列出C盘下所有文件的函数

[heaven33]

请问用c++写一个列出c盘下所有文件的函数，怎么写？

2楼真是简明扼要，在下佩服，试了下，可以

2楼的 用的是什么函数? 感觉是调用系统命令阿

[wokao112358]

不过好像不符合题目要求，还是用递归吧

[kiuyongfa218]

使用find_first,findnext使用递归，列出所有文件。

[baihacker]

typedef	void 	(*ENUM_FILES_FUNCTION)(const TCHAR*, LPWIN32_FILE_ATTRIBUTE_DATA);
		
		#define	SYS_IS_DIRECTORY(f) 	(f & FILE_ATTRIBUTE_DIRECTORY)
		#define	SYS_IS_HIDDEN(f) 	(f & FILE_ATTRIBUTE_HIDDEN)
		#define	SYS_IS_READONLY(f) 	(f & FILE_ATTRIBUTE_READONLY)
		#define	SYS_IS_SYSTEM(f) 	(f & FILE_ATTRIBUTE_SYSTEM)
		extern	void	EnumFiles(const TCHAR*, ENUM_FILES_FUNCTION);

void	EnumFiles(const TCHAR* szSourceDir, ENUM_FILES_FUNCTION callback_fun)
		{
			if (!szSourceDir) return;
			
			WIN32_FIND_DATA				FindFileData;   
			WIN32_FILE_ATTRIBUTE_DATA		FindFileAttr;
			HANDLE   hFind  =			INVALID_HANDLE_VALUE;
			TCHAR	currDir[MAX_PATH];
			TCHAR	Result[MAX_PATH];
			
			_tcsncpy(currDir, szSourceDir, _tcslen(szSourceDir) + 1);   
			_tcsncat(currDir, _T("\\*"), 3);
			
			hFind = FindFirstFile(currDir, &FindFileData);   
			
			if (hFind == INVALID_HANDLE_VALUE)     	return;
			do 
			{
				if (*FindFileData.cFileName == '.') continue;
				::_stprintf(Result, _T("%s\\%s"), szSourceDir, FindFileData.cFileName);
				if (callback_fun && GetFileAttributesEx(Result, GetFileExInfoStandard, &FindFileAttr))
				{
					
					(*callback_fun)(Result, &FindFileAttr);
				}
			} while (FindNextFile(hFind, &FindFileData));	
		}

#include <windows.h>
void main()
{
 const char *command = "dir c:\\";
 system(command);
 system("pause");
}

[大前置]

递归

[sunnywyg]

2楼的只能列一级目录吧?要把所有的文件找出来,应该是只能递归,不过估计要很久...

[gykgod]

参考MFC的CFileFind

[woods2001]

用命令行参数

[yuyunliuhen]

    ZeroMemory(&Filedata,sizeof(Filedata));

    //save current path to a strPathName variable
    _tcscpy(strPathName,strDirectoryName);

    //add a \ to the end of strPathName
    if (strPathName[_tcslen(strPathName)-1] != _T('\\'))
    {
        _tcscat(strPathName,_T("\\"));
    }
    //add a * to the end of strPathName
    _tcscat(strPathName,_T("*.*"));

    //find the first file in the directory,if succeeds,return value is a search handle used in a subsequent call to FindNextFile or FindClose.

写一个跨平台的吧，查询指定路径下所有文件包括路径。
