1.使用C#获取当前程序或解决方案的路径 2.使用C#获取当前登录用户的相关目录 3.也可以获取当前系统通用目录 4.获取Windows系统的目录，从注册表中获取。 一、当前用户的目录，HKEY_Current_User 二、系统通用目录，当前机器,Hkey_Local_Machine
三、代码实例
class LocalPathHelper { //windows当前用户的注册表键 private static RegistryKey folders; /// <summary> /// 全局指定当前获取注册表的根节点 /// 一般只有管理员身份运行，才能操作Registry.LocalMachine 对应的文件 /// </summary> public static RegistryKey RootKey { get; set; } static LocalPathHelper() { SetAsCurrentUser(); } /// <summary> /// 设置根节点为LocalMachine /// </summary> public static void SetAsLocalMachine() { RootKey = Registry.LocalMachine; folders = OpenRegistryKey(Registry.LocalMachine, @"/software/microsoft/windows/currentversion/explorer/shell folders"); } /// <summary> /// 设置根节点为LocalMachine /// </summary> public static void SetAsCurrentUser() { RootKey = Registry.CurrentUser; folders = OpenRegistryKey(Registry.CurrentUser, @"/software/microsoft/windows/currentversion/explorer/shell folders"); } #region 当前用户路径 /// <summary> /// windows用户字体目录路径 /// </summary> public static string FontsPath { get { return GetPath("Fonts"); } } /// <summary> /// windows用户网络邻居路径 /// </summary> public static string NetHoodPath { get { return GetPath("Nethood"); } } /// <summary> /// windows用户我的文档路径 /// </summary> public static string PersonalPath { get { return GetPath("Personal"); } } /// <summary> /// windows用户最近访问文档快捷方式目录 /// </summary> public static string RecentPath { get { return GetPath("Recent"); } } /// <summary> /// windows用户发送到目录路径 /// </summary> public static string SendToPath { get { return GetPath("Sendto"); } } /// <summary> /// windows用户收藏夹目录路径 /// </summary> public static string FavoritesPath { get { return GetPath("Favorites"); } } /// <summary> /// windows用户网页历史目录路径 /// </summary> public static string HistoryPath { get { return GetPath("History"); } } /// <summary> /// windows用户cookies目录路径 /// </summary> public static string CookiePath { get { return GetPath("Cookies"); } } /// <summary> /// windows用户Cache目录路径 /// </summary> public static string CachePath { get { return GetPath("Cache"); } } #endregion #region //系统路径 /// <summary> /// widnows用户桌面路径 /// </summary> public static string DesktopPath { get { return GetPath("Desktop"); } } /// <summary> /// windows用户开始菜单程序路径 /// </summary> public static string ProgramsPath { get { return GetPath("Programs"); } } /// <summary> /// windows用户开始菜单目录路径 /// </summary> public static string StartMenuPath { get { return GetPath("StartMenu"); } } /// <summary> /// windows用户开始菜单启动项目路径 /// </summary> public static string StartupPath { get { return GetPath("Startup"); } } /// <summary> /// windows用户应用程序数据目录 /// </summary> public static string AppdataPath { get { return GetPath("Appdata"); } } /// <summary> /// 公共文档 /// </summary> public static string Documents { get { return GetPath("Documents"); } } #endregion /// <summary> /// 当前应用程序的工作目录，不是程序文件目录 /// </summary> public static string CurrentProgramPath { get { return Directory.GetCurrentDirectory(); } } /// <summary> /// 当前应用程序解决方案路径 /// </summary> public static string CurrentSolutionPath { get { string program = CurrentProgramPath; DirectoryInfo info = new DirectoryInfo(program); return info.Parent.Parent.FullName; } } #region //私有方法 /// <summary> /// 获取键值对应的文件夹 /// </summary> /// <param name="key">键</param> /// <returns>值</returns> private static string GetPath(string key) { if (RootKey == Registry.LocalMachine) key = "Common " + key; string path = folders.GetValue(key).ToString(); if (!string.IsNullOrEmpty(path)) { if (Directory.Exists(path)) { return path; } } return "'" + key + "'对应的文件夹不存在"; } //打开，指定根节点和路径的注册表项 private static RegistryKey OpenRegistryKey(RegistryKey root, string str) { str = str.Remove(0, 1) + @"/"; while (str.IndexOf(@"/") != -1) { root = root.OpenSubKey(str.Substring(0, str.IndexOf(@"/"))); str = str.Remove(0, str.IndexOf(@"/") + 1); } return root; } #endregion }
