In C#, “override” is a modifier for a method that indicates that the derived class is rewriting (or overriding) a method with the same name in the base class. “Override” has the following characteristics:<\/p>\n

    \n
  1. The method must have the same name, parameter list, and return type as the virtual or abstract method in the base class.<\/li>\n
  2. The “override” keyword can only be used in derived classes and not in base classes or non-derived classes.<\/li>\n
  3. The overridden method must be declared as a virtual method (using the keyword virtual) or an abstract method (using the keyword abstract) in the base class.<\/li>\n
  4. The “override” keyword can be used to override virtual properties (using the “virtual” keyword) or abstract properties (using the “abstract” keyword) in a base class.<\/li>\n
  5. The overridden method can call the implementation in the base class using the base keyword.<\/li>\n
  6. The keyword “override” can be used to rewrite the ToString() and Equals() methods in the base class in order to customize the string representation and comparison logic of a custom class.<\/li>\n
  7. The overwritten method can have increased access modifiers, but cannot change the return type.<\/li>\n
  8. Overriding methods can throw exceptions, but they cannot throw more exceptions than the base class method.<\/li>\n
  9. The “override” keyword can be used with the “sealed” keyword to indicate that further derived classes are prohibited from overriding that method.<\/li>\n<\/ol>\n

    These characteristics make the “override” keyword an important mechanism for achieving polymorphism in C#, allowing derived classes to replace methods in the base class with their own implementation, providing more flexible and specific behavior.<\/p>\n","protected":false},"excerpt":{"rendered":"
