文件搜索的实现（深度搜索）

System.Collections.Stack stackFile = new Stack(); ///

/// 把要搜索的路径的文件夹全部压栈 /// ///
  public Stack FileList(string path)
{ string[] files = System.IO.Directory.GetDirectories(path);
foreach(string file in files)
{ stackFile.Push(file); FileList(file); }
 return stackFile; } ///

/// 把所有符合搜索条件的文件放到一个ArrayList里 /// /// 搜索的路径 /// 要搜索的文件 ///
 public ArrayList SearchFile(string path,string filter)
{ ArrayList array = new ArrayList(); Stack stack = new Stack(); //-----------对根目录进行搜索
string[] Rootfiles = System.IO.Directory.GetFileSystemEntries(path,filter);
foreach(string file in Rootfiles)
{ System.IO.DirectoryInfo dirInfo = new DirectoryInfo(file); array.Add(dirInfo); } //----------- stack = this.FileList(path);
if(stack.Count > 0)
{ while(stack.Count > 0)
{ string CurrentFile = stack.Pop().ToString();
string[] files = System.IO.Directory.GetFileSystemEntries(CurrentFile,filter);
foreach(string file in files) { System.IO.DirectoryInfo dirInfo = new DirectoryInfo(file); array.Add(dirInfo); } } }
return array; }
