They are not comparable, but may have some relationship between them.
An abstract class is a class, while a virtual function (or method) is a method. A method must exist within a class. Hence, a class has methods, and the methods may be defined as virtual functions.
A virtual function must be defined in a class, but that class does not have to be an abstract class. However, the purpose of a virtual function in C# is to provide a default behavior/implementation, while allowing the derived class to override that default implementation, hence it makes no sense to define a virtual function in a sealed class (a leaf, that is, no class can extend from it, and it is not an abstract class)
Example:
public class Parent {
public virtual string MostCommonPhrase() {
return "You better listen to me...";
}
}
public class Child : Parent {
public override string MostCommonPhrase() {
return "You never listen to me...";
}
}
This is like a tamplate. You make this kind of class and than later you can override it and put it to use.
The difference between the Class 365 and Class 465, 466 is basically the cost.
