我有一种感觉，我做错了。我是抽象类等的新手，并且已经阅读了一些教程，但我不知道如何将它应用于我的情况。我认为我的设计可能有问题，但我想不出另一种方法来做到这一点。我的公司生产了几台不同的计算机，我需要能够监控电池信息。虽然获取信息不是问题，但要弄清楚如何将不同的命令发送到基类来完成我需要它做的事情。假设我想获得我的电池 1 电压。在一个单元上，命令是 0x0418，在另一个单元上是 0x453。因此，在我的信息类中，我进行了测试以查看模型是什么。我有一个名为电池的基类，它有一堆标准的每个电池的变量（电池电压、充电 ic、

现在我对类的设计我认为是正确的（可能是错误的，因为我不擅长抽象和多态）。我有一个面板，最后会显示我从 BatteryInformation 类获得的信息。像 Battery1Cell1Label.Text = batteryInfo.GetCell1(1); Battery2Cell1Label = batteryInfo.GetCell1(2)。

所以在我的基类中，我想我需要一个 GetValue(byte command) （因为它是一个嵌入式控制器命令来获取每种不同类型的信息。）也许我应该停止说话，只是发布我所拥有的代码并告诉你我的错误。

电池.cs

public abstract class Battery<T> //not sure that the <T> is right
{
    public string Information { get; private set; }
    public float Cell1 { get; private set; }
    public float Cell2 { get; private set; }
    public float Cell3 { get; private set; }
    public float Cell4 { get; private set; }
    public int FCC { get; private set; }
    public bool ChargeIC { get; private set; }
    public int StartCharge { get; private set; }
    public int CurrentCharge { get; private set; }
    public bool Exists { get; private set; }

    protected internal void GetValue(byte command)
    {
        //Use Embedded controller to get said value
        //ECPort.ReadEC(command);
        //Testing Purposeses
        Console.WriteLine(command);
    }
}

电池8800.cs

class Battery8800 : Battery<Battery8800>
{
    public Battery8800() : base()
    {

    }
    public void GetValue(BatteryCommands command)
    {
        base.GetValue((byte)command);
    }

    public enum BatteryCommands
    {
        Battery1VoltageHigh = 0x0402,
        Battery1VoltageLow = 0x0403,
        Batt1ChargeCurrentHigh = 0x0404,
        Batt1ChargeCurrentLow = 0x0405,
        Battery1MaxError = 0x0407,
        Battery1RSOC = 0x0409,
        Battery1FCCHigh = 0x040E,
        Battery1FCCLow = 0x040F,
        Battery1DCHigh = 0x0412,
        Battery1DCLow = 0x0413,
        Battery1Cell1High = 0x0418,
        Battery1Cell1Low = 0x0419,
        Battery1Cell2High = 0x041A,
        Battery1Cell2Low = 0x041B,
        Battery1Cell3High = 0x041C,
        Battery1Cell3Low = 0x041D,
        Battery1Cell4High = 0x041E,
        Battery1Cell4Low = 0x041F,
        PowerSource1 = 0x0420,
//many more commands for battery 2 etc etc
    }
}

电池信息.cs

class BatteryInformation
{
    public Battery battery1; //error says it needs 1 type of argument
    public Battery battery2; //error says it needs 1 type of argument
    public BatteryInformation()
    {

        switch (UnitModel.GetModelEnum())
        {
            case UnitModel.DLIModel.DLI8300M:
                battery1 = new Battery8300();
                battery2 = new Battery8300();
                break;
            case UnitModel.DLIModel.DLI8400:
                battery1 = new Battery8400();
                battery2 = new Battery8400();
                break;
            case UnitModel.DLIModel.DLI8500:
                battery1 = new Battery8500();
                break;
            case UnitModel.DLIModel.DLI8500P:
                battery1 = new Battery8500P();
                break;
            case UnitModel.DLIModel.DLI8800:
                battery1 = new Battery8800();
                break;
            case UnitModel.DLIModel.DLI9200:
                battery1 = new Battery9200();
                break;
            default:
                break;
        }
        //for testing purposes
        battery1 = new Battery8800();
        battery1.DoThis(Battery8800.BatteryCommands.Batt1ChargeCurrentHigh);
    }
}

