代码示例如下，从事这方面的可以参考下，下面是代码：
void SDKSample::DeviceCaps::Touch::TouchGetSettings_Click(Platform::Object^ sender, Windows::UI::Xaml::RoutedEventArgs^ e)
{
Button^ b = safe_cast<Button^>(sender);
if (b != nullptr)
{
TouchCapabilities^ pTouchCapabilities = ref new TouchCapabilities();
Platform::String^ Buffer;

Buffer = "There is " + (pTouchCapabilities->TouchPresent != 0 ? "a" : "no") + "
digitizer present\n";
Buffer += "The digitizer supports " + pTouchCapabilities->Contacts.ToString() + "
contacts\n";

TouchOutputTextBlock->Text = Buffer;
}
}
