Delete/modify a shortcut by targetpath with C#

Question

We have users that rename the shortcut file on their desktop to our application. What is the best way to delete/modify the shortcut based on targetpath if the icon changes for the application? In other words, I'm having a hard time locating the file name because it keeps getting changed.

You should use FileSystemWatcher class:

Listens to the file system change notifications and raises events when a directory, or file in a directory, changes.

Infact you can exploit FileSystemWatcher.Changed, FileSystemWatcher.Created, FileSystemWatcher.Renamed , FileSystemWatcher.Deleted events to keep control on your file.

Here is an example by MSDN:

public static void Main()
{
    // Create a new FileSystemWatcher and set its properties.
    FileSystemWatcher watcher = new FileSystemWatcher();
    watcher.Path = "mypath";
    /* Watch for changes in LastAccess and LastWrite times, and
       the renaming of files or directories. */
    watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
       | NotifyFilters.FileName | NotifyFilters.DirectoryName;
    // Only watch text files.
    watcher.Filter = "*.txt";

    // Add event handlers.
    watcher.Changed += new FileSystemEventHandler(OnChanged);
    watcher.Created += new FileSystemEventHandler(OnChanged);
    watcher.Deleted += new FileSystemEventHandler(OnChanged);
    watcher.Renamed += new RenamedEventHandler(OnRenamed);

    // Begin watching.
    watcher.EnableRaisingEvents = true;

    // Wait for the user to quit the program.
    Console.WriteLine("Press \'q\' to quit the sample.");
    while(Console.Read()!='q');
}

// Define the event handlers.
private static void OnChanged(object source, FileSystemEventArgs e)
{
    // Specify what is done when a file is changed, created, or deleted.
   Console.WriteLine("File: " +  e.FullPath + " " + e.ChangeType);
}

private static void OnRenamed(object source, RenamedEventArgs e)
{
    // Specify what is done when a file is renamed.
    Console.WriteLine("File: {0} renamed to {1}", e.OldFullPath, e.FullPath);
}
