Microsoft Visual Studio:opendir()和readdir()，如何? [英] Microsoft Visual Studio: opendir() and readdir(), how?

问题描述

我以前在Dev-cpp中使用过这种代码:

I've used this kind of code in my Dev-cpp before:

if((dh = opendir(folder)) !== false){
    while((file = readdir(dh)) !== false){
        // do my stuff
    }
    closedir(dh);
}

但是现在我正在使用MSVC ++，但我不知道如何在其中添加这些文件，我试图在其中复制dirent.h/dir.h/errno.h，但是它又给出了另一个错误，这些错误与这些文件中的另一个包含文件有关文件...，并通过查看文件，我在那里看到mingw的东西，所以它的编译器相关吗? idk MSVC ++使用的编译器是什么，但是可以将这些文件复制粘贴到MSVC ++中并使其正常工作吗?

But now i am using MSVC++ and i dont know how to add those files there, i tried to copy dirent.h/dir.h/errno.h in there, but it gives another error relating to another included files inside those files ..., and by looking in the files i see mingw stuff there so its compiler related? idk what compiler MSVC++ uses, but is it possible to copypaste those files in MSVC++ and get it working?

我试图从MSDN中查找一些代码，但确实搞砸了，所以我希望我可以在上面使用这些功能...

I tried to look up some code from MSDN but it was really messed up, so im hoping i could use these functions above...

推荐答案

我建议使用示例代码:

HANDLE hFind;
WIN32_FIND_DATA FindFileData;

if((hFind = FindFirstFile("C:/some/folder/*.txt", &FindFileData)) != INVALID_HANDLE_VALUE){
    do{
        printf("%s\n", FindFileData.cFileName);
    }while(FindNextFile(hFind, &FindFileData));
    FindClose(hFind);
}

这确实更好，因为我可以使用"* .txt"等，这使得查找某些特定文件类型变得更加容易，之前我不得不为此编写自己的匹配函数:D

This really is better, because i can use "*.txt" etc, makes it much more easier to find some specific filetypes, earlier i had to write own match function for that :D
