PerceptionControlSession.TrySetPropertyAsync(String, Object) 方法

定義

命名空間:

Windows.Devices.Perception

建立屬性變更要求。 此要求會以非同步方式處理，而且不保證會成功。 應該檢查屬性變更結果，以判斷是否實際接受屬性變更，如果不是，則表示屬性變更不受接受的原因。

public:
 virtual IAsyncOperation<PerceptionFrameSourcePropertyChangeResult ^> ^ TrySetPropertyAsync(Platform::String ^ name, Platform::Object ^ value) = TrySetPropertyAsync;

function trySetPropertyAsync(name, value)

Public Function TrySetPropertyAsync (name As String, value As Object) As IAsyncOperation(Of PerceptionFrameSourcePropertyChangeResult)

參數

name

winrt::hstring

要變更的屬性名稱。

value

Object

Platform::Object

IInspectable

新的屬性值。

傳回
