我认为您不能直接使用 PhoneGap 来完成,来自PhoneGap 常见问题解答
Q: Can you use PHP/ASP/JSF/Java/.NET with PhoneGap?
A: A PhoneGap application may only use HTML, CSS, and JavaScript.
However, you can make use of network protocols (XmlHTTPRequest, Web Sockets,
etc) to easily communicate with backend services written in any language.
This allows your PhoneGap app to remotely access existing business processes
while the device is connected to the Internet.
因此,如果您要走 PhoneGap 路线,则必须用 HTML/CSS/JavaScript 编写它。但是,如果您更熟悉 .NET 和 C#,那么总会有Xamarin Android,它有一个免费的入门版本供您试用。不过要意识到,如果你走这条路,它将是一个移动应用程序,而不是一个包装好的 ASP.NET 应用程序。
