Question

我编写了一个程序，该程序可以获取Windows产品密钥以通过Windows注册表检查激活。我使用Open Base Key来获得适合于字符串和二进制值的本地计算机。但是，当我使用Open Remote Base Key从远程计算机获取产品ID时，它仅返回字符串值，而对于二进制值则返回null。

首先：在当前PC上测试时可以。我将代码更改为远程。它返回空值（请参见下面的代码）下一步：使用代码，我得到一个字符串值。这是工作。但是对于二进制文件，它返回null

try
{    
    //This get reg info from current PC
    //RegistryKey key = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64);
    //This get reg info from remote PC
    RegistryKey key = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, Environment.MachineName);
    string keyPath = @"Software\Microsoft\Windows NT\CurrentVersion";
    byte[] rpk = (byte[])key.OpenSubKey(keyPath).GetValue("DigitalProductId");
    Console.WriteLine(key.OpenSubKey(keyPath).GetValue("InstallDate"));
    Console.WriteLine(key.OpenSubKey(keyPath).GetValue("InstallDate"));
    string serial = "";
    const string possible = "BCDFGHJKMPQRTVWXY2346789";
    for (int i = 0; i < 25; i++)
    {
        int accu = 0;
        for (int a = 0; a < 15; a++)
        {
             accu <<= 8;
             accu += rpk[66 - a];
             rpk[66 - a] = (byte)(accu / 24 & 0xff);
             accu %= 24;
        }
        serial = possible[accu] + serial;
        if (i % 5 == 4 && i < 24)
        {
            serial = "-" + serial;
        }
    }
    return serial;
}
catch(Exception ex)
{
    Console.WriteLine(ex);
    return "No Found";
}

对象引用未设置为对象的实例

我无法从远程获取二进制值
