如何在 C# 中导入 ZwDeleteKey："External component has thrown an exception"

Question

我正在尝试使用 ZwDeleteKey 删除注册表符号 link。
我是这样导入的：

[DllImport("NtosKrnl.exe", CharSet = CharSet.Ansi, EntryPoint = "ZwDeleteKey", SetLastError = true)]  
private static extern int ZwDeleteKey(SafeRegistryHandle hKey);

但是在我调用它之后，我收到一个异常：

"External component has thrown an exception"

我的完整代码：

[DllImport("NtosKrnl.exe", CharSet = CharSet.Ansi, EntryPoint = "ZwDeleteKey", SetLastError = true)]  
private static extern int ZwDeleteKey(SafeRegistryHandle hKey);  

public static RegistryKey OpenSubKeySymLink(this RegistryKey key, string name, RegistryRights rights = RegistryRights.ReadKey, RegistryView view = 0)
{
    var error = RegOpenKeyExW(key.Handle, name, REG_OPTION_OPEN_LINK, ((int)rights) | ((int)view), out var subKey);
    if (error != 0)
    {
        subKey.Dispose();
        throw new Win32Exception(error);
    }
    return RegistryKey.FromHandle(subKey);
}  


static void Main(string[] args)
{
    RegistryKey key;
    key = OpenSubKeySymLink(Microsoft.Win32.Registry.CurrentUser, @"SOFTWARE\Microsoft\Windows\ABC", RegistryRights.ReadKey, 0);
    ZwDeleteKey(key.Handle);
}

ZwDeleteKey 的官方文档确实提到“NtosKrnl.exe”是“DLL”，但这是错误的，导入定义应该是这样的（而且没有涉及字符串，条目点没有歧义并且函数没有设置最后一个错误):

[DllImport("ntdll")]
private static extern int ZwDeleteKey(SafeRegistryHandle hKey);
