Member Function Documentation

GetTimestamp()

static long System.Diagnostics.Stopwatch.GetTimestamp ( )

static

Gets the current number of ticks in the timer mechanism.

Returns

A long integer representing the tick counter value of the underlying timer mechanism.

Definition at line 160 of file Stopwatch.cs.

Reset()

void System.Diagnostics.Stopwatch.Reset

(

)

Stops time interval measurement and resets the elapsed time to zero.

Definition at line 141 of file Stopwatch.cs.

Restart()

void System.Diagnostics.Stopwatch.Restart

(

)

Stops time interval measurement, resets the elapsed time to zero, and starts measuring elapsed time.

Definition at line 150 of file Stopwatch.cs.

Start()

void System.Diagnostics.Stopwatch.Start

(

)

Starts, or resumes, measuring elapsed time for an interval.

Definition at line 103 of file Stopwatch.cs.

StartNew()

static Stopwatch System.Diagnostics.Stopwatch.StartNew ( )

static

Initializes a new T:System.Diagnostics.Stopwatch instance, sets the elapsed time property to zero, and starts measuring elapsed time.

Returns

A T:System.Diagnostics.Stopwatch that has just begun measuring elapsed time.

Definition at line 115 of file Stopwatch.cs.

Stop()

void System.Diagnostics.Stopwatch.Stop

(

)

Stops measuring elapsed time for an interval.

Definition at line 124 of file Stopwatch.cs.

Member Data Documentation

Frequency

readonly long System.Diagnostics.Stopwatch.Frequency

static

Gets the frequency of the timer as the number of ticks per second. This field is read-only.

Definition at line 21 of file Stopwatch.cs.

IsHighResolution

readonly bool System.Diagnostics.Stopwatch.IsHighResolution

static

Indicates whether the timer is based on a high-resolution performance counter. This field is read-only.

Definition at line 25 of file Stopwatch.cs.

Property Documentation

Elapsed

TimeSpan System.Diagnostics.Stopwatch.Elapsed

get

Gets the total elapsed time measured by the current instance.

Returns

A read-only T:System.TimeSpan representing the total elapsed time measured by the current instance.

Definition at line 46 of file Stopwatch.cs.

ElapsedMilliseconds

long System.Diagnostics.Stopwatch.ElapsedMilliseconds

get

Gets the total elapsed time measured by the current instance, in milliseconds.

Returns

A read-only long integer representing the total number of milliseconds measured by the current instance.

Definition at line 58 of file Stopwatch.cs.

ElapsedTicks

long System.Diagnostics.Stopwatch.ElapsedTicks

get

Gets the total elapsed time measured by the current instance, in timer ticks.

Returns

A read-only long integer representing the total number of timer ticks measured by the current instance.

Definition at line 70 of file Stopwatch.cs.

IsRunning

bool System.Diagnostics.Stopwatch.IsRunning

get

Gets a value indicating whether the T:System.Diagnostics.Stopwatch timer is running.

Returns

true if the T:System.Diagnostics.Stopwatch instance is currently running and measuring elapsed time for an interval; otherwise, false.
