position - 尝试跟踪 Kinect 关节时，“对非共享成员的引用需要对象引用”

Question

我想从 Kinect 跟踪关节位置（LeftKnee）。问题是我reference to a non-shared member requires an object reference参与Skeleton.Joints其中。任何人都可以帮助我吗？

Private Sub SensorSkeletonFrameReady(ByVal sender As Object, ByVal e As SkeletonFrameReadyEventArgs)
    Dim skeletons(-1) As Skeleton
    Using skeletonFrame As SkeletonFrame = e.OpenSkeletonFrame()
        If skeletonFrame IsNot Nothing Then
            skeletons = New Skeleton(skeletonFrame.SkeletonArrayLength - 1) {}
            skeletonFrame.CopySkeletonDataTo(skeletons)
            Dim j As Joint = Skeleton.Joints(JointType.LeftKnee)
        End If
    End Using

Answer 1

您JointType错误地引用了枚举。有关可能的枚举值的列表，请参阅 MSDN 上的JointType Enumeration 文档。

是JointType.KneeLeft，不是“左膝”。
