如何获取一个目录下包含子目录内的所有文件名，并保存在一个数组中或XML文档里

private   void   getDirectories(string   path) 

{ 

string[]   fileNames   =   Directory.GetFiles(path); 

string[]   directories   =   Directory.GetDirectories(path); 

foreach   (string   file   in   fileNames) 

{ 

Console.WriteLine( "Filename:{0} ",file); 

} 

foreach   (string   dir   in   directories) 

{ 

Console.WriteLine( "Directoriesname:{0} ",dir); 

getDirectories(dir); 

} 

} 



Console.WriteLine这个地方你可以换成arraylist

 

或

可以参考我以前写的一个类，生成xml文件。
