如何使用硬编码值声明自定义数据类型的静态数组？

Question

目标:

我想为不经常更改的数据实现硬编码查找表,但是当它确实发生更改时,我希望能够快速更新程序并重建.

计划:

我的计划是定义一个自定义数据类型...

private class ScalingData
{
    public float mAmount;
    public String mPurpose;
    public int mPriority;

    ScalingData(float fAmount, String strPurpose, int iPriority)
    {
        mAmount = fAmount;
        mPurpose = strPurpose;
        mPriority = iPriority;
    }
}

然后,在主类中,像这样对数组进行硬编码......

public static ScalingData[] ScalingDataArray =
{
        {1.01f, "Data point 1", 1},
        {1.55f, "Data point 2", 2}
};

但是,这不构建.我一直看到消息" Type mismatch: cannot convert from float[] to ScalingData".

我怎样才能实现目标？

UPDATE

到目前为止,我已尝试实施这些建议,但仍然遇到错误......

代码如下:

public class CustomConverter
{
    //Lookup Table
    private static ScalingData[] ScalingDataArray =
    {
        new ScalingData(1.01f, "Data point 1", 1),
        new ScalingData(1.55f, "Data point 2", 2)
    };


    //Constructor
    CustomConverter()
    {
        //does stuff
    }


    //Custom Data type
    private class ScalingData
    {
        public float mAmount;
        public String mPurpose;
        public int mPriority;

        ScalingData(float fAmount, String strPurpose, int iPriority)
        {
            mAmount = fAmount;
            mPurpose = strPurpose;
            mPriority = iPriority;
        }
    }
}

并且硬编码数组的错误是

No enclosing instance of type CustomConverter is accessible.
   Must qualify the allocation with an enclosing instance of type CustomConverter
   (e.g. x.new A() where x is an instance of CustomConverter).

编辑...完整的解决方案,如下面的答案

public class CustomConverter
{
    //Lookup Table
    private static ScalingData[] ScalingDataArray =
    {
        new ScalingData(1.01f, "Data point 1", 1),
        new ScalingData(1.55f, "Data point 2", 2)
    };


    //Constructor
    CustomConverter()
    {
        //does stuff
    }


    //Custom Data type
    private static class ScalingData
    {
        public float mAmount;
        public String mPurpose;
        public int mPriority;

        ScalingData(float fAmount, String strPurpose, int iPriority)
        {
            mAmount = fAmount;
            mPurpose = strPurpose;
            mPriority = iPriority;
        }
    }
}

你不能用Java做到这一点.你需要像这样使用构造函数:

public static ScalingData[] ScalingDataArray =
{
        new ScalingData(1.01f, "Data point 1", 1),
        new ScalingData(1.55f, "Data point 2", 2)
};
