興趣使然，啊不就這樣，也就這樣！

今天要跟大家分享的是如何從檔案路徑提取檔名

可以利用openFileDialog抓取路徑後使用

並且也移除附檔名

string filename = "C:\\MyDirectory\\MyFile.bat"; // Remove directory if present. // Do this before extension removal incase directory has a period character. const size_t last_slash_idx = filename.find_last_of("\\/"); if (std::string::npos != last_slash_idx) { filename.erase(0, last_slash_idx + 1); } // 移除附檔名 const size_t period_idx = filename.rfind('.'); if (std::string::npos != period_idx) { filename.erase(period_idx); }
