vs2005里怎样取得本月的第一时间？
DateTime _begin = new DateTime();
_begin = ？？？？？？(此处为提问的)
DateTime _end = new DateTime();
_end = DateTime.Now;
因为我在SQL里要用到
between @begin and @end
(例如between '2007-07-01 ' and '2007-07-5 ')
这样的语句
所以我要取到本月的一天的，零点零分零秒也能取到最好了．谢谢了

[解决办法]
string MyString = "Jan 1, 2002 ";
DateTime MyDateTime = DateTime.Parse(MyString);

[解决办法]
int year = DateTime.Now.Year;
int month = DateTime.Now.Month;
DateTime dt = new DateTime(year, month, 1);
[解决办法]
DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + "1 "
