I am trying to connect to PostgreSQL
database from my c# application like so:
NpgsqlConnection MyConnection = new
NpgsqlConnection("Server=localhost;Port=5432;User Id=postgres;Password=mypassword;Database=mydatabase;");
try
{
MyConnection.Open();
}
catch (NpgsqlException pe)
{
//Code "28P01" = user name or password is wrong
// server ip or port is wrong
}
the question is : NpgsqlException.code does not differentiate between the following conditions:
- server ip /port number is wrong
- user name and password combination is wrong
Code «28P01» is returned in both cases. obviously Npgsql can see that the server is there and responding with some data indicating bad user name or password (condition #2 above) or nobody seem to be there (condition #1 above)
how can i differentiate between those 2 cases in my code?

with Npgsql v 3.0.2.0 (not sure about older versions) if the IP/hostname is wrong an Exception with code =-2146233083 with be thrown. if however the IP/hostname is correct but the port number is wrong Exception with code= -2147467259 with be thrown. if the IP/port is correct but username /password is wrong a NpgsqlException with code = «28P01» will be thrown.

You’re probably using Npgsql 2.x; the new Npgsql 3.x throws NpgsqlException only when errors are received from a PostgreSQL server. Network connection errors are raised as SocketException etc. You’re encouraged to upgrade.
By the way: I couldn’t reproduce your exact findings even with Npgql 2.x, connecting to a wrong port or a wrong IP resulted in an NpgsqlException with Code being an empty string, not 28P01.

-
in my postgresql server, edit pg_hba.conf:
host all all 0.0.0.0/0 scram-sha-256
-
in my .net core 3.1 project, use dotnet CLI to execute the following:
dotnet-ef dbcontext scaffold "Host=192.168.0.1;Port=5432;Database=demodb;Username=demo;Password=Demo$56" Npgsql.EntityFrameworkCore.PostgreSQL
-
didn’t generate model in my project, and shell output error:
Build started...
Build succeeded.

MessageText: password authentication failed for user "demo"

28P01: password authentication failed for user "demo"
-
I test to connect postgresql by using python and navicat, npgsql lib, all is seccessful.
-
I test remove pgsql’s password, edit pg_hba.conf like this:
host all all 0.0.0.0/0 trust
then generate model by using efcore.pg is correct. -
so i think this is bug,i hope to get some help.
PS:
server:
- ip: 192.168.0.1

- soft: postgresql 12.2
workstation:
- ip: 192.168.0.2
