该方法为可重载方法,有以下两种重载形式:public FileSystemInfo[ ] GetFileSystemInfos()public FileSystemInfo[] GetFileSystemInfos(string searchPattern)searchPattern:搜索字符串。返回值:第一种重载形式的返回值为 FileSystemInfo 项的数组。第二种重载形式的返回值为与搜索条件匹配的 FileSystemInfo 对象的数组。说明...

std::filesystem::create_directory("abc"); Seehttps://en.cppreference.com/w/cpp/filesystem/create_directory 对于mkdir,它需要const char *path而不是std::string,但是可以通过c_str()获取char指针,例如: mkdir(ss.str().c_str(), 0700);

#define FILENAME "C:windows" int main() { if (::PathFileExists(FILENAME)) cout<<"exist"; return 0; } 注意windows.h 一定要在shlwapi.h前面定义 5. 使用boost的filesystem类库的exists函数: #include <boost/filesystem/operations.hpp>
