C#操作PostgreSQL示范代码片段

先到网上下载PostgreSql.Data.PostgreSqlClient.dll
然后添加引用,使用命名空间

using PostgreSql.Data.PostgreSqlClient;
          string connectString = @"Server=localhost;Database=postgres;User ID=arwen;Password=arwen";
            PgConnection conn = new PgConnection(connectString);
            conn.Open();
            PgCommand cmd = conn.CreateCommand();
            cmd.CommandText = "select * from test";
            cmd.CommandType = CommandType.Text;
            using (PgDataReader reader = cmd.ExecuteReader())
            {
                while (reader.Read())
                    Console.WriteLine(reader[0].ToString());
            }
