Casting to an Interface in c sharp

http://dotnetpoint.blogspot.com/ 2008/ 05/ casting-to...

You can access the members (i.e., methods and properties) of an interface through the object of any class that implements the interface. Thus, you can access the methods and properties of IStorable, through the Document object: Document doc = new Document("Test Document"); doc.status = -1; doc.Read(); When you cast you say to the compiler, "trust me, I know this object is really of this type." In this case you are saying "trust me, I know this document really implements IStorable, so you can treat it as an IStorable." Casting is safe to do because the Document object implements IStorable and thus is safely treated as an IStorable object.
