stp2y0 CommentsNewsbraziliandevs, coding, community, csharp, development, dotnet, engineering, inclusive, software

O padrão Observer é usado para notificar automaticamente múltiplos objetos quando o estado de outro objeto muda. Ele define uma relação "um-para-muitos" entre objetos, onde quando um objeto (o sujeito) muda, todos os seus observadores são notificados. É útil em situações onde várias partes do sistema precisam reagir às mudanças de um objeto, como em sistemas de eventos ou notificações. Exemplo de Código em C#: // Interface do Observador public interface IObservador { void Atualizar(string estado); } // Interface do Sujeito public interface ISujeito { void AdicionarObservador(IObservador observador); void RemoverObservador(IObservador observador); void NotificarObservadores(); } // Implementação do Sujeito public class…

Understanding InvalidOperationException in C#

stp2y0 CommentsNewscoding, community, csharp, development, dotnet, engineering, inclusive, learning, software, softwaredevelopment

What Does "InvalidOperationException" Mean? In layman's terms, an InvalidOperationException occurs when you try to perform an action that is not allowed in the current state of an object. It's like trying to drive a car without starting the engine first—you're trying to do something that isn't possible given the car's current state. Real-Life AnalogyImagine you're at a swimming pool, and there's a sign that says, "No diving in the shallow end." If you try to dive into the shallow end, a lifeguard will stop you and say, "You can't dive here; it's not safe." This is similar to what happens…

Follow practical code examples and expert advice to protect your software from potential threats. 1. Input Validation The input validation prevents any unauthorized user or their script from penetrating deeper into the code to access sensitive information. In other words, the input validation layer prevents invalid data or scripts executed in the code. public bool IsValidEmail(string email) { try { var addr = new System.Net.Mail.MailAddress(email); return addr.Address == email; } catch { return false; } } Enter fullscreen mode Exit fullscreen mode 2. Use Parameterized Queries These attacks can be simply blocked by using parametrized SQL queries instead of using…
