推荐答案

您的问题不是很清楚.

如果我对您的理解正确，则可以从内置类继承您自己的类，然后使用例如new关键字覆盖方法.

但是，您不能使用此技术用不同于原始参数的其他一些参数替换方法，您可以替换"原始实现.有关更多信息，请参见: http://msdn.microsoft.com/zh-cn/library/51y09td4(v = vs.71).aspx#vclrfnew_newmodifier [扩展方法 [

Your question isn''t very clear.

If I understood you correctly, you can inherit your own class from the built in class and then use for example new keyword to override a method.

However, you cannot use this technique to replace a method with some other parameters that are different than original parameters, you can just ''replace'' the original implementation. For more info see: http://msdn.microsoft.com/en-us/library/51y09td4(v=vs.71).aspx#vclrfnew_newmodifier[^].

You can add new methods for inherited classes that are not included in the original class and you can also use extension methods[^] to add functionality to a builtin class without having to derive a new class from it if that''s what you''re after.
