C #=& amp; gt; virtual Method

1. If the keyword is virtual, a base class function can be declared as a virtual method. Public virtualvoid myVirtualMethod (){}

2. You can also declare the attribute as virtual.

Public virtual int iCount {get; set ;}

3. The virtual function can be rewritten in a derived class. Use the keyword override.

4. All functions in java are virtual, but C # is different. Except constructors, functions in C # Are not virtual by default, in addition, C # requires that the override keyword must be used to display the declaration when the function of the derived class is rewritten.

5. The advantage of override display Declaration is that C ++ ignores this problem if the method name of the derived class is slightly different from the base class, however, a compilation error occurs in C # because the function is marked as override.
