如何从字典继承？ [英] How do I inherit from Dictionary?

问题描述

我希望所有的的功能字典< TKEY的，TValue> ，但我想它作为美孚< TKEY的，TValue> 。


我应该如何去这样做呢？

目前我使用

I want all the functionality of Dictionary<TKey,TValue> but I want it as Foo<TKey,TValue>.
How should I go about doing this?
Currently I am using

class Foo<TKey,TValue> : Dictionary<TKey, TValue>
{   
    /*
     I'm getting all sorts of errors because I don't know how to 
     overload the constructors of the parent class.
    */
    // overloaded methods and constructors goes here.

    Foo<TKey,TValue>():base(){}
    Foo<TKey,TValue>(int capacity):base(capacity){}

}

什么是过载构造函数和父类方法的正确方法？

注：我想我已经滥用词'超载'，请更正或建议修正的

NOTE:I think I have misused the word 'overload' please correct it or suggest correction.

推荐答案

您很接近，你只需要在构造函数中删除类型参数。

You were close, you just need to remove the type parameters from the constructors.

class Foo<TKey,TValue> : Dictionary<TKey, TValue>
{   
    Foo():base(){}
    Foo(int capacity):base(capacity){}
}

要覆盖您可以使用override关键字的方法。

To override a method you can use the override keyword.
