重载赋值运算符 [英] Overloading the assignment operator

问题描述

我读过，基本上在C#中，赋值运算符不会发生.这确实在加剧.我从一个FormCollection中获取值，当我获取它们时，这些值都是字符串.我正在编写如下代码:

I've read that basically in C# overloading the assignment operator isn't going to happen. This is truly aggravating. I'm picking up values from a FormCollection, which are all strings as I get them. I was writing loads of code like:

 

bool isTrue = Convert.ToBool(formCollection["someBoolean"]);

推荐答案

您需要研究隐式和显式运算符.  (对于您给出的示例，显式运算符可能是最好的)，它们应该让您完全按照自己的意愿进行操作，即让编译器自动使用 尝试分配当前不匹配的类型时使用静态转换方法.

You'll want to look into the implicit and explicit operators.  (The explicit operator would probably be best for the examples you've given) They should let you do exactly what you want to do, namely have the compiler automatically use a static conversion method when you attempt to assign a type that doesn't currently match.
