示例1: Go
internal async Task Go(CancellationToken cancellationToken, CanvasDevice device, ScenarioData scenarioData)
{
var runner = MakeScenarioRunner();
scenarioData.AddDataToScenarioRunner(runner);
// Create the image source and the render target. These sizes are hardcoded and independent of the
// display's DPI since we just want a small image to convince ourselves that the scenarios really are
// rendering the right thing.
Image = new CanvasImageSource(device, 128, 128, 96);
using (var rt = new CanvasRenderTarget(device, 128, 128, 96))
{
// We actually run the scenario on the thread pool - XAML really falls down if you overload the UI thread.
var time = await Task.Run(() =>
{
// Run the scenario multiple times to try and avoid too much noise
List<CpuGpuTime> times = new List<CpuGpuTime>();
for (int i = 0; i < 10; ++i)
{
// Hold the device lock while we run the scenario - this prevents other threads
// from interacting with the device and interfering with our recorded time.
using (var deviceLock = device.Lock())
{
times.Add(RunScenario(runner, rt));
