CAD .net开发-从注册表中获取CAD安装路径

32位系统：

RegistryKey keyLocalMachine = Registry.LocalMachine;

64位系统：

Microsoft.Win32.RegistryKey keyLocalMachine = Microsoft.Win32.RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, Microsoft.Win32.RegistryView.Registry64);

public static List GetAutoCADLocations()
        {
            //用于存储系统中安装的AutoCAD路径列表
            List locations = new List();
            // 获取HKEY_LOCAL_MACHINE键
            //RegistryKey keyLocalMachine = Registry.LocalMachine;
            RegistryKey keyLocalMachine = Microsoft.Win32.RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, Microsoft.Win32.RegistryView.Registry64);
            // 打开AutoCAD所属的注册表键:HKEY_LOCAL_MACHINESoftwareAutodeskAutoCAD
            RegistryKey keyAutoCAD = keyLocalMachine.OpenSubKey("Software\Autodesk\AutoCAD");
            //获得表示系统中安装的各版本的AutoCAD注册表键
            string[] cadVersions = keyAutoCAD.GetSubKeyNames();
            foreach (string cadVersion in cadVersions)
            {
                //打开特定版本的AutoCAD注册表键
                RegistryKey keyCADVersion = keyAutoCAD.OpenSubKey(cadVersion);
                //获取表示各语言版本的AutoCAD注册表键值
                string[] cadNames = keyCADVersion.GetSubKeyNames();
                foreach (string cadName in cadNames)
                {
                    if (cadName.EndsWith("804"))//中文版本
                    {
                        //打开中文版本的AutoCAD所属的注册表键
                        RegistryKey keyCADName = keyCADVersion.OpenSubKey(cadName);
                        //获取AutoCAD的安装路径
                        if (keyCADName.GetValue("Location") != null)
                        {
                            string location = keyCADName.GetValue("Location").ToString();
                            locations.Add(location);//将路径添加到列表中
                        }
                        
                    }
                }
            }
            return locations;//返回系统中安装的AutoCAD路径列表
        }
