问题描述

嗨


我有一个OrderedDictionary对象，其中键是枚举。是否有一个

简单的方法将它转换为整数？示例/文件赞赏。


谢谢

Andrew

Hi

I have an OrderedDictionary object where the key is an enum. Is there an
easy way to cast it to an integer? Examples/document appreciated.

Thanks
Andrew

推荐答案

Andrew，


如果键作为对象返回给你，那么你必须首先将它转换为枚举类型，然后是int，如下所示：


对象键= ...;

int keyInt =（int）（EnumType）键;


希望这会有所帮助。

Andrew,

If the key is returned to you as an object, then you have to cast it to
the enum type first, then an int, like so:

object key = ...;
int keyInt = (int) (EnumType) key;

Hope this helps.

只是好奇，你怎么不能直接去一个int？


谢谢。

Saad，


因为当您取消装箱值类型时，您必须先取消装入正确的

类型。它不是一个强制转换操作（虽然语法相同）。

Saad,

Because when you unbox a value type, you have to unbox to the correct
type first. It''s not a casting operation (although the syntax is the same).
