Visual studio 2010及以上版本,连接SQLite数据库
1、在Sqlite开发站点下载SQLite的.exe安装包
Ctrl+F搜索这条语句:This is the only setup package that is capable of installing the design-time components for Visual Studio xxxx
找到对应的VS版本,注意一定要带bundle,集成了设计器;无论32位系统还是64位系统,似乎都要下载32位的(X86)
如下图:
否则,在Visual Studio中想添加新数据库时没有Sqlite这个选项,下载正确并安装后,在VS中可看到SQLite:
2、连接数据库
添加连接--database:db文件
2、VS2010 在窗体中拉一个按钮和DataGridView,实现点击按钮,在DataGridView显示数据库中的数据
private void button1_Click(object sender, EventArgs e) { using (SQLiteConnection con = new SQLiteConnection(Constants.DATA_SOURCE)) { con.Open(); using (SQLiteCommand cmd = new SQLiteCommand()) { cmd.Connection = con; cmd.CommandText = string.Format("select * from jy_cdjy_cdjyhgz"); int rows = cmd.ExecuteNonQuery(); SQLiteDataAdapter oraDA = new SQLiteDataAdapter(cmd); DataSet ds = new DataSet(); oraDA.Fill(ds); //con.Close(); DataTable dtbl = ds.Tables[0]; this.dataGridView1.DataSource = dtbl; } } }
