我试图弄清楚枚举是如何工作的,我试图制作一个函数来写入注册表,使用枚举作为注册表根,但有点混淆
public enum RegistryLocation
{
ClassesRoot = Registry.ClassesRoot,
CurrentUser = Registry.CurrentUser,
LocalMachine = Registry.LocalMachine,
Users = Registry.Users,
CurrentConfig = Registry.CurrentConfig
}
public void RegistryWrite(RegistryLocation location, string path, string keyname, string value)
{
// Here I want to do something like this, so it uses the value from the enum
RegistryKey key;
key = location.CreateSubKey(path);
// so that it basically sets Registry.CurrentConfig for example, or am i doing it wrong
..
}
问题是,您试图使用类初始化枚举值,并将枚举值用作类,但您无法做到这一点。来自MSDN:
枚举的批准类型有byte、sbyte、short、ushort、int、,uint、long或ulong。
您可以做的是将枚举作为标准枚举,然后让一个方法基于该枚举返回正确的RegistryKey。
例如:
public enum RegistryLocation
{
ClassesRoot,
CurrentUser,
LocalMachine,
Users,
CurrentConfig
}
public RegistryKey GetRegistryLocation(RegistryLocation location)
{
switch (location)
{
case RegistryLocation.ClassesRoot:
return Registry.ClassesRoot;
case RegistryLocation.CurrentUser:
return Registry.CurrentUser;
case RegistryLocation.LocalMachine:
return Registry.LocalMachine;
case RegistryLocation.Users:
return Registry.Users;
case RegistryLocation.CurrentConfig:
return Registry.CurrentConfig;
default:
return null;
}
}
public void RegistryWrite(RegistryLocation location, string path, string keyname, string value) {
RegistryKey key;
key = GetRegistryLocation(location).CreateSubKey(path);
}
