Hallo,

I'm using Npgsql to establish a connection to my PostgreSQL database. Now I want to save a file (using a file upload control).
How can I save this file in my database? How can I use large objects or is there any other possibility?

Thanks

You can use a bytea field type.

In our user manual, you will find an example which writes a file to the database and reads it back. I think you can use it as a base start for your work.

I hope it helps.

Thanks.
As next step I want to try out large objects. Does it work when the files are stored on the webserver and not on the postgreSQL server?
