Difference between these two casts
c#, class, interface, object
Solution
The first one is indeed an implicit cast. To cite Microsoft:
For reference types, an implicit conversion always exists from a class to any one of its direct or indirect base classes or interfaces. No special syntax is necessary because a derived class always contains all the members of a base class.
The second cast is an explicit conversion, and as already mentioned is not necessary for the reason stated above. Explicit conversions are necessary when some of the information could/would get lost during the casting and tells the compiler how to handle that.
Microsoft has a nice article about casting: http://msdn.microsoft.com/en-us/library/ms173105.aspx
Problem
I'm really not fully familiar with casting. So feel free to edit or comment changes to my question. Let's say I have a class that implements an interface: ``` public class Class1: Interface1 { } ``` Whats the difference between these two?: ``` Interface1 myObject = new Class1(); ``` and ``` Class1 myClassObject = new Class1(); Interface1 myObject = (Interface1) myClassObject; ``` Is the first one also a form of casting? Edit: What does each one do?
