管理枚举到非托管enum metro应用程序 [英] Managed enum to unmanaged enum metro apps

问题描述

我有疑问。

我需要将托管枚举转换为非托管枚举。

Hi,

I have a doubt.
I need to convert managed enum to unmanaged enum.

enum class MANAGED
{
   TYPE1,
   TYPE2
}

enum UNMANAGED
{
   TYPE1,
   TYPE2
}

我做了填充码

I did the fillowing code

UNMANAGED unman = (UNMANAGED)((int)man);

但是我得到未定义的值变量 unman





请回复....

提前谢谢..

But i'm getting undefined value in the variable unman


Please reply....
Thanks in advance..

推荐答案

因为你使用的是MANAGED枚举，它不会自动转换为int所以你应该有：

Because your using MANAGED enum it will not be converted automatically to int so you should have:

int temp = (int)man; //But "man" must be initialized!  
UNMANAGED unman = (UNMANAGED)temp;

假设变量'man属于MANAGED类型并被分配，此代码将工作：

Assuming the variable 'man is of Type MANAGED, and is assigned, this code will work:

MANAGED man = MANAGED.TYPE1;
UNMANAGED un = (UNMANAGED)((int)man);

一个明显的错误是你在这里使用'class： enum class MANAGED 这个词。



这样可行：

An obvious bug is your use of the word 'class here: enum class MANAGED.

This will work:

MANAGED man = MANAGED.TYPE1;
UNMANAGED un = (UNMANAGED) man;

因为每个Enum值都有一个内在数值：不需要转换（到整数）。

Because each Enum value has an intrinsic numeric value: conversion (to integer) is not required.
