C# 连接SQLite ODBC driver

using System.Data.Odbc;//in order to use database

private void button_login_Click(object sender, EventArgs e)
        {
            string strSqlQuery = string.Format("select * from USER where username=‘{0}‘;",textBox_username.Text);
            string connStr = "";
            connStr += "Dsn=SQLite3 Datasource;database=D:\\database\\jiche.db;StepAPI=0;SyncPragma=;NoTXN=0;Timeout=;ShortNames=0;LongNames=0;NoCreat=0;NoWCHAR=0;FKSupport=0;JournalMode=;OEMCP=0;LoadExt=;BigInt=0;JDConv=0;";
            //cnStr += "Driver={SQLite3 ODBC Driver};database=D:\\database\\jiche.db;StepAPI=0;SyncPragma=;NoTXN=0;Timeout=;ShortNames=0;LongNames=0;NoCreat=0;NoWCHAR=0;FKSupport=0;JournalMode=;OEMCP=0;LoadExt=;BigInt=0;JDConv=0;";

            OdbcConnection conn = new OdbcConnection(connStr);
            OdbcDataAdapter da = new OdbcDataAdapter(strSqlQuery, conn); //引用数据库连接dbconn并依据SQL语句"select * from kaizhi"创建OleDbDataAdapter对象da
            DataSet ds = new DataSet(); //创建DataSet对象
            da.Fill(ds);
            if(ds.Tables[0].Rows.Count>=1)
            {
                if (ds.Tables[0].Rows[0]["password"].ToString() == textBox_password.Text)
                {
                    //MessageBox.Show("登陆成功");
                    FormMain form_main = new FormMain(this);
                    form_main.Show();
                    this.Hide();
                }

            }
        }

今天早晨试了一下，用oledb连不上，换成odbc就好了。
