搜索BinaryFormatter類即可。uj5u.com熱心網友回復：
你說得太草率，最好詳細說說。uj5u.com熱心網友回復：

NET里的序列化能用,但性能不太好,體積也比較大.你可以手工序列化或使用 谷歌,facbook 等公司都有開源的序列化.uj5u.com熱心網友回復：
樓主要求,最好使用 SQLITE/ LEVELDB 保存資料庫. KEY =控制元件名 , VALUE=https://bbs.csdn.net/topics/序列化結果.如果是輕量化,可以使用 INI 檔案, 控制元件名=BASE64后的序列化結果.

uj5u.com熱心網友回復：
我用的 BinaryFormatter序列化資料后寫入指定的檔案，可是關閉后，再打開再寫入的時候就會將之前的檔案覆寫掉，致使檔案中的內容丟失，變成了新寫入的內容，該如何寫入才能在原內容后面直接追加，而不丟失原來的內容呢？uj5u.com熱心網友回復：
大佬能否教我？
uj5u.com熱心網友回復：
感覺你應該用 SQLITE/ LEVELDB 保存.
uj5u.com熱心網友回復：
謝謝您，我主要想保存在檔案中，有什么辦法嘛？
uj5u.com熱心網友回復：
工具 => NUGET => 管理解決方案的 NUGET 程式包 => 搜 LEVELDB或SQLITE .然后網上找 LEVELDB或SQLITE 的代碼即可.
