Walkthrough: Creating and Using Dynamic Objects (C# and Visual Basic). 11 minutes to read. Contributors. In this article Dynamic objects expose members such as properties and methods at run time, instead of in at compile time. This enables you to create objects to work with structures that do not match a static type or format.

Because each HTML document is unique, the members for a particular HTML document are determined at run time. A common method to reference an attribute of an HTML element is to pass the name of the attribute to the GetProperty method of the element. To reference the id attribute of the HTML element, you first obtain a reference to the element, and then use divElement.GetProperty('id'). If you use a dynamic object, you can reference the id attribute as divElement.id. Dynamic objects also provide convenient access to dynamic languages such as IronPython and IronRuby. You can use a dynamic object to refer to a dynamic script that is interpreted at run time.

You reference a dynamic object by using late binding. In C#, you specify the type of a late-bound object as dynamic. In Visual Basic, you specify the type of a late-bound object as Object. For more information, see and. You can create custom dynamic objects by using the classes in the namespace.
For example, you can create an and specify the members of that object at run time. You can also create your own type that inherits the class. You can then override the members of the class to provide run-time dynamic functionality. In this walkthrough you will perform the following tasks:. Create a custom object that dynamically exposes the contents of a text file as properties of an object. Create a project that uses an IronPython library.
