Answer 1

以下代码可能会帮助您:

var dueDate = new DateTime(2011, 3, 3);

//if you want to increment six days
var dueDatePlus6Days = dueDate.AddDays(6);

//if you want to increment six months
var dueDatePlus6Months = dueDate.AddMonths(6);

var daysDiff1 = (dueDatePlus6Days - dueDate).TotalDays; //gives 6
var daysDiff2 = (dueDatePlus6Months - dueDate).TotalDays; //gives 184
