匹配“"运算符是“ [英] Matching '' operator is required for '

问题描述

我正在使用以下代码段重载<运算符

I am using the following code snippets for overloading < operator

Class example
{

static bool operator < (example a ,example b)
{
 /* code goes here*/
}
}

当我尝试编译它时，我收到一条错误消息，说
运算符<需要匹配的运算符>也要定义.

如何克服此错误

when i try to compile it,I get a error saying that
the operator < requires a matching operator > also to be defined.

How to over come this error

推荐答案

这意味着，如果声明小于"运算符，则还必须声明大于"运算符.至少添加此内容:

What it means is that if you declare a "less than" operator, you must also declare a "greater than" operator. Add this at a minimum:

static bool operator > (example a ,example b)
{
 return !(b < a);
}
