1.装好Postgres

2.开启远程访问

配置postgresql.conf文件

listen_addresses = '*' 

配置pg_hba.conf文件

host    all         all         0.0.0.0/0          trust

3.下载npgsql 引用2个dll

4.code

 

  string strConn = ConfigurationManager.ConnectionStrings["npgsql"].ConnectionString;

            var conn = new NpgsqlConnection(strConn);



            string sql = "select * from test";

            var dt = new DataTable();



            var cmd = new NpgsqlDataAdapter(sql, conn);



            cmd.Fill(dt);



            foreach (DataRow row in dt.Rows)

            {

                Console.WriteLine(row["xxxx"].ToString());

            }

            conn.Close();

            Console.Read();
