這篇文章主要介紹了C#如何操作SQLite實現(xiàn)數(shù)據(jù)的增刪改查，具有一定借鑒價值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。
SQLite是一個輕量級、跨平臺的關系型數(shù)據(jù)庫，在小型項目中，方便，易用，同時支持多種開發(fā)語言，下面是我用C#語言對SQLite 的一個封裝。
Winfrom界面如下：
代碼還需要改進部分：
下面的代碼我不覺得是完美的，讀者可以自己去實現(xiàn)這些功能：
1.如果不想用多線程可以去掉UsingLock.cs ，在SQLiteHelper.cs中刪除對應的引用即可。
2.創(chuàng)建數(shù)據(jù)庫文件，可以從代碼中分離成單獨的方法。比如創(chuàng)建有密碼的數(shù)據(jù)庫文件。
3.在執(zhí)行SQL語句時，有些語句執(zhí)行成功，也不會有影響行數(shù)。比如，創(chuàng)建表，刪除表，此時執(zhí)行SQL語句返回的影響行數(shù)就為0。
4.只要SQL語句不報錯就是執(zhí)行成功的，在方法的返回值可以改為多個，比如用
Tuple<bool, string, int> 第一個參數(shù) bool 代表執(zhí)行結果，第二個參數(shù) string 代表錯誤信息，第三個參數(shù) int 代表影響的行數(shù)。
同樣，也可以這樣：
Tuple<bool, string, DataSet> 第一個參數(shù) bool 代表執(zhí)行結果，第二個參數(shù) string 代表錯誤信息，第三個參數(shù) DataSet 代表返回的表單數(shù)據(jù)。
