Delphi下遍历文件夹下所有文件的递归算法

{-------------------------------------------------------------------------------
过程名: MakeFileList 遍历文件夹及子文件夹
参数: Path,FileExt:string 1.需要遍历的目录 2.要遍历的文件扩展名
返回值: TStringList

USE StrUtils

Eg：ListBox1.Items:= MakeFileList( 'E:\极品飞车','.exe') ;
ListBox1.Items:= MakeFileList( 'E:\极品飞车','.*') ;
-------------------------------------------------------------------------------}
function MakeFileList(Path,FileExt:string):TStringList ;
var
sch:TSearchrec;
begin
Result:=TStringlist.Create;

if rightStr(trim(Path), 1) <> '\' then
Path := trim(Path) + '\'
else
Path := trim(Path);

if not DirectoryExists(Path) then
begin
Result.Clear;
exit;
end;

if FindFirst(Path + '*', faAnyfile, sch) = 0 then
begin
repeat
Application.ProcessMessages;
if ((sch.Name = '.') or (sch.Name = '..')) then Continue;
if DirectoryExists(Path+sch.Name) then
begin
Result.AddStrings(MakeFileList(Path+sch.Name,FileExt));
end
else
begin
if (UpperCase(extractfileext(Path+sch.Name)) = UpperCase(FileExt)) or (FileExt='.*') then
Result.Add(Path+sch.Name);
end;
until FindNext(sch) <> 0;
SysUtils.FindClose(sch);
end;
end;
