While the object can subsequently be cast to various types, it can never change its runtime type — many aspects of type systems and features (such as virtual dispatch) depend on this.</p> <p>In this post, we will see how we can use unsafe code in C# to bypass the type system and change a .NET object&rsquo;s runtime type. Then, we will see an unusual case where it would be neat to have this. Needless to say, don&rsquo;t try this in real code.</p>
