access数据库和SQLite数据库速度的简单对比

先上一张结果图,用了4种方式,分别插入10000条数据,可以看到差别还是很大的,如果插入更多数据的话,估计速度还会差更大

这是源代码

string AccessConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + Environment.CurrentDirectory + "\\TestDB.accdb";

        string SQLiteConn = "Data Source=" + Environment.CurrentDirectory + "\\Test.db";

        }

            for(int i=1;i<=II;i++)

            {

                Cmd.ExecuteNonQuery();

                Application.DoEvents();

                Lab3.Text = (i / II) * 100 + " %";

            }
