获取系统中安装的应用程序的基本信息

  当要实现获取系统中安装的应用程序基本信息时，很多人可能都会想到从注册表HKEY_CURRENT_USER/Software/Microsoft/Windows/CurrentVersion/Uninstall里取，但这样会有几个弊端：1，取的应用程序不全。2，有的程序他没有安装路径只有卸载路径。3，有的程序获取不到Icon。为了解决问题1，我们可以想想咱们安装的程序在开始菜单=》所有程序中都会列出来。所以我们可以从这入手，获取开始菜单里的所有程序，当您打开开始菜单程序所在的文件夹时，发现里面全部是快捷方式。然后再看看右键快捷方式的属性，正好，启动路径和图标都有。这样那三个问题都可以帮我们解决了。

  现在就把代码奉上,一起学习，一起进步：

public static void LoadAppList(List<string> appNames, List<string> appPaths) { string allUserStartMenuPath = GetAllUsersStartMenuPath() + "//"; string admStartMenuPath = GetUsersStartMenuPath() + "//"; IShellLink shellLink = (IShellLink)new ShellLink(); UCOMIPersistFile vPersistFile = shellLink as UCOMIPersistFile; List<string> temp = new List<string>(); List<string> appLnks = new List<string>(); GetInfo(appNames, appLnks, allUserStartMenuPath); GetInfo(appNames, appLnks, admStartMenuPath); for (int j = 0; j < appLnks.Count; j++) { //获取快捷键运行路径 vPersistFile.Load(appLnks[j], 0); StringBuilder stringBuilder = new StringBuilder(300); WIN32_FIND_DATA vWIN32_FIND_DATA; shellLink.GetPath(stringBuilder, stringBuilder.Capacity, out vWIN32_FIND_DATA, SLGP_FLAGS.SLGP_RAWPATH); string appPath = stringBuilder.ToString(); //过滤不想要的程序 if (!appPath.ToLower().Contains("exe") || appPath.ToLower().Contains("unins") || appPath.ToLower().Contains("tool") || appPath.ToLower().Contains("config") || appPath.ToLower().Contains("{") || appPath.ToLower().Contains("%") || appPath.ToLower().Contains("plug") || appPath.ToLower().Contains("activex") || appPath.ToLower().Contains("help") || appPath.ToLower().Contains("extension") || appPath.ToLower().Contains("driver") || appPath.ToLower().Contains("system32") || appPath.ToLower().Contains("update") || appPath.ToLower().Contains("cmd") || appPath.ToLower().Contains("ati")) { continue; } if (appNames[j].ToLower().Contains("command") || appNames[j].ToLower().Contains("卸载") || appNames[j].ToLower().Contains("logg") || appNames[j].ToLower().Contains("unins") || appNames[j].ToLower().Contains("setting") || appNames[j].ToLower().Contains("wizard") || appNames[j].ToLower().Contains("debugger") || appNames[j].ToLower().Contains("idea touch") || appNames[j].ToLower().Contains("touch-out")) { continue; } if (temp.Contains(appPath)) { continue; } temp.Add(appPath); appPaths.Add(appPath); } } //获取当前文件夹下所有的快捷方式的名称和路径 private static void GetInfo(List<string> appNames, List<string> appLnks, string path) { DirectoryInfo userFolder = new DirectoryInfo(path); foreach (DirectoryInfo NextFolder in userFolder.GetDirectories()) { if (NextFolder.Name.ToLower() == "touch game") { continue; } if (NextFolder.Attributes == FileAttributes.ReadOnly) { continue; } foreach (DirectoryInfo innerFolder in NextFolder.GetDirectories()) { GetInfo(appNames, appLnks, NextFolder.FullName); } foreach (FileInfo NextFile in NextFolder.GetFiles()) { if (NextFile.Extension.ToLower() != ".lnk") { continue; } string name = NextFile.Name.Substring(0, NextFile.Name.LastIndexOf(".")); if (appNames.Contains(name)) { continue; } appNames.Add(name); appLnks.Add(NextFile.FullName); } } foreach (FileInfo NextFolder in userFolder.GetFiles()) { if (NextFolder.Name.ToLower() == "touch game") { continue; } if (NextFolder.Extension.ToLower() != ".lnk") { continue; } string name = NextFolder.Name.Substring(0, NextFolder.Name.LastIndexOf(".")); if (appNames.Contains(name)) { continue; } appNames.Add(name); appLnks.Add(NextFolder.FullName); } }

 

下面是在网上找的一些获取快捷方式信息的方法：

 将上下两段代码放在一个类文件即可。。
