Windows.Media.Capture

重载

CaptureAsync()	异步执行高级照片捕获。
CaptureAsync(Object)	异步执行高级照片捕获，将提供的应用定义的上下文对象传递给操作的结果。

CaptureAsync()

异步执行高级照片捕获。

public:
 virtual IAsyncOperation<AdvancedCapturedPhoto ^> ^ CaptureAsync() = CaptureAsync;

/// [Windows.Foundation.Metadata.Overload("CaptureAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<AdvancedCapturedPhoto> CaptureAsync();

[Windows.Foundation.Metadata.Overload("CaptureAsync")]
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<AdvancedCapturedPhoto> CaptureAsync();

function captureAsync()

Public Function CaptureAsync () As IAsyncOperation(Of AdvancedCapturedPhoto)

返回

IAsyncOperation<AdvancedCapturedPhoto>

成功完成后返回 AdvancedCapturedPhoto 的 异步操作。

属性

OverloadAttribute RemoteAsyncAttribute

注解

在调用 CaptureAsync 之前，必须调用 MediaCapture.PrepareAdvancedPhotoCaptureAsync。
