The + operator is overloaded to do the same job:
using System;
using System.Text;
class Sample
{
public static void Main()
{
DateTime dt = new DateTime(2000, 2, 3, 10, 20, 30);
TimeSpan ts = TimeSpan.FromMinutes(90);
Console.WriteLine(dt.Add(ts));
Console.WriteLine(dt + ts);
}
}
The output:
2/3/2000 11:50:30 AM
2/3/2000 11:50:30 AM
