屬性值

型別：System.Int32
針對 Stroke 物件收到的封包數目。

範例

在這個範例中，InkCollectorNewPacketsEventHandler 執行個體會取得透過 InkCollectorNewPacketsEventArgs 物件所傳遞最後一個封包的 X 和 Y 值。X 和 Y 值一定位於封包資料的前兩個位置。

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];

}
