Question

嗨，有人可以给我一些帮助，这是我的Enum代码

    Enum _WSC_SECURITY_PROVIDER
    WSC_SECURITY_PROVIDER_FIREWALL = &H1
    WSC_SECURITY_PROVIDER_AUTOUPDATE_SETTINGS = &H2
    WSC_SECURITY_PROVIDER_ANTIVIRUS = &H4
    WSC_SECURITY_PROVIDER_ANTISPYWARE = &H8
    WSC_SECURITY_PROVIDER_INTERNET_SETTINGS = &H16
    WSC_SECURITY_PROVIDER_USER_ACCOUNT_CONTROL = &H32
    WSC_SECURITY_PROVIDER_SERVICE = &H64
    WSC_SECURITY_PROVIDER_NONE = &H0
End Enum
    Enum _WSC_SCANNER_SETTINGS
    SCANNER_UNKNOWN = &H1
    SCANNER_RUNNING = &H16
End Enum
Enum _WSC_UPTODATE
    up_To_Date = &H0
    too_Old = &H10
End Enum

所以我得到这个十六进制值：61100在二进制中是：1100001000100000000，我希望我的输出是

WSC_SECURITY_PROVIDER_ANTIVIRUS + WSC_SECURITY_PROVIDER_AUTOUPDATE_SETTINGS + ???? + up_To_Date

到现在为止，我只有这个，但它没有做我想做的事情

        Dim _security As _WSC_SECURITY_PROVIDER = hex.Substring(0, 2)
        Dim _scanner As _WSC_SCANNER_SETTINGS = hex.Substring(2, 2)
        Dim _uptodate As _WSC_UPTODATE = hex.Substring(4, 2)

        Console.WriteLine("_security={0}, _scanner={1}, _uptodate={2}",
                          _security,
                          _scanner,
                          _uptodate
                          )

我会很感激提示。

如果您正在设计一个用于表示标志，单个位的枚举，则枚举中的项应为2的幂，十六进制16为三位。我创建这个枚举作为模板，所以我不需要做很多打字。只需更改名称即可。

<FlagsAttribute()> _
Public Enum bit As Integer
    none = 0
    s0 = 1 << 0
    s1 = 1 << 1
    s2 = 1 << 2
    s3 = 1 << 3
    s4 = 1 << 4
    s5 = 1 << 5
    s6 = 1 << 6
    s7 = 1 << 7
    s8 = 1 << 8
    s9 = 1 << 9
    s10 = 1 << 10
    s11 = 1 << 11
    s12 = 1 << 12
    s13 = 1 << 13
    s14 = 1 << 14
    s15 = 1 << 15
    s16 = 1 << 16
    s17 = 1 << 17
    s18 = 1 << 18
    s19 = 1 << 19
    s20 = 1 << 20
    s21 = 1 << 21
    s22 = 1 << 22
    s23 = 1 << 23
    s24 = 1 << 24
    s25 = 1 << 25
    s26 = 1 << 26
    s27 = 1 << 27
    s28 = 1 << 28
    s29 = 1 << 29
    s30 = 1 << 30
    all = -1
End Enum

通常我会注释掉未使用过的物品，但留下它们。
