Gets the number of milliseconds elapsed since the system started.
Public Shared ReadOnly Property TickCount As Integer
public static int TickCount { get; }
public: static property int TickCount { int get (); }
static member TickCount : int
The value of this property is derived from the system timer and is stored as a 32-bit signed integer. Consequently, if the system runs continuously, TickCount will increment from zero to Int32..::.MaxValue for approximately 24.9 days, then jump to Int32..::.MinValue, which is a negative number, then increment back to zero during the next 24.9 days.
TickCount is different from the Ticks property, which is the number of 100-nanosecond intervals that have elapsed since 1/1/0001, 12:00am.
Use the DateTime..::.Now property to obtain the current local date and time on this computer.
The following example demonstrates how to retrieve the positive range of values returned by the TickCount property. The TickCount property cycles between Int32..::.MinValue, which is a negative number, and Int32..::.MaxValue once every 49.8 days. This code sample removes the sign bit to yield a nonnegative number that cycles between zero and MaxValue once every 24.9 days.
