这些(+ =，-=，* =，/=)运算符是什么意思? [英] What do these ( += , -= , *= , /= ) Operators Mean?

问题描述

我一直到处寻找这些含义以及它们的用法+=，-=，*=，/=，我发现的最多就是它们，加法分配" ，按差异分配"，按产品分配"，按商分配"等，但我不知道何时或如何使用它们.如果有人可以向我解释这一点，我将不胜感激.谢谢

I have been looking everywhere to figure out what these mean and how they are used +=, -=, *=, /=, the most I have found is that they are, "Assignment by Addition", "Assignment by Difference", "Assignment by Product", "Assignment by Quotient", etc, but I can't figure out when or how they are used. If anyone can please explain this to me I would be very grateful. thanks

推荐答案

它们是简写形式:

a += b

与

a = a + b

等等...

如此

• a -= b等同于a = a - b
• a *= b等同于a = a * b
• a /= b等同于a = a / b

• a -= b is equivalent to a = a - b
• a *= b is equivalent to a = a * b
• a /= b is equivalent to a = a / b

如Kevin Brydon所建议-熟悉C#中的运算符

As Kevin Brydon suggested - Familiarize yourself with the operators in C# here.
