如果路径/文件是快捷方式,我如何以编程方式进行测试？

我需要测试文件是否是快捷方式.我仍在试图弄清楚将如何设置内容,但我可能只有它的路径,我可能只有文件的实际内容(作为byte [])或者我可能同时拥有它们.

一些复杂性包括我可以在一个zip文件中(在这种情况下,路径将是一个内部路径)

可以使用SHELL32.DLL中的COM对象来操作快捷方式.

在Visual Studio项目中,添加对COM库"Microsoft Shell Controls And Automation"的引用,然后使用以下命令:

/// 

/// Returns whether the given path/file is a link
/// 
/// 
/// 
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
}

您可以按如下方式获取链接的实际目标:

    /// 

    /// 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
    /// 
    /// 
    /// 
    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
    }
