示例1: NativeDiskDisappeared
private void NativeDiskDisappeared(IntPtr disk, IntPtr context)
{
if (this.DeviceDisappeared == null) {
// if no-one subscribed to this event, do nothing
return;
}
IntPtr device = DiskArbitration.DADiskCopyIOMedia (disk);
IntPtr propertiesRef = DiskArbitration.DADiskCopyDescription (disk);
NSDictionary properties = new NSDictionary (propertiesRef);
DeviceArguments deviceArguments = new DeviceArguments (properties, this);
if (properties.HasKey ("DADeviceProtocol") && properties.GetStringValue ("DADeviceProtocol") == "USB") {
OsxUsbData usb = new OsxUsbData (device);
deviceArguments.UsbInfo = usb;
}
IOKit.IOObjectRelease (device);
this.DeviceDisappeared (this, deviceArguments);
GC.KeepAlive (this);
}示例2: NativeDiskChanged
private void NativeDiskChanged(IntPtr disk, IntPtr keys, IntPtr context)
{
if (this.DeviceChanged == null) {
// if no-one subscribed to this event, do nothing
return;
}
IntPtr device = DiskArbitration.DADiskCopyIOMedia (disk);
IntPtr propertiesRef = DiskArbitration.DADiskCopyDescription (disk);
// using MonoMac we can get a managed NSDictionary from the pointer
NSDictionary properties = new NSDictionary (propertiesRef);
DeviceArguments deviceArguments = new DeviceArguments (properties, this);
if (properties.HasKey ("DADeviceProtocol") && properties.GetStringValue ("DADeviceProtocol") == "USB") {
OsxUsbData usb = new OsxUsbData (device);
deviceArguments.UsbInfo = usb;
}
IOKit.IOObjectRelease (device);
// trigger the public event for any subscribers
this.DeviceChanged (this, deviceArguments);
GC.KeepAlive (this);
}
