Name GetInterfaces GetMember GetMembers GetMethod GetMethods GetNestedType GetNestedTypes GetProperty GetProperties IsInstanceOfType IsSubclassOf Description Retrieves all the InterfaceInfo objects that are associated with this Type Retrieves a specific MemberInfo object that is associated with this Type Retrieves all the MemberInfo objects that are associated with this Type Retrieves a specific MethodInfo object that is associated with this Type Retrieves all the MethodInfo objects that are associated with this Type Retrieves a specific Type object that is nested within this Type Retrieves all the Type objects that are nested within this Type Retrieves a specific PropertyInfo object that is associated with this Type Retrieves all the PropertyInfo objects that are associated with this Type Tests an object to see whether it is an instance of this Type Tests to see whether this Type ultimately derives from a specific Type Once you get an instance of the Type object, you can use it to get information about the type, like so: ' VB Dim t as Type = GetType(String) Console.WriteLine("Type: {0}", t.Name) Console.WriteLine(" Namespace : {0}", t.Namespace) Console.WriteLine(" FullName : {0}", t.FullName) Lesson 3: Reflecting Types
Console.WriteLine(" Console.WriteLine(" Console.WriteLine(" Console.WriteLine(" Console.WriteLine(" Is Is Is Is Is
ValueType : Sealed : Abstract : Public : Class : {0}", {0}", {0}", {0}", {0}", t.IsValueType) t.IsSealed) t.IsAbstract) t.IsPublic) t.IsClass) // C# Type t = typeof(String); Console.WriteLine("Type: {0}", t.Name); Console.WriteLine(" Namespace : {0}", Console.WriteLine(" FullName : {0}", Console.WriteLine(" Is ValueType : {0}", Console.WriteLine(" Is Sealed : {0}", Console.WriteLine(" Is Abstract : {0}", Console.WriteLine(" Is Public : {0}", Console.WriteLine(" Is Class : {0}", t.Namespace); t.FullName); t.IsValueType); t.IsSealed); t.IsAbstract); t.IsPublic); t.IsClass); In addition, you can check for attributes of a class in a similar fashion to the way you check for attributes of an assembly: ' VB For Each attr As Attribute In t.GetCustomAttributes(false) Console.WriteLine(" {0}", attr.GetType.Name) Next // C# foreach (Attribute attr in t.GetCustomAttributes(false)) { Console.WriteLine(" {0}", attr.GetType().Name); } The big difference between attributes of types and attributes of assemblies is that the inherit Boolean parameter that was ignored in the Assembly class is not ignored here. Because you can add attributes to any class in a class hierarchy, the inherit parameter tells the reflection system whether to get attributes that are on this specific type or attributes of all types in the inheritance hierarchy. What Type Is that Object
Ultimately, every object derives from the Object class that is at the top of the hierarchy. The Object class supports a method called GetType. This method returns a Type object that refers to the actual Type of an object. For example, say you create an Animal class: ' VB Public Class Animal End Class
14
Reflection
// C# public class Animal { } Now you create two classes that derive from this new class: ' VB Public Class Dog Inherits Animal End Class Public Class Cat Inherits Animal End Class // C# public class Dog : Animal { } public class Cat : Animal { } You can then create three instances, one of each of these classes. However, store them all as Animals and then show the Type s name in the console window: ' VB Dim anAnimal As Animal = New Animal Dim dogAnimal As Animal = New Dog Dim catAnimal As Animal = New Cat Console.WriteLine("Typename for anAnimal is {0}", _ anAnimal.GetType.Name) Console.WriteLine("Typename for dogAnimal is {0}", _ dogAnimal.GetType.Name) Console.WriteLine("Typename for catAnimal is {0}", _ catAnimal.GetType.Name) // C# Animal anAnimal = new Animal(); Animal dogAnimal = new Dog(); Animal catAnimal = new Cat(); Console.WriteLine("Typename for anAnimal is {0}", anAnimal.GetType().Name); Console.WriteLine("Typename for dogAnimal is {0}", dogAnimal.GetType().Name); Console.WriteLine("Typename for catAnimal is {0}", catAnimal.GetType().Name);
