如：
string Command = @"Insert Into CONFIG_USERS(smallint_empID,smallint_userID,str_username,str_pwd,str_secquestion,str_secanswer,tinyint_roleID,str_phone,str_email,Dt_createdOn,Dt_modifiedOn) values ("
+ u.Employees + ","
+ u.UserID + ",'"
+ u.Username + "','"
+ u.GetPassword() + "','"
+ u.SecQ + "','"
+ u.SecA + "',"
+ u.RoleID + ",'"
+ u.Phone + "','"
+ u.Email + "','"
+ DateTime.Now.ToString() + "','"
+ DateTime.Now.ToString() + "')";
The DateTimeinsertion at the end of the line.
的DateTime在该行的末端插入。
