在C#中重载复合赋值运算符的简单方法? [英] Simple way to overload compound assignment operator in C#?

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);
}
