Remarks
ConstructorBuilder is used to fully describe a constructor in Microsoft intermediate language (MSIL), including the name, attributes, signature, and constructor body. It is used in conjunction with the TypeBuilder class to create classes at run time. Call DefineConstructor to get an instance of ConstructorBuilder.
If you do not define a constructor for your dynamic type, a default constructor is provided automatically, and it calls the default constructor of the base class.
If you use ConstructorBuilder to define a constructor for your dynamic type, a default constructor is not provided. You have the following options for providing a default constructor in addition to the constructor you defined:
If you want a default constructor that simply calls the default constructor of the base class, you can use the TypeBuilder.DefineDefaultConstructor method to create one (and optionally restrict access to it). Do not provide an implementation for this default constructor. If you do, an exception is thrown when you try to use the constructor. No exception is thrown when the TypeBuilder.CreateType method is called.
If you want a default constructor that does something more than simply calling the default constructor of the base class, or that calls another constructor of the base class, or that does something else entirely, you must use the TypeBuilder.DefineConstructor method to create a ConstructorBuilder, and provide your own implementation.
