TypeBuilder

System.Reflection.Emit (mscorlib.dll)

sealed class

This class represents a dynamically created type in a dynamic module ( ModuleBuilder object). Generally, a type is either a class or an interface. To create a TypeBuilder , use the overloaded ModuleBuilder.DefineType( ) method. Depending on which overload you use, you can specify different information including the type name , superclass, and implemented interfaces. You can also use the System.Reflection.TypeAttributes enumeration to specify other options, such as making a class sealed, abstract, or public, or defining it as an interface. Once the type is created, you can add members such as constructors, events, fields, properties, methods , and other nested types, using the corresponding Define method.

Before using a type you created, you must use the CreateType( ) method to get a Type object. After that, you can instantiate the Type with the System.Activator.CreateInstance( ) method, and invoke members of the type with the System.Type.InvokeMember( ) method. After creating a type, you can no longer use TypeBuilder methods that would change the type, such as a Define method.
