为什么迭代枚举返回重复键?(Why Iterating through the enum return duplicate keys?)

我现在正在处理有关注册表的一些事情。

我检查了System.Security.AccessControl的枚举RegistryRights

public enum RegistryRights
{
    QueryValues = 1,
    SetValue = 2,
    CreateSubKey = 4,
    EnumerateSubKeys = 8,
    Notify = 16,
    CreateLink = 32,
    Delete = 65536,
    ReadPermissions = 131072,
    WriteKey = 131078,
    ExecuteKey = 131097,
    ReadKey = 131097,
    ChangePermissions = 262144,
    TakeOwnership = 524288,
    FullControl = 983103,
}

这个枚举是一个按位,我知道枚举可以包含重复的值。 我试图通过这段代码迭代枚举:

 foreach (System.Security.AccessControl.RegistryRights regItem in Enum.GetValues(typeof(System.Security.AccessControl.RegistryRights)))
        {
            System.Diagnostics.Debug.WriteLine(regItem.ToString() + "  " + ((int)regItem).ToString());
        }

还有Enum.GetName(typeof(RegistryRights),regItem)返回相同的键名。

我得到的输出是:


QueryValues  1
SetValue  2
CreateSubKey  4
EnumerateSubKeys  8
Notify  16
CreateLink  32
Delete  65536
ReadPermissions  131072
WriteKey  131078
ReadKey 131097 ReadKey 131097
ChangePermissions  262144
TakeOwnership  524288
FullControl  983103

有人可以告诉我为什么我会得到重复的键?(“ReadKey”而不是“ExecuteKey”) 如何强制它将int转换为值的第二个键? 为什么ToString不返回真正的键值?


I am working now on some stuff regarding registry.

I checked the enum RegistryRights in System.Security.AccessControl.

public enum RegistryRights
{
    QueryValues = 1,
    SetValue = 2,
    CreateSubKey = 4,
    EnumerateSubKeys = 8,
    Notify = 16,
    CreateLink = 32,
    Delete = 65536,
    ReadPermissions = 131072,
    WriteKey = 131078,
    ExecuteKey = 131097,
    ReadKey = 131097,
    ChangePermissions = 262144,
    TakeOwnership = 524288,
    FullControl = 983103,
}

This enum is a bitwise,And I know that enums can contains duplicate values. I was trying to iterate through the enum by this code:

 foreach (System.Security.AccessControl.RegistryRights regItem in Enum.GetValues(typeof(System.Security.AccessControl.RegistryRights)))
        {
            System.Diagnostics.Debug.WriteLine(regItem.ToString() + "  " + ((int)regItem).ToString());
        }

also Enum.GetName(typeof(RegistryRights),regItem) return the same key name.

and the output I got is:


QueryValues  1
SetValue  2
CreateSubKey  4
EnumerateSubKeys  8
Notify  16
CreateLink  32
Delete  65536
ReadPermissions  131072
WriteKey  131078
ReadKey  131097
ReadKey  131097
ChangePermissions  262144
TakeOwnership  524288
FullControl  983103

Can someone please tell me why do I get duplicate keys?("ReadKey" instead of "ExecuteKey") How can I force it to cast the int to the second key of the value ? and why ToString does not return the real key value?

最满意答案

检查以下代码:

            var appXml:XML = NativeApplication.nativeApplication.applicationDescriptor;
            var ns:Namespace = appXml.namespace(); 
            trace(appXml.ns::version); 

Check the following code:

            var appXml:XML = NativeApplication.nativeApplication.applicationDescriptor;
            var ns:Namespace = appXml.namespace(); 
            trace(appXml.ns::version);
