Starting with the .NET Framework 4.5, the TypeInfo class is included in the .NET for Windows Store apps subset for use in creating Windows Store apps. TypeInfo is available in the full .NET Framework as well. For more information about reflection for Windows Store apps, see System.Reflection namespaces in the Windows Dev Center and Reflection in the .NET Framework for Windows Store Apps in the MSDN Library.

TypeInfo contains many of the members available in the Type class, and many of the reflection properties in the .NET for Windows Store apps return collections of TypeInfo objects. To get a TypeInfo object from a Type object, use the GetTypeInfo method.

A TypeInfo object represents the type definition itself, whereas a Type object represents a reference to the type definition. Getting a TypeInfo object forces the assembly that contains that type to load. In comparison, you can manipulate Type objects without necessarily requiring the runtime to load the assembly they reference.

In the .NET for Windows Store apps, you use the reflection properties of TypeInfo that return IEnumerable(Of T) collections instead of methods that return arrays. For example, use the DeclaredMembers property to get all declared members, or the DeclaredProperties property to get all declared properties. Reflection contexts can implement lazy traversal of these collections for large assemblies or types. To get specific members, use methods such as GetDeclaredMethod and GetDeclaredProperty, and pass the name of the method or property you would like to retrieve.

To filter the results of TypeInfo properties, use LINQ queries. For reflection objects that originate with the runtime (for example, as the result of typeof(Object)), you can traverse the inheritance tree by using the methods in the RuntimeReflectionExtensions class. Consumers of objects from customized reflection contexts cannot use these methods and must traverse the inheritance tree themselves.

This example uses the reflection types and members in the .NET for Windows Store apps subset to retrieve the methods and properties of the Calendar type, including inherited methods and properties. To run this code, paste it into the code file for a Windows Store XAML app that contains a Windows.UI.Xaml.Controls.Textblock control named textblock1.
