Overriding the default reflection behavior


One interesting capability of .NET 4.5 is that we can customize our reflection context, overriding the default reflection behavior with the CustomReflectionContext class.

With it, we can control what properties and attributes are exposed by a class through reflection.

How to do it...

Here we will override the reflection behavior to provide additional attributes:

  1. Create a new Visual Studio project of type Console Application named caOverridingReflection.

  2. In the References folder of the project, in the Solution Explorer, add a reference to the System.Reflection.Context assembly.

  3. Open the Program.cs file and add a using clause for system.reflection.

    using System.Reflection;
  4. Next, add the SomeClass declaration:

    class SomeClass
    {
        //Nothing here..
    }
  5. Then add a method to visualize, through reflection, the attributes of a type:

    public static void ShowAttributes(Type t)
    {
      foreach (Attribute a in t.GetCustomAttributes())
        {
          Console.WriteLine(a);
      ...
