I want
我想要
MyNewDateValue = MyDateNow - MyDateInteger;
Example Today is the 22nd of December 2012
示例 今天是 2012 年 12 月 22 日
If MyDateIneger value is 120, MyNewDateValue, will return the datetime 120 days ago.
如果 MyDateIneger 值为 120，则 MyNewDateValue 将返回 120 天前的日期时间。

MyNewDateValue = MyDateNow.AddDays(-120);
or
或者
MyNewDateValue = MyDateNow.AddDays(myVar);
回答by pala?н
Please look into DateTime.AddDaysmethod
请查看DateTime.AddDays方法
DateTime oneTwentyDaysAgo = DateTime.Today.AddDays(-120);
or in general
或一般
DateTime nDaysAgo = DateTime.Today.AddDays(-N);
// where N is the number of days

Try this frnd
试试这个
DateTime dt = new DateTime();
dt = DateTime.Now;
DateTime newdt = new DateTime();
TimeSpan tim = new TimeSpan(120,0,0,0,0);
newdt = dt.Add(tim);
MessageBox.Show(newdt.ToString());
ADD.timespan will help you to add or subtract days from today.
ADD.timespan 将帮助您从今天开始增加或减少天数。
