先获得目录里的所有文件名，然后排序输出即可。

代码 #

var directoryName = Console.ReadLine();
if (!Directory.Exists(directoryName))
{
    Console.WriteLine(directoryName + " doesn't exist or isn't a directory");
    return;
}

var directoryFiles = Directory.GetFiles(directoryName);
Array.Sort(directoryFiles);
for (var i = 0; i < directoryFiles.Length; i++)
    Console.WriteLine(directoryFiles[i]);