是的草稿保存！刚停电，我没有松口，而是一句话！

所以当我的电脑重新打开时，我想在我的电池面板课上做这样的事情可能会更好。

    //in my timer_tick event
    BatteryInformation.UpdateBatteries();
    battery1Cell1Label.Text = BatteryInformation.Battery1.Cell1.ToString();
    //etc etc

但我仍然需要让这个工作，但我很难弄清楚如何进行抽象。感谢您的时间。

我想我会以错误的方式解决这个问题。

class Battery1_8400 : Battery
{
    public override bool Update()
    {
        //TODO finish
        Exists = GetValue((ushort)Commands.PowerSource) != 0xFF;
        if (Exists)
        {
            Cell1 = GetValue((ushort)Commands.Cell1Low, (ushort)Commands.Cell1High) / 1000.0f;
            Cell2 = GetValue((ushort)Commands.Cell2Low, (ushort)Commands.Cell2High) / 1000.0f;
            Cell3 = GetValue((ushort)Commands.Cell3Low, (ushort)Commands.Cell3High) / 1000.0f;
            FCC = GetValue((ushort)Commands.FCCLow, (ushort)Commands.FCCHigh);
            Voltage = GetValue((ushort)Commands.VoltageLow, (ushort)Commands.VoltageHigh);
            return true;
        }
        else
        {
            return false;
        }
    }
    private enum Commands
    {
        PowerSource = 0x0480,
        Charge = 0x0432,
        RSOC = 0x0734,
        DCLow = 0x0402,
        DCHigh = 0x0403,
        FCCLow = 0x0404,
        FCCHigh = 0x0405,
        MaxError = 0x0730,
        Cell1Low = 0x0778,
        Cell1High = 0x0779,
        Cell2Low = 0x077C,
        Cell2High = 0x077D,
        Cell3Low = 0x0780,
        Cell3High = 0x0781,
        VoltageLow = 0x0438,
        VoltageHigh = 0x0439,
        ChargeCurrentLow = 0x0728,
        ChargeCurrentHigh = 0x0729,
        ChargeIC = 0x1A03,
    }
}

我有 9 个文件，就更新命令的工作方式而言，它们都是相同的，区别在于枚举。每个类的命令略有不同。查看batter2_8400.cs 的枚举

    private enum Commands
    {
        PowerSource = 0x0480,
        Charge = 0x04C2,
        RSOC = 0x0834,
        DCLow = 0x0492,
        DCHigh = 0x0493,
        FCCLow = 0x0494,
        FCCHigh = 0x0495,
        MaxError = 0x0830,
        Cell1Low = 0x0878,
        Cell1High = 0x0879,
        Cell2Low = 0x087C,
        Cell2High = 0x087D,
        Cell3Low = 0x0880,
        Cell3High = 0x0881,
        VoltageLow = 0x04C8,
        VoltageHigh = 0x04C9,
        ChargeCurrentLow = 0x0828,
        ChargeCurrentHigh = 0x0829,
        ChargeIC = 0x1A04,
    }

该更新命令与其他 7 个文件相同。对我来说似乎有点糟糕的设计，但我不知道该怎么做。顺便说一句，这就是我得到一个答案和收到的几条评论之后我的课程的样子。

您的基类 BatteryInformation 应该具有您需要检索的每个值的抽象属性，如下所示：

public abstract class BatteryInfo {
    // int should be replaced with the actual data type of the value
    public abstract int VoltageHigh { get; }
    public abstract int VoltageLow { get; }
    // etc. for each value you need
}

然后在您的子类中实现每个属性

public class Battery8800 : BatteryInfo {
    public override int VoltageHigh {
        get {
          int value;
          // do code to retrieve value
          return value;
        }
    }
}

