如何通过它的号码访问枚举成员 [英] how to access to enumeration member via it's number
问题描述
您好，
我必须关注此问题。
基于枚举声明类型：
"
enum TpAddressPlan {
P_ADDRESS_PLAN_NOT_PRESENT = 0，
P_ADDRESS_PLAN_UNDEFINED = 1，
P_ADDRESS_PLAN_IP = 2，
P_ADDRESS_PLAN_MULTICAST = 3，
P_ADDRESS_PLAN_UNICAST = 4，
P_ADDRESS_PLAN_E164 = 5，
P_ADDRESS_PLAN_AESA = 6，
P_ADDRESS_PLAN_URL = 7，
P_ADDRESS_PLAN_NSAP = 8，
P_ADDRESS_PLAN_SMTP = 9，
P_ADDRESS_PLAN_MSMAIL = 10，
P_ADDRESS_PLAN_X400 = 11 ，
P_ADDRESS_PLAN_SIP = 12，
P_ADDRESS_PLAN_ANY = 13，
P_ADDRESS_PLAN_MIN = 14
};
typedef enum TpAddressPlan TpAddressPlan;
"
函数接收一个对应于枚举的整数
成员我必须转换为成员来填充结构成员
类型TpAddressPlan：
"
this-> msg.CEType_u.msgreq.CERequest_u.qryreq.userID.Pla n =
AddressPlan; // [0-14]
"
我如何为AddressPlan分配枚举值，从
开始'的整数值：种类
??? AddressPlan = TpAddressPlan（i）???
感谢您的帮助！
Hello,
I have to following issue.
A type is declared based on an enum:
"
enum TpAddressPlan {
P_ADDRESS_PLAN_NOT_PRESENT = 0,
P_ADDRESS_PLAN_UNDEFINED = 1,
P_ADDRESS_PLAN_IP = 2,
P_ADDRESS_PLAN_MULTICAST = 3,
P_ADDRESS_PLAN_UNICAST = 4,
P_ADDRESS_PLAN_E164 = 5,
P_ADDRESS_PLAN_AESA = 6,
P_ADDRESS_PLAN_URL = 7,
P_ADDRESS_PLAN_NSAP = 8,
P_ADDRESS_PLAN_SMTP = 9,
P_ADDRESS_PLAN_MSMAIL = 10,
P_ADDRESS_PLAN_X400 = 11,
P_ADDRESS_PLAN_SIP = 12,
P_ADDRESS_PLAN_ANY = 13,
P_ADDRESS_PLAN_MIN = 14
};
typedef enum TpAddressPlan TpAddressPlan;
"
And a function receive an integer corresponding to the enumeration
member that I must convert into the member to fill a structure member
of the type TpAddressPlan:
"
this->msg.CEType_u.msgreq.CERequest_u.qryreq.userID.Pla n =
AddressPlan; // [0-14]
"
How can I assign to AddressPlan the enumeration value, starting from
it''s integer value: kind of
???AddressPlan = TpAddressPlan (i)???
Thanks for your help!

你不需要C ++中的typedef。
You don''t need a typedef in C++.
和一个函数接收一个对应于枚举
成员的整数，我必须将其转换为成员以填充结构成员
类型为TpAddressPlan：
" ;
this-> msg.CEType_u.msgreq.CERequest_u.qryreq.userID.Pla n =
AddressPlan; // [0-14]
"

AddressPlan; // [0-14]
"
How can I assign to AddressPlan the enumeration value, starting from

如果你确定我在正确的范围内（0-14）并且值
对应于正确的枚举那么只是使用
AddressPlan = TpAddressPlan（i）;

If you are sure that i is in the correct range (0-14) and the value
corresponds to the right enumeration then just use
AddressPlan = TpAddressPlan(i);

这是不必要的。变量声明中的'enum'是可选的。
That''s unnecessary. ''enum'' in variable declarations is optional.

这就是你的确切方式。

非常感谢!!!所有。
我写了AddressPlan = TpAddressPlan [i]!!这就是问题！
无论如何，我并不知道AddressPlan = TpAddressPlan（i）将
工作。
非常感谢！
Thanks a lot!!! all.
I wrote "AddressPlan = TpAddressPlan[i]"!! That was the issue!
Anyway, I didn''t knew that "AddressPlan = TpAddressPlan(i)" would
work.
Thanks a lot!
