Main 是 static 但是调用的是 Bar 。这是行不通的。



要么新建一个程序的实例并调用 Bar 就此而言;

Main is static but is calling Bar that is not. That won't work.

Either new up an instance of Program and call Bar on that;

static void Main()
{
  var p = new Program();
  p.Bar();
}

或者使 Bar static 。



希望这会有所帮助，

Or make Bar static.

Hope this helps,

你必须实例化CANBusRedDetails，CANBusYellowDetails，CANBusGreenDetails和CANBusOrangeDetails在你使用它们之前。

You must instantiate CANBusRedDetails, CANBusYellowDetails, CANBusGreenDetails and CANBusOrangeDetails before you use them.

CANBusRedDetails = new CANBusDetails; 
CANBusYellowDetails = new CANBusDetails; 
CANBusGreenDetails = new CANBusDetails; 
CANBusOrangeDetails = new CANBusDetails;
