Specifying the database name in the connection string?

Question

PostgreSQL

A question. I want to check whether it exists before connecting to the database. However, the connection string implies that you need to specify the name of the database to be used.

NpgsqlConnection conn = new NpgsqlConnection("Server=127.0.0.1;Port=5432;User Id=postgres;Password=admin;Database=XXXXXX;");

How to be?

Answer 1

NpgsqlConnection conn = new NpgsqlConnection("Server=127.0.0.1;Port=5432;User Id=postgres;Password=admin;");
var databasesTable = conn.GetSchema("Databases", null);
// проверяем наличие базы данных в таблице databasesTable
