DateTime型日期的运算

[boyhu88]

已经有两DateTime型数据DT1（2006/04/24 17:13:26)和DT2（2006/06/21 01:01:01)

合成一个DT3（2006/04/24 01:01:01)，即取DT1的日期段及取DT2的时间段，谢谢

string str1 = dt1.toString("yyyy/MM/dd");
string str2 = dt2.toString("hh:mm:ss");

string str3 = st1 + " " + str2;

DateTime dt3 = DateTime.parse(str3);

[qyfjl]

DateTime dt1 = new DateTime();
dt1 = Convert.ToDateTime("2006/04/24 17:13:26");
DateTime dt2 = new DateTime();
dt2 = Convert.ToDateTime("2006/06/21 01:01:01");
DateTime dt3 = new DateTime();
dt3 =Convert.ToDateTime (dt1.ToShortDateString () +" "+ dt2.ToShortTimeString ());
MessageBox.Show(dt3.ToString ());

[从不签到]

DateTime dt1 = Convert.ToDateTime(TextBox1.Text);
DateTime dt2 = Convert.ToDateTime(TextBox2.Text);
TextBox3.Text = dt1.ToShortDateString() + " " + dt2.ToLongTimeString();

Dim d1 As Date = #4/24/2006 5:13:26 PM#
Dim d2 As Date = #6/21/2006 1:01:01 AM#
Dim d3 As Date = Nothing
d3 = d1.Date + d2.TimeOfDay
MsgBox(d3.ToString)

用substring(表達式,起始位置,長度)

谢谢各位的解答，hhjjhjhj(大头)的解答我试过有错误，是否要Imports什么命名空间，采用的是qyfjl() 的方法

hhjjhjhj(大头)的才是标准的 .Net 用法
