QuestionHow do I use this class Pin

I found this class on a forum...

How do I use it - I can't seem to callthe Difference method in bold text?
I'm currently trying...

DateDiff dateDiff = new DateDiff();
dateDiff.Difference((DateTime)StartDate, (DateTime)EndDate); // Doesn't Work

Many thanks for any help.

public class DateDiff
{
private int _Years = 0;
private int _Months = 0;
private int _Weeks = 0;
private int _Days = 0;
private int _Hours = 0;
private int _Minutes = 0;
private int _Seconds = 0;
public int Years { get { return _Years; } }
public int Months { get { return _Months; } }
public int Weeks { get { return _Weeks; } }
public int Days { get { return _Days; } }
public int Hours { get { return _Hours; } }
public int Minutes { get { return _Minutes; } }
public int Seconds { get { return _Seconds; } }

public override string ToString()
{
return String.Format("{0} year{1}, {2} month{3}, {4} week{5}, {6} day{7}, {8} hour{9}, {10} minute{11}, {12} second{13}"
, Years, Years != 1 ? "s" : ""
