Reflection and custom attributes

Use Reflection via System.Reflection to inspect metadata at runtime. Retrieve types, read custom attributes, and instantiate objects or call methods dynamically.

using System;
using System.Reflection;

class Program {
    static void Main() {
        Type t = typeof(Program);
        foreach (var method in t.GetMethods()) {
            Console.WriteLine(method.Name);
        }
    }
}

How it reads

• typeof(T) retrieves the metadata definition for type T
• Reflection enables dependency injection, serialization, and dynamic routing plugins

Cloud tip: Reflection is highly versatile but incurs a performance cost; cache type lookups where possible.
