C ++字符串到枚举 [英] C++ string to enum

问题描述

在C ++中有一个简单的方法将字符串转换为枚举（类似于C＃中的 Enum.Parse ）？

Is there a simple way in C++ to convert a string to an enum (similar to Enum.Parse in C#)? A switch statement would be very long, so I was wondering if there is a simpler way to do this?

编辑：

感谢您的所有回复。我意识到有一个更简单的方法来做我的特定情况。字符串总是包含字符'S'后面跟一些数字，所以我只是

Thanks for all of your replies. I realized that there was a much simpler way to do it for my particular case. The strings always contained the charater 'S' followed by some number so i just did

int i = atoi(myStr.c_str() + 1);

然后在i上做了一个开关。

and then did a switch on i.

推荐答案

std :: map< std :: string，MyEnum> （或 unordered_map ）可以轻松做到。填充地图将像switch语句一样枯燥乏味。

A std::map<std::string, MyEnum> (or unordered_map) could do it easily. Populating the map would be just as tedious as the switch statement though.
