Public ReadOnly Property PacketCount As Integer
用法
Dim instance As InkCollectorNewPacketsEventArgs
Dim value As Integer

value = instance.PacketCount

public int PacketCount { get; }

public:
property int PacketCount {
    int get ();
}

/** @property */

属性值

类型：System.Int32
为 Stroke 对象收到的数据包的数目。

示例

在此示例中，InkCollectorNewPacketsEventHandler 实例获取通过 InkCollectorNewPacketsEventArgs 对象传递的最后一个数据包的 X 和 Y 值。X 和 Y 值总是位于数据包数据的前两个位置。

Private Sub mInkObject_NewPackets2(ByVal sender As Object, ByVal e As InkCollectorNewPacketsEventArgs)
    Dim DescriptorsPerPacket As Integer = e.Stroke.PacketDescription.Length
    Dim LastX As Integer = e.PacketData(DescriptorsPerPacket * (e.PacketCount - 1))
    Dim LastY As Integer = e.PacketData((DescriptorsPerPacket * (e.PacketCount - 1)) + 1)
End Sub

private void mInkObject_NewPackets2(object sender, InkCollectorNewPacketsEventArgs e)
{

    int DescriptorsPerPacket = e.Stroke.PacketDescription.Length;
    int LastX = e.PacketData[DescriptorsPerPacket * (e.PacketCount - 1)];
    int LastY = e.PacketData[(DescriptorsPerPacket * (e.PacketCount - 1)) + 1];

}
