hello experts,

i'm using postgresql function to get data to a .NET application.
so far i succeed to accumulate my datas in a type created in psql. Now, i recover values with npgsql, i pass a executeScalar as i have all function response in only one line.
when i recover datas with npgsql i have all them in the first cell of the datatable.
here's what my postgresql looks like, this response has three rows.


what would be an elegant way to recover my values as i need to output them to csv file.
 should i parse the string and create my lines ? if so what lib would help, is there something like XML parser but for postgresql responses ?
or is there a way to get the answer of postgres query in a better recovery solution with npgsql ?

thank you in advance for help.
