C# / .NET - add year to DateTime

In C# / .NET it is possible to add years to date in following way.

DateTime.AddYears method example

DateTime time1 = new DateTime(2000, 1, 1, 12, 00, 00, 500);
DateTime time2 = time1.AddYears(10);

Console.WriteLine("Time before: " + time1.ToString("o"));
Console.WriteLine("Time after: " + time2.ToString("o"));

Output:

Time before: 2000-01-01T12:00:00.5000000
Time after: 2010-01-01T12:00:00.5000000
