我想在C,Windows中删除目录。我了解我必须首先删除目录中的所有文件,这是我很困惑的部分。尽管我不了解如何从文档中实现它们,但我找到了SHFileOperation
和IFileOperation
。
我当前的实现:
int dir_exists = 0;
snprintf(dir_name, STR_SIZE, "%s\\%s", LOCAL_DIR, tokens[1]);
// Check if directory exists
DWORD dwAttrib = GetFileAttributes(dir_name);
if (dwAttrib != INVALID_FILE_ATTRIBUTES && (dwAttrib & FILE_ATTRIBUTE_DIRECTORY)) {
dir_exists = 1;
}
if (dir_exists == 1) {
// Remove contents of directory (CURRENTLY UNIX)
DIR *dir;
struct dirent *d;
char filepath[FNAME_SIZE];
dir = opendir(dir_name);
while (d = readdir(dir)) {
sprintf(filepath, "%s/%s", dir_name, d->d_name);
remove(filepath);
}
// Remove directory
if ((RemoveDirectory(dir_name)) == 0) {
printf("Error removing dictionary\n");
return 0;
}
}
我想要Windows替换不使用
#include <dirent.h>
的注释部分,因为我的VS没有此头文件:// Remove contents of directory (CURRENTLY UNIX)

如解决方案所述,使用此功能时请小心,并确保将null终止pFrom
设为双倍。
dir_name[STR_SIZE];
int dir_exists = 0;
snprintf(dir_name, STR_SIZE, "folder/dir_to_be_deleted");
// Check if directory exists
DWORD dwAttrib = GetFileAttributes(dir_name);
if (dwAttrib != INVALID_FILE_ATTRIBUTES && (dwAttrib & FILE_ATTRIBUTE_DIRECTORY)) {
dir_exists = 1;
}
if (dir_exists == 1) {
// Remove contents of directory
snprintf(dir_name, STR_SIZE, "%s/%s", LOCAL_DIR, tokens[1]);
TCHAR szDir[MAX_PATH];
StringCchCopy(szDir, MAX_PATH, dir_name);
StringCchCat(szDir, MAX_PATH, TEXT("\\*"));
int len = _tcslen(szDir);
TCHAR* pszFrom = malloc((len + 4) * sizeof(TCHAR)); //4 to handle wide char
StringCchCopyN(pszFrom, len + 2, szDir, len + 2);
pszFrom[len] = 0;
pszFrom[len + 1] = 0;
SHFILEOPSTRUCT fileop;
fileop.hwnd = NULL; // no status display
fileop.wFunc = FO_DELETE; // delete operation
fileop.pFrom = pszFrom; // source file name as double null terminated string
fileop.pTo = NULL; // no destination needed
fileop.fFlags = FOF_NOCONFIRMATION | FOF_SILENT; // do not prompt the user
fileop.fAnyOperationsAborted = FALSE;
fileop.lpszProgressTitle = NULL;
fileop.hNameMappings = NULL;
if (SHFileOperation(&fileop) != 0) {
printf("Error SHFileOperation\n");
return 0;
}
free(pszFrom);
// Remove directory
if ((RemoveDirectory(dir_name)) == 0) {
printf("Error removing dictionary\n");
return 0;
}
}
