VC++(MFC) 繁中/簡中字串 (CString) 檔案寫入/讀取 不亂碼 [2018/08/21在VC2015測試過] 資料來源: http://aigo.iteye.com/blog/2299351 https://blog.csdn.net/Augusdi/article/details/8961008 [ MFC使用CFile读写Unicode字符集文件（文件头缺失导致乱码）/ MFC使用CFile读写Unicode字符集文件] 寫入: #include #ifndef _UNICODE #define _UNICODE //使用UNICODE编码 #endif #include //为了使用CString类 const int UNICODE_TXT_FLG = 0xFEFF; //UNICODE文本标示 int main() { FILE* WriteF; CString Wstr = _T("一个测试写入文本"); WriteF = fopen("test.txt","w+"); if(WriteF) { fwrite(&UNICODE_TXT_FLG,2,1,WriteF); //写入头部 fwrite(Wstr.GetBuffer(Wstr.GetLength()),Wstr.GetLength() * 2,1,WriteF); fclose(WriteF); } return 0; } 讀取: CFile ReadF(L"test.txt", CFile::modeRead); TCHAR* temp = new TCHAR[ReadF.GetLength() / 2 + 1]; ReadF.Read(temp, ReadF.GetLength()); temp[ReadF.GetLength() / 2] = 0; ReadF.Close(); strVal = temp;
