我使用以下函数列出文件夹内的所有项目。它将所有文件写入字符串向量中,但您可以更改它。
bool ListContents (vector<string>& dest, string dir, string filter, bool recursively)
{
WIN32_FIND_DATAA ffd;
HANDLE hFind = INVALID_HANDLE_VALUE;
DWORD dwError = 0;
// Prepare string
if (dir.back() != '\\') dir += "\\";
// Safety check
if (dir.length() >= MAX_PATH) {
Error("Cannot open folder %s: path too long", dir.c_str());
return false;
}
// First entry in directory
hFind = FindFirstFileA((dir + filter).c_str(), &ffd);
if (hFind == INVALID_HANDLE_VALUE) {
Error("Cannot open folder in folder %s: error accessing first entry.", dir.c_str());
return false;
}
// List files in directory
do {
// Ignore . and .. folders, they cause stack overflow
if (strcmp(ffd.cFileName, ".") == 0) continue;
if (strcmp(ffd.cFileName, "..") == 0) continue;
// Is directory?
if (ffd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{
// Go inside recursively
if (recursively)
ListContents(dest, dir + ffd.cFileName, filter, recursively, content_type);
}
// Add file to our list
else dest.push_back(dir + ffd.cFileName);
} while (FindNextFileA(hFind, &ffd));
// Get last error
dwError = GetLastError();
if (dwError != ERROR_NO_MORE_FILES) {
Error("Error reading file list in folder %s.", dir.c_str());
return false;
}
return true;
}

您要做的就是调整它以找到最新的文件。ffd 结构体(WIN32_FIND_DATAA 数据类型)包含 ftCreationTime、ftLastAccessTime 和 ftLastWriteTime,您可以使用它们来查找最新的文件。这些成员是 FILETIME 结构,您可以在此处找到文档:http://msdn.microsoft.com/en-us/library/windows/desktop/ms724284%28v=vs.85%29.aspx
