将字符串值添加到日期时间 [英] Add string value into datetime

问题描述

大家好，

我的字符串是like("+ 5"或"-5").我想将其添加到日期时间"中.

即时间是01:20:20 PM和string ="+ 5"，那么输出将是:06:20:20 PM
时间是01:20:20 PM和string =-5"，那么输出将是:08:20:20 AM

建议我为此解决方案.

谢谢

推荐答案

使用TimeSpan类.

此处 [

Use the TimeSpan class.

Here[^] is more information on TimeSpan.Add method.

DateTime dt = DateTime.Now;
String s = "+5";    // or "-5" works with both + and -
dt  = dt.AddHours(Convert.ToInt32(s));

尝试一下:

Try this:

DateTime clientTime = System.Date.Now;
string hrsToCompute = "+5";
int final = 0;

if(hrsToCompute.IndexOf("+"))
{
   final = Convert.ToInt32(hrsToCompute.Substring(1));
   clientTime.AddHours(hours);
}
//same logic here for negative.....

问候，
