string searchPattern="22*";
public static string[] GetFiles(string path, string searchPattern, SearchOption searchOption)
{ 
        return System.IO.Directory.GetFiles(path, searchPattern, searchOption);
}

var d = new DirectoryInfo("PATH-TO-YOUR-FILES");
var files = d.GetFiles().Where(f => f.Name.StartsWith("11"));

如果需要，您可以添加更多过滤器。通过添加

You can add more filter if you want. By adding

.OrderByDescending(f=>f.CreationTime)

我将获得最新的文件。如果我不想要所有文件，我可以简单地添加

I will get newest files on top. And if I don't want all files I can simple add

.Take(10)

来获取10个最新文件，依此类推......

to get the 10 newest files and so on...
