Question

请解释一下此代码意思 string strConn = "server=.;database=LandDB;uid=sa;pwd=123456"; string

//string strConn = "server=.;database=LandDB;uid=sa;pwd=123456"; string strConn = ConfigurationManager.ConnectionStrings["LandDBConnectionString"].ConnectionString; SqlConnection conn = new SqlConnection(strConn); conn.Open(); string sql="insert into T_bl_canton_code(Cin_code,Cin_name,Gov_name,Land_dp_name,Parent_code) values('"+s1+"','"+s2+"','"+s3+"','"+s4+"',

Answer 1

strConn是用于数据库连接的，database=LandDB表明你用了LandDB这个数据库；uid=sa;pwd=123456就是登陆数据库的用户名和密码，conn是建立数据库连接，sql是查询语句。
