Eu tenho um arquivo de classe personalizado em C # que eu herdei e estendi parcialmente. Estou tentandore factor agora, pois tenho conhecimento suficiente para saber isso com algo como genéricos (Eu acho) eu poderia condensar bastante essa class

omo um desenvolvedor solo inexperiente, eu aprecio muito qualquer direção ou crítica construtiva que alguém possa fornece

Não seja gentil! Agradeço seu tempo e tenha um dia abençoado! Sinto muito pela duração.
