问题描述
有没有人有一个非常简单的示例,说明如何在C#中重载复合赋值运算符?
Does anyone have a very simple example of how to overload the compound assignment operator in C#?
推荐答案
您不能显式重载复合赋值运算符.但是,您可以重载main运算符,编译器会对其进行扩展.
You can't explicitly overload the compound assignment operators. You can however overload the main operator and the compiler expands it.
x += 1
纯粹是x = x + 1
的语法糖,后者将被翻译为.如果重载+
运算符,它将被调用.
x += 1
is purely syntactic sugar for x = x + 1
and the latter is what it will be translated to. If you overload the +
operator it will be called.
public static Complex operator +(Complex c1, Complex c2)
{
return new Complex(c1.real + c2.real, c1.imaginary + c2.imaginary);
}
