C#域内远程机文件信息注册表访问。

  1. 获取远程机IP地址。

public string GetMachineIPAddress(string strMachineName)
        {
            string strMachineIP;
            Ping oP = new Ping();   // Declare a ping hander object.
            PingReply oPR = oP.Send(strMachineName);    // Get the return values from ping method.
            strMachineIP = oPR.Address.ToString();  // Get the target machine IP address.
            return strMachineIP;
        }

 2. 判断系统类型32/64.

public string GetMachineBit(string strMachineName)  // Return the remoting machine system bit number.
        {
            string strReturnStatus;
            string strAccessPath;
            string sTempMCIP;
            string[] aFiles;
            bool bISBIT;

            strReturnStatus = "32";
            try
            {
                
                sTempMCIP = GetMachineIPAddress(strMachineName); // Call local method to get the remote machine IP address.
                strAccessPath = @"\\"+ sTempMCIP + @"\\C$"; // Access the remote serveer driver C:.
 
                aFiles = Directory.GetDirectories(strAccessPath);  // Access to the target machine c$\Program Files folder.
                for (int i = 0; i < aFiles.Length - 1; i++) // Ergodic the folder info on remote driver C:
                { 
                    bISBIT = aFiles[i].ToString().Contains("Program Files (x86)");
                    if (bISBIT) // It is a 64 bit system if contain the X86 folder.
                    { 
                        strReturnStatus = "64"; // Return the judgement result.
                    }
                }
                 
                return strReturnStatus;
            }
            catch (Exception xe)
            { 
                strReturnStatus = xe.Message;
                return strReturnStatus;
            }
            
        }

 3.  从注册表获取某个文件的安装路径信息。

        public string GetRemoteMachinGenInstallPath(string sRemoteName)
        {
            
            remoteName = sRemoteName;  
            strRemoteMCGenInsPath = "No Geneva Install";
            
            try
            {
                if ((GetMachineBit(remoteName) == "32"))  //Call local method get the remote system bit info.
                {
                    // The sub key path for 32bit system.
                    strKeyPath = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
                }
                else
                {
                    if (GetRemoteOSVersion(remoteName).Contains("Microsoft Windows Server 2003")) // The WinServer2003 for 32 and 64 has the same key path, but other OS need access the WOW64 key node path.
                    {
                        strKeyPath = @"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
                    }
                    else
                    {
                        // The sub key path for 64bit system.
                        strKeyPath = @"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall";
                        //strKeyPath = @"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{6F13B97D-6FA6-49A3-90D6-653099B9E7A7}";
                    }
                }

                // Open the remote machine uninstall node subkey.
                environmentKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, remoteName).OpenSubKey(strKeyPath);


                if (environmentKey != null)
                {
                    lsRemoveSubKeys = environmentKey.GetSubKeyNames();  // Get the all the key name which under the uninstall node.
                    if (lsRemoveSubKeys.Length > 0)
                    {
                        foreach (string uninstallKey in lsRemoveSubKeys) // Ergodic the keys under uninstall and pick up the subkey which has the Gen app install path attribute value.
                        { 
                            RegistryKey rkUninstallKey = environmentKey.OpenSubKey(uninstallKey);   // Open subkey node in order to get the attribute text.

                            string installpath = (String)rkUninstallKey.GetValue("InstallLocation", String.Empty);  // Get the attribute value from InstallLocation node.
                            string strDisplayName = (String)rkUninstallKey.GetValue("DisplayName", String.Empty);   // Get the attribute value from DisplayName node.

                            //string uninstallString = (String)rkUninstallKey.GetValue("UninstallString", String.Empty);
                            if (strDisplayName.Contains("Geneva Application Server"))// && !uninstallString.Contains("InstallShield Installation Information"))
                            {
                                if (CheckRemoteMachineInstallPath(installpath, remoteName))
                                {
                                    strGenSubKey = uninstallKey;    // The install key node.
                                    strRemoteMCGenInsPath = installpath;    // The Gen app installed path on remote machine.    
                                }
                                
                            }
                        }
                    }
                }
                environmentKey.Close();
                return  strRemoteMCGenInsPath;
            }
            catch (Exception xe)
            {
                string sXE = xe.Message;
                return sXE;
            }
        }

4. 读取远程机某文件版本信息。

        public string GetGenAppVersion(string sRemoteIP,string strDllFilePath)
        {
            string sGenVersion;
            try
            {
                if (strDllFilePath == "No Geneva Install")
                {
                    sGenVersion = "N/A";
                }
                else
                { 

                     string sDllPath = "\\" + sRemoteIP + "\\" + strDllFilePath.Replace(":", "$") + "AppServer\\ConfigurationManager.exe"; 

                    FileVersionInfo myFileVersion = FileVersionInfo.GetVersionInfo("\\" + sDllPath);
                    
                    sGenVersion = myFileVersion.FileVersion;
                }
            }
            catch (Exception xe)
            {
                
                sGenVersion ="N/A";
            }
            
            return sGenVersion; 
        }

 5. 远程计算机系统版信息。

 public string GetRemoteOSVersion(string sRemoteName)
        {
            string sVersion;
            sVersion = "NULL";
            strKeyPath = @"SOFTWARE\Microsoft\Windows NT";
            environmentKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, sRemoteName).OpenSubKey(strKeyPath);
            lsRemoveSubKeys = environmentKey.GetSubKeyNames();

            foreach (string uninstallKey in lsRemoveSubKeys) // Ergodic the keys under uninstall and pick up the subkey which has the Gen app install path attribute value.
            {
                RegistryKey rkUninstallKey = environmentKey.OpenSubKey(uninstallKey);   // Open subkey node in order to get the attribute text.
 
                sVersion = (String)rkUninstallKey.GetValue("ProductName", String.Empty);
            }
            return sVersion;
        }
