Um Details vom Bankserver zu erhalten, werden sie mir die IP-und PORT-Nr. Ich benutze ISO8583 Nachrichtenformat (OpenIso8583 Bibliothek von NuGet Manager) zum Senden und Empfangen von Nachrichten.Bitte geben Sie mir Lösung, wie ISO8583 Nachrichten an Bank-Server mit IP-Adresse und Port-Nummer senden.Wie sende ich Nachricht im ISO8583-Format an Server mit C#
