无法写入注册表项

Question

当我试图在注册表中保存我的密钥时,我收到错误无法写入注册表项.

//这是我的代码

注意:我尝试以管理员身份运行,假设某些权限问题仍然出现同样的错误....

private const string RegistryKeyName = "Skms";
private readonly RegistryKey SoftwareKey = Registry.LocalMachine.OpenSubKey("SOFTWARE");

public KeyManagementRegistryKeyChangeImpl(bool writeable)
    {
        this.writable = writeable;
        RegistryKey skms; 
        if (Environment.Is64BitOperatingSystem == true) 
        {
            skms = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, RegistryView.Registry64).OpenSubKey(RegistryKeyName,true);

        }
        else
        {
            skms = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, RegistryView.Registry32);
        }

        if (null == skms)
        {
            skms = SoftwareKey.CreateSubKey(RegistryKeyName, RegistryKeyPermissionCheck.ReadWriteSubTree);
        }

        if(skms == null)
        {
            throw new System.ArgumentException(string.Format(CultureInfo.InvariantCulture, 
                @"Registry Key 'HKEY_LOCAL_MACHINE\SOFTWARE\{0}' not found or created",
                RegistryKeyName));
        }

        Decryptor decryptor = Decryptor.Create();

Answer 1

试试这个:

RegistryKey skms = SoftwareKey.OpenSubKey(RegistryKeyName, true);

如果您需要对密钥的写访问权,则应将第二个参数设置为true.

在64位系统上,您可以尝试此操作(如果您使用的是.Net 4):

private readonly RegistryKey SoftwareKey = 
    RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64).
    OpenSubKey("SOFTWARE");

Answer 2

if (null == skms)            
{             
   skms = Registry.LocalMachine.OpenSubKey("SOFTWARE",true);              
   RegistryKey key = skms.CreateSubKey(
          RegistryKeyName, RegistryKeyPermissionCheck.ReadWriteSubTree);      
}

这是我的问题的答案.

Answer 3

您可能会违反注册表重定向.也许你在64位系统上有一个32位进程,写入HKLM\Software会被重定向到HKLM\Software\Wow6432Node.

您需要直接打开64位密钥,或者为AnyCPU编译.
