访问类属性，而不使用点运算符 [英] Accessing a Class property without using dot operator

问题描述

我需要使用Double类型调用时，重载一些运营商。要做到这一点，我创建一个类MyDouble，从双继承。 MyDouble看起来有点像这样

I need to overload some operators when called using Double types. To achieve this, I'm creating a class MyDouble, which inherits from Double. MyDouble looks somewhat like this

class MyDouble : Double
{
   Double value;
   // operator overloads go here
}

我要抽象掉了从用户值属性，以便它是可用的只是作为一个双。基本上，我希望用户能够做到这一点：

I want to abstract away the value property from the user so that it is usable just as a Double. Basically I want the user to be able to do this:

MyDouble a = 5;         //a.value gets assigned 5
Console.WriteLine(a);   //prints a.value

我不希望用户有专门针对值属性。这可能吗？ ？我将如何去了解它。

I don't want the user to have to specifically target the value property. Is this possible? How would I go about it?

推荐答案

您可以定义的隐式转换操作符，就像这样：

You can define an implicit conversion operator, like this:

class MyDouble {
    public Value {get; private set;}
    public Double(double value) {
        Value = value;
    }
    // Other declarations go here...
    public static implicit operator double(MyDouble md) {
        return md.Value;
    }
    public static implicit operator MyDouble(double d) {
        return new MyDouble(d);
    }
}
