.NET interview questions with answers: - What is the difference between Reflection and Dynamic?



  • Both reflection and dynamic are used when we want to operate on an object during runtime.

  • Reflection is used to inspect meta-data of an object. It also has the ability to invoke members of an object on runtime.

  • Dynamic is a keyword which was introduced in .NET 4.0. It evaluates object calls during runtime. So until the method calls are made compiler is least bothered if those methods / properties etc exist or not.

  • Dynamic uses reflection internally. It caches the method calls made thus improving performance to a certain extent.

  • Reflection can invoke both public and private members of an object while dynamic can only invoke public members.
