What’s Dynamic Keyword Insertion, And How Should I Use It?

Whats the use of virtual keyword in c#?

• e.g: public virtual void ClearLastException() { LastException = null; }

• Answer:

  When you create a child class of the class which contains the virtual method you will be able to override the method which has the virtual keyword. in your example you have a method 'clearLastException'. If i was to create a class which is a child class of the parent class which contains 'clearLastException' i would be able to override this method. msdn explanation: http://msdn2.microsoft.com/en-us/library/9fkccyh4.aspx wikipaedia explanation of inheritance: http://en.wikipedia.org/wiki/Inheritance_%28computer_science%29
