定義

命名空間:

Windows.UI.Xaml.Media

處置 LoadedImageSurface 和相關聯的資源。

public:
 virtual void Close() = Close;

void Close();

// This member is not implemented in C#

範例

在此範例中，即使LoadedImageSurface已關閉，CompositionSurfaceBrush仍會繼續存在。

Compositor compositor = new Compositor();
CompositionSurfaceBrush imageBrush = compositor.CreateSurfaceBrush();

LoadedImageSurface loadedSurface = LoadedImageSurface.StartLoadFromUri(new Uri("ms-appx:///Assets/myPic.jpg"));
loadedSurface.LoadCompleted += Load_Completed;
imageBrush.Surface = loadedSurface;

loadedSurface.Close();
// The imageBrush still exists

備註

呼叫這個方法將會處置 LoadedImageSurface 參考，不過除非您明確處置這些參照，否則從 LoadedImageSurface 建立的任何筆刷或表面仍會繼續轉譯。
