在c#中开发类似应用程序的iTunes

Question

我需要在c#中开发一个应用程序,它可以在连接到系统时自动检测iPhone并读取iPhone文件系统的特定文件.我基本上希望将此文件从设备自动下载到PC.我使用USBpcap工具表明iTunes使用某种XML格式连接到手机.任何帮助或见解非常感谢.是否有任何可以让我入门的第三方API文档？有些应用程序可以复制iTunes功能,例如Copytrans

是否有Apple提供的协议或API？

我一直在挖掘互联网,发现这个链接为iPhone分层通信.此外,我使用LibUsbDotNet库与USB设备进行通信(示例).任何人都可以建议应该使用哪个EndPoints.

在我看来,我必须在Windows应用程序中实现usbmuxd.它是一种多层协议.必须有一些库实现usbmuxd(我不认为我必须自己实现协议)

我对iTunes通信以及USB通信都不太了解.我正在尽可能多地添加信息(当然还有我在研发中提出的内容).任何帮助都非常感谢.

我一直在尝试向iPhone发送hello数据包字节,但我无法从手机中读取任何响应.
