请问：如何用API得到一个指定目录的所有文件

主如果应用FindFirst()、FindNext()来查找所有的文件：

Var

Path:String//指定的目次

SearchRec:

TSearchRec

while

FindNext(SearchRec)=0

do

Slist.Add(SearchRec.Name)

Slist:=

TStringList.Create()

Slist:

TStringList

begin

if

FindFirst(Path,faAnyFile,SearchRec)=0

then

begin

Slist.Add(SearchRec.Name)

end

FindClose(SearchRec)

end

//如许Slist里就记录了所有的文件名(包含路径)

没有文件列表，只能枚举所有文件，再根据文件的属性判断是文件或者文件夹。

下面是MSDN上的完整例子

#include <windows.h>

#include <tchar.h>

#include <stdio.h>

#include <strsafe.h>
