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("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：
