C#操作PostgreSQL演示代碼片段

先到網上下載PostgreSql.Data.PostgreSqlClient.dll
然后添加引用,使用命名空間

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());

        }</pre>
