你可能做不到.用户控件不具备页面的所有功能，不能直接调用.相反，您应该创建一个 Web 服务 (asmx) 来处理这种情况.如果您愿意，可以将 Web 服务调用路由到您的用户控件内的静态方法.

You probably can't. The user control doesn't have all the functionality of a page and can't be called directly. You should instead create a webservice (asmx) to handle this scenario. If you wanted, the webservice call could be routed to the static method inside your user control.
