如何遍历某个文件夹下面的文件

string[] dirs = Directory.GetDirectories("C:/");
Array.Sort(dirs);
foreach(string s in dirs)
{
DirectoryInfo di = new DirectoryInfo(s);
Response.Write(di.Name);
}
//遍历文件
string[] files = Directory.GetFiles("C:/");
Array.Sort(files);
foreach(string s in files)
{
FileInfo fi = new FileInfo(s);
Response.Write(fi.Name);
}
