C#引用System.Data.SQLite操作SQLite数据库一例

环境安装SQLite.NET

引用内容

Create TABLE admin(username text,age integer);

下边用C#演示下如何对SQLite数据库进行记录的增、查、改、删操作：

程序代码
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SQLite; //引用System.Data.SQLite

public partial class Sqlite : System.Web.UI.Page
{
  protected void Page_Load(object sender, EventArgs e)
  {
  string _connectionString = @"Data Source=F:/mzwucom/bbs/db1.db";
  string _sql;

  SQLiteConnection conn = new SQLiteConnection();
  SQLiteCommand cmd;
  SQLiteDataReader dr;
  conn.ConnectionString = _connectionString;
  conn.Open();
  _sql = "insert into admin(username,age) values('user" + (new Random()).Next(1,100) + "',22)";
  cmd = new SQLiteCommand(_sql, conn);
  cmd.ExecuteNonQuery();
  _sql = "select * from admin";
  cmd = new SQLiteCommand(_sql, conn);
  dr = cmd.ExecuteReader();
  while (dr.Read())
  {
  Response.Write(dr["username"].ToString() + "," + dr["age"].ToString() + "<br/>");
  }
  }
}
