How to read BLOB from PostgreSQL in C#?

Question

PostgreSQL

The table stores data in BLOB, how to read it correctly in c#? And determine their type (numbers, strings or picture). I am using Npgsql.

Answer 1

BLOB is just an array of bytes. The content type must be known and determined in advance.
To read a BLOB, you can use a MemoryStream.