另外，我会在某个地方提供一个你的 UI 可以使用的方法，如下所示：

 public IEnumerable<BatteryInfo> GetAllBatteryInfo() {
   // get each battery
 }

这样，用户界面就无需担心如何检索每个电池的电池信息。这允许您使用列表或网格样式控件之一来查看电池信息。

最后我想我知道我应该做什么了。它对我来说看起来很干净，似乎很有意义。也许你可以批评它？

public abstract class Battery
{
    public string Information { get; set; }
    public float Cell1 { get {return GetValue(Cell1Low, Cell1High) / 1000.0f;} }
    public float Cell2 { get {return GetValue(Cell2Low, Cell2High) / 1000.0f;} }
    public float Cell3 { get {return GetValue(Cell3Low, Cell3High) / 1000.0f;} }
    public float Cell4 { get {return GetValue(Cell4Low, Cell4High) / 1000.0f;} }
    public float Voltage { get {return GetValue(VoltageLow, VoltageHigh);} }
    public int DC { get {return GetValue(DCLow, DCHigh);} }
    public int FCC { get {return GetValue(FCCLow, FCCHigh);} }
    //public bool ChargeIC { get {return } }
    //public int StartCharge { get {return } }
    //public int CurrentCharge { get {return } }
    public bool Exists { get {return GetValue(PowerSource) != 0xFF} }
    public int FCCPercent { get {return ((FCC * 100) / DC);} }

    /// <summary>
    /// Gets a value depending on the Embedded controller
    /// </summary>
    /// <param name="low">The low byte command to process</param>
    /// <param name="high">The high byte command to process</param>
    /// <returns></returns>
    private int GetValue(ushort low, ushort high)
    {
        //Use Embedded controller to get said value
        //ECPort.ReadEC(command);
        //Testing Purposeses
        var lowValue = ECPort.ReadEC(low);
        var highValue = ECPort.ReadEC(high);
        return (int)((highValue << 8) + lowValue);
    }

    private int GetValue(ushort command)
    {
        return (int)ECPort.ReadEC(command);
    }

    public abstract ushort PowerSource {get;}
    public abstract ushort Charge{get;}
    public abstract ushort RSOC{get;}
    public abstract ushort DCLow{get;}
    public abstract ushort DCHigh{get;}
    public abstract ushort FCCLow{get;}
    public abstract ushort FCCHigh{get;}
    public abstract ushort MaxError{get;}
    public abstract ushort Cell1Low{get;}
    public abstract ushort Cell1High{get;}
    public abstract ushort Cell2Low{get;}
    public abstract ushort Cell2High{get;}
    public abstract ushort Cell3Low{get;}
    public abstract ushort Cell3High{get;}
    public abstract ushort Cell4Low { get; }
    public abstract ushort Cell4High { get; }
    public abstract ushort VoltageLow{get;}
    public abstract ushort VoltageHigh{get;}
    public abstract ushort ChargeCurrentLow{get;}
    public abstract ushort ChargeCurrentHigh{get;}
    public abstract ushort ChargeIC{get;}

}

然后在我继承它的子类上，一个例子就是这个

class Battery1_8400 : Battery
{
    public override ushort PowerSource { get {return 0x0480;}}
    public override ushort Charge { get {return  0x0432;}}
    public override ushort RSOC { get {return  0x0734;}}
    public override ushort DCLow { get {return  0x0402;}}
    public override ushort DCHigh { get {return  0x0403;}}
    public override ushort FCCLow { get {return  0x0404;}}
    public override ushort FCCHigh { get {return  0x0405;}}
    public override ushort MaxError { get {return  0x0730;}}
    public override ushort Cell1Low { get {return  0x0778;}}
    public override ushort Cell1High { get {return  0x0779;}}
    public override ushort Cell2Low { get {return  0x077C;}}
    public override ushort Cell2High { get {return  0x077D;}}
    public override ushort Cell3Low { get {return  0x0780;}}
    public override ushort Cell3High { get {return  0x0781;}}
    public override ushort VoltageLow { get {return  0x0438;}}
    public override ushort VoltageHigh { get {return  0x0439;}}
    public override ushort ChargeCurrentLow { get {return  0x0728;}}
    public override ushort ChargeCurrentHigh { get {return  0x0729;}}
    public override ushort ChargeIC { get {return  0x1A03;}}
}

现在我所要做的就是编辑一个文件battery.cs，如果我需要对其进行更改。
