遍历指定目录下指定类型文件的函数(fatkun Fix版)

// ================================================================
// 遍历某个文件夹及子文件夹下某种文件,
// 使用说明
// _GetFileList(ListBox1.Items, 'c:\', '.doc');
// _GetFileList(MyTStringList, 'c:\', '.exe');
// 这不是万一博客的原版咧,是1L的fatkun修复的一版,且不管看不看得懂,收藏个先
// ================================================================
