Shortcuts can be manipulated using the COM objects in SHELL32.DLL.
In your Visual Studio project, add a reference to the COM library "Microsoft Shell Controls And Automation" and then use the following:
/// <summary>
/// Returns whether the given path/file is a link
/// </summary>
/// <param name="shortcutFilename"></param>
/// <returns></returns>
public static bool IsLink(string shortcutFilename)
{
string pathOnly = System.IO.Path.GetDirectoryName(shortcutFilename);
string filenameOnly = System.IO.Path.GetFileName(shortcutFilename);
Shell32.Shell shell = new Shell32.ShellClass();
Shell32.Folder folder = shell.NameSpace(pathOnly);
Shell32.FolderItem folderItem = folder.ParseName(filenameOnly);
if (folderItem != null)
{
return folderItem.IsLink;
}
return false; // not found
}
You can get the actual target of the link as follows:
/// <summary>
/// If path/file is a link returns the full pathname of the target,
/// Else return the original pathnameo "" if the file/path can't be found
/// </summary>
/// <param name="shortcutFilename"></param>
/// <returns></returns>
public static string GetShortcutTarget(string shortcutFilename)
{
string pathOnly = System.IO.Path.GetDirectoryName(shortcutFilename);
string filenameOnly = System.IO.Path.GetFileName(shortcutFilename);
Shell32.Shell shell = new Shell32.ShellClass();
Shell32.Folder folder = shell.NameSpace(pathOnly);
Shell32.FolderItem folderItem = folder.ParseName(filenameOnly);
if (folderItem != null)
{
if (folderItem.IsLink)
{
Shell32.ShellLinkObject link = (Shell32.ShellLinkObject)folderItem.GetLink;
return link.Path;
}
return shortcutFilename;
}
return ""; // not found
}
