DateTime now = DateTime.Now; // Add 1 tick DateTime afterTick = now.AddTicks(1); // Add 1 second DateTime afterSeconds = now.AddTicks(TimeSpan.TicksPerSecond); // Add 1 minute and 30 seconds TimeSpan timeToAdd = new TimeSpan(0, 1, 30); DateTime afterTime = now.AddTicks(timeToAdd.Ticks);In these examples, we use the AddTicks method to add a single tick, 1 second, and 1 minute and 30 seconds to a DateTime instance, respectively. The AddTicks method is part of the System.DateTime struct in the .NET Framework class library.
