关于判断指定路径文件是不是文件夹

[laji1601820179]

if(wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)

用这个来判断，好像有些明明是文件夹的就是判断不出来（我是要判断C：/windows下边的文件夹数目，写的程序同属性里边显示的不一样，），，，这是为什么？有更好的方法么，？

第4行 注释掉

楼主需要再加一个判断条件：判断一下文件是否可以被正确的打开。 这样就可以了。 注：foundFileName是待判断的文件的名字。 if( // a) it's a file, not a directory !(::GetFileAttributes (foundFileName) & FILE_ATTRIBUTE_DIRECTORY) && // b) it can be opened exclusively ((hFile = ::CreateFile ( foundFileName, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL)) != INVALID_HANDLE_VALUE) )

正好有个现成的函数给你参考一下

//查找目录dir下的次级目录（不嵌套），填充到outList中
void searchFileInDirectroy( const std::string& dir, std::vector<std::string>& outList )
{        
	WIN32_FIND_DATA findData;        
	HANDLE hHandle;        
	std::string filePathName;        
	std::string fullPathName;       
	filePathName = dir;        
	filePathName += "\\*.*";       
	hHandle = FindFirstFile( filePathName.c_str(), &findData );      
	if( INVALID_HANDLE_VALUE == hHandle )        
	{         
		return;        
	}        
	do        
	{         
		if( strcmp(".", findData.cFileName) == 0 || strcmp("..", findData.cFileName) == 0 ) 
		{                        
			continue;             
		}                
		fullPathName = dir;               
		fullPathName += "\\";              
		fullPathName += findData.cFileName;              
		if( findData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY )      // 是目录
		{
			outList.push_back(fullPathName);
		}               
	} 
	while( FindNextFile( hHandle, &findData ) );  
	FindClose( hHandle );
}

忘了说WIN32_FIND_DATA wfd；定义

[打你屁屁]

试试这样(fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) && strcmp(fd.cFileName, ".") && strcmp(fd.cFileName, "..")
