TimesSelector
Inspired from ye good old ruby on rails, provides you with new DateTime instances based on an integer you provide. Look at realfiction.net -> extension methods for more detail

public abstract class TimeSelector {
protected TimeSpan myTimeSpan;
internal int ReferenceValue {
set { myTimeSpan = MyTimeSpan(value); }
}
public DateTime Ago { get { return DateTime.Now - myTimeSpan; } }
public DateTime FromNow { get { return DateTime.Now + myTimeSpan; } }
public DateTime AgoSince(DateTime dt) { return dt - myTimeSpan; }
public DateTime From(DateTime dt) { return dt + myTimeSpan; }
protected abstract TimeSpan MyTimeSpan(int refValue);
}
public class WeekSelector : TimeSelector {
protected override TimeSpan MyTimeSpan(int refValue) { return new TimeSpan(7 * refValue, 0, 0, 0); }
}
public class DaysSelector : TimeSelector {
protected override TimeSpan MyTimeSpan(int refValue) { return new TimeSpan(refValue, 0, 0, 0); }
}
public class YearsSelector : TimeSelector {
protected override TimeSpan MyTimeSpan(int refValue) {
return new TimeSpan(365 * refValue, 0, 0, 0);
}
}
public static class Extensions {
public static WeekSelector Weeks(this int value) {
var ws = new WeekSelector();
ws.ReferenceValue = value;
return ws;
}
public static YearsSelector Years(this int value) {
var ws = new YearsSelector();
ws.ReferenceValue = value;
return ws;
}
public static DaysSelector Days(this int value) {
var ws = new DaysSelector();
ws.ReferenceValue = value;
return ws;
}
}Example
Console.WriteLine(3.Weeks().Ago);
Console.WriteLine(5.Years().FromNow);
Console.WriteLine(19.Days().From(new DateTime(2007,1,1)));
