关于 c#:如何在 Windows 资源管理器中刷新文件的缩略图？

if (Directory.Exists(path))
{
    DirectoryInfo di = new DirectoryInfo(path);
    FileInfo[] potentiallyStubbedFiles = di.GetFiles();
    foreach (FileInfo fi in potentiallyStubbedFiles)
    {
        //ignore Thumbs.db files
        if(!fi.Name.Equals("Thumbs.db"))
        {
            Console.WriteLine("Reading" + fi.Name);
            try
            {
                FileStream fs = File.Open(fi.FullName, FileMode.Open, FileAccess.Read, FileShare.None);

                try
                {
                    //read the first byte of the file, forcing it to be unstubbed
                    byte[] firstByte = new byte[1];
                    fs.Read(firstByte, 0, 1);
                }
                catch (Exception ex)
                {
                    Console.WriteLine("An error occurred trying to read" + fi.Name +":");
                }

            }
        }
