            byte[] b = new byte[d.Count()];

            for (int i = 0; i < d.Count(); i++)
            {
                b[i] = Convert.ToByte("0x" + d[i], 16);
            }
            Registry.LocalMachine.OpenSubKey("SOFTWARE").OpenSubKey("Ultimus", true).SetValue("Init2", b, RegistryValueKind.Binary);
            Console.WriteLine("成功！");
            Thread.Sleep(1000);
        }
    }
}

把十六进制字符串转成二进制。

 try
  {
  ConnectionOptions mConn = new ConnectionOptions();
  mConn.Username = user;
  mConn.Password = pwd;
  ManagementClass mClass = new ManagementClass();
  mClass.Scope = new ManagementScope("\\\\" + strIP + "\\root\\default", mConn);
  mClass.Path = new ManagementPath("StdRegProv");
  ManagementBaseObject inParams = mClass.GetMethodParameters("GetStringValue");
  inParams["hDefKey"] = 0x80000002;//field
  inParams["sSubKeyName"] = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Installer";//path
  inParams["sValueName"] = "InstallerLocation";//key
  ManagementBaseObject outParams = mClass.InvokeMethod("GetStringValue", inParams, null);
  string value = outParams["sValue"].ToString();//value
  }
  catch ( )
  {
  } 



连接远程服务器修改其注册表。

cmd-》regedit打开注册表。
