现在我的班级设置为:
enum Unit{Inches,Centimeters};
稍后我有一个步骤,将每个单元的所有属性设置为我的类实例变量。例如:
int unitBase; //10 for metric, 16 for american
int label;
switch(unit)
{
case Unit.Inches: unitBase = 16; unitLabel = "\"";break;
case Unit.Centimeters: unitBase = 10; unitLabel = "cm";break;
}
我宁愿将这些全部存储在Unit类或结构中。然后,我希望能够以与访问颜色相同的方式访问它,例如。你说Color.Blue
为蓝色,我想说Unit.Inches
表示英寸......这就是为什么我不制作一个单位基类而只是扩展它。
我知道有办法做到这一点!谁能开导我?
谢谢!

您可以使用静态属性:
public enum UnitSpecifier{Inches,Centimeters};
public class Unit
{
int unitBase; //10 for metric, 16 for american
string unitLabel;
public Unit(UnitSpecifier unit)
{
switch (unit)
{
case UnitSpecifier.Inches: unitBase = 16; unitLabel = @"\"; break;
case UnitSpecifier.Centimeters: unitBase = 10; unitLabel = "cm"; break;
}
}
public static readonly Unit Inches = new Unit(UnitSpecifier.Inches);
}

public struct Unit {
public static readonly Unit Inches = new Unit(16, "\"");
public static readonly Unit Centimeters = new Unit(10, "cm");
private readonly int _unitBase;
private readonly string _unitLabel;
static Unit() { }
private Unit(int unitBase, string unitLabel) {
this._unitBase = unitBase;
this._unitLabel = unitLabel;
}
public int UnitBase {
get { return this._unitBase; }
}
public string UnitLabel {
get { return this._unitLabel; }
}
}
