目的：实现用CreateDirectory创建多级目录

1.引入静态库

#include "shlwapi.h"#pragma comment(lib,"shlwapi.lib")

2.函数

const wchar_t* wcstrrchr(const wchar_t* str, const wchar_t wc) { const wchar_t* pwc = NULL; for (int i=wcslen(str)-1;i>=0;i--) { if (str[i] == wc) { pwc = str + i; break; } } return pwc; } bool createMultiDir(const wchar_t* path) { if (path == NULL) return false; const wchar_t* pwcStrrchr = wcstrrchr(path,L'\\'); if (!pwcStrrchr) return false; if (PathIsDirectory(path)) return true; wchar_t wsSubPath[MAX_PATH] = {}; memset(wsSubPath,0,sizeof(wsSubPath)); for (int i=0; i<pwcStrrchr-path; i++) wsSubPath[i] = *(path+i); createMultiDir(wsSubPath); if(CreateDirectory(path,NULL)) return true; return false; }

3.调用案例

createMultiDir(L"d:\\whish\\test\\好孩子\\宝马\\测试.txt"); //绝对路径createMultiDir(L".\\whish\\test\\好孩子\\宝马\\测试.txt");//相对路径
