Accessing Custom Attributes Using Reflection in C#

Accessing Custom Attributes Using Reflection in C#

Custom attributes provide a powerful way to attach declarative metadata to your code-whether it’s on classes, methods, properties, or fields. But how do you actually read that metadata at runtime?

This is where Reflection shines.

By using the System.Reflection, you can dynamically inspect your code’s structure and retrieve the information defined within those custom attributes. This functionality is the backbone for creating highly flexible applications, such as automated validation frameworks, custom JSON serializers, or dynamic API routing systems.

With just a few lines of Reflection code, your application can intelligently adapt its behavior based entirely on the metadata you’ve applied.
