C#通过rdp账密直接打开远程桌面

思路是首先新建一个vbs脚本，再创建一个bat脚本，再创建rdp文件，运行顺序是vbs->bat->rdp。rdp文件里面包含远程电脑的账密和其它信息，这样就可以不用再输入账密，而在程序里完成账密的设置，直接启动远程桌面（bat文件用vbs启动运行可以避免显示cmd的exe窗口），用C#语言写出这几个脚本，直接调用就可以实现功能（C#代码文尾），如下图

runBat.vbs文件里写

set ws=WScript.CreateObject("WScript.Shell")
ws.Run"runRdp.bat",

runRdp.bat文件里写

mstsc rdesktop.rdp /console /v: 192.168.0.167:

rdesktop.rdp里面写如下代码，注意username和password分别是远程电脑的登录账密

我们可以看到rdp文件里的密码很长，如下

01000000D08C9DDF0115D1118C7A00C04FC297EB01000000FBCFD336AC9B0D44B66EA56EE800C1E404000000020000000000106600000001000020000000EFDB7BB10E9F6509EEBF8C97E6BDC42BCB1E85AF5A801FC9623A21A4B628657B000000000E8000000002000020000000C0D7FAC8785CE745D7655BA1D97F2A16251EC23920D7B81DFE27BD29ED7A6D3910000000CAD751C2CEC0C749109F6C83AA90778F40000000751DB383D24B379C386A54EA93C50BA1B3AF96403D05BF252E7B10497C8BAE309AEF2F077C96EB241727A7D4023F7959DABFF48BC17615448681DAB3D1A3447A

密码是怎么来的呢，如下是加密算法，传入的参数pw是明文密码，比如上面的密码是123456，通过如下方法加密即可得到rdp里的密码

 /// <summary>
        /// 获取RDP密码
        /// </summary>
        private string  GetRdpPassWord(string pw)
        {
            byte[] secret = Encoding.Unicode.GetBytes(pw);
            byte[] encryptedSecret = Protect(secret);
            string res = string.Empty;
            foreach (byte b in encryptedSecret)
            {
                res += b.ToString("X2"); //转换16进制的一定要用2位
            }
            return res;
        }
 
        /// <summary>
        /// 加密方法
        /// </summary>
        /// <param name="data"></param>
        /// <returns></returns>
        private  static byte[] Protect(byte[] data)
        {
            try
            {
                //调用System.Security.dll
                return ProtectedData.Protect(data, s_aditionalEntropy, DataProtectionScope.LocalMachine);
            }
            catch (CryptographicException e)
            {
                Console.WriteLine("Data was not encrypted. An error occurred.");
                Console.WriteLine(e.ToString());
                return null;
            }
        }

基本思路就是这样，附上打开远程桌面的C#类

            string password = GetRdpPassWord(pw);
