Reflection

Reflection is a way to query metadata at runtime from the application program. Reflection supplies type information from the assemblies loaded into memory that you can use to create an instance of the class and also access properties and methods of the class.

For example, your application code executes a query and returns a dataset object, but your frontend accepts a custom class or model, and the model is defined during runtime. Based on the request received, reflection can be used to create the required model/class at runtime, access its properties or fields, and set their value by traversing through the resulting dataset.

Additionally, in previous sections, we learned how we can create custom attributes. So, in a scenario where you create an attribute to restrict numbers in a specific property, you can then use reflection to read the attribute, get the preceding...
