In C#, method overriding and hiding are achieved through inheritance and access modifiers.<\/p>\n

    \n
  1. Override method: When a subclass rewrites a method of the parent class, the “override” keyword can be used. The overridden method must have the same name, parameter list, and return type as the parent class method. For example:<\/li>\n<\/ol>\n
    class<\/span> BaseClass<\/span>\r\n{\r\n    public<\/span> virtual<\/span> void<\/span> Print<\/span>()<\/span>\r\n    {\r\n        Console.WriteLine(\"Base Class\"<\/span>);\r\n    }\r\n}\r\n\r\nclass<\/span> DerivedClass<\/span> : BaseClass<\/span>\r\n{\r\n    public<\/span> override<\/span> void<\/span> Print<\/span>()<\/span>\r\n    {\r\n        Console.WriteLine(\"Derived Class\"<\/span>);\r\n    }\r\n}\r\n\r\nBaseClass baseObj = new<\/span> DerivedClass(); \/\/ \u521b\u5efa\u5b50\u7c7b\u5bf9\u8c61\uff0c\u8c03\u7528\u5b50\u7c7b\u7684Print\u65b9\u6cd5<\/span>\r\nbaseObj.Print(); \/\/ \u8f93\u51fa\uff1a\"Derived Class\"<\/span>\r\n<\/code><\/pre>\n
      \n
    1. Method hiding: In a subclass, hiding a method from the parent class can be done using the ‘new’ keyword. The hidden method does not need to have the same name, parameter list, or return type as the parent class method, but it is recommended for clarity to keep them consistent to avoid confusion. An example is shown below:<\/li>\n<\/ol>\n
      class<\/span> BaseClass<\/span>\r\n{\r\n    public<\/span> void<\/span> Print<\/span>()<\/span>\r\n    {\r\n        Console.WriteLine(\"Base Class\"<\/span>);\r\n    }\r\n}\r\n\r\nclass<\/span> DerivedClass<\/span> : BaseClass<\/span>\r\n{\r\n    public<\/span> new<\/span> void<\/span> Print<\/span>()<\/span>\r\n    {\r\n        Console.WriteLine(\"Derived Class\"<\/span>);\r\n    }\r\n}\r\n\r\nBaseClass baseObj = new<\/span> DerivedClass(); \/\/ \u521b\u5efa\u5b50\u7c7b\u5bf9\u8c61\uff0c\u8c03\u7528\u7236\u7c7b\u7684Print\u65b9\u6cd5<\/span>\r\nbaseObj.Print(); \/\/ \u8f93\u51fa\uff1a\"Base Class\"<\/span>\r\n<\/code><\/pre>\n
      Through these two methods, it is possible to achieve method overriding and hiding, allowing subclasses to customize the processing of parent class methods.<\/p>\n","protected":false},"excerpt":{"rendered":"
