This means that the derived class can provide its own implementation for an attribute that is also defined in the parent class. This can be useful if the derived class needs to change the behavior of the attribute or if it needs to provide a different implementation for the attribute for different types of objects.<\/p>\n<p>For example, consider the following code:<\/p>\n<p>&#8220;`class Animal {<br \/>\n  public string name;<br \/>\n  public void Speak() {<br <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n            <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div>     <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> \/>\n    Console.WriteLine(&#8220;I am an animal&#8221;);<br \/>\n  }<br \/>\n}<\/p>\n<p>class Dog : Animal {<br \/>\n  public override string name {<br \/>\n    get { return &#8220;Spot&#8221;; }<br \/>\n  }<\/p>\n<p>public override void Speak() {<br \/>\n    Console.WriteLine(&#8220;Woof!&#8221;);<br \/>\n  }<br \/>\n}<br \/>\n&#8220;`<\/p>\n<p>In this code, the <code>Dog<\/code> class overrides the <code>name<\/code> and <code>Speak<\/code> attributes of the <code>Animal<\/code> class.

If you override an attribute in a derived class, you should make sure that your implementation is compatible with the implementation in the parent class.
