如何将c++中的make_pair转换为c#

本文关键字：pair 转换 make c++ 中的 | 更新日期: 2023-09-27 18:11:23

map <pair<unsigned int, unsigned int>, unsigned int> kmapValues;


private Dictionary<KeyValuePair<uint, uint>, uint> kmapValues;
代替

kmapValues[make_pair(j, i)] = 1 


kmapValues[Tuple(j, i)] = 1 // got error

系统。元组是类型，但像变量一样使用错误

如何将c++中的make_pair转换为c#

您正在声明使用KeyValuePair<K,V>键的字典，但您试图使用Tuple<T1,T2>来访问它。你需要决定一种类型，并坚持下去。

由于KeyValuePair<K,V>是不对称的，我将使用Tuple<T1,T2>:

private Dictionary<Tuple<uint, uint>, uint> kmapValues;

那么你的分配就可以正常工作了:

kmapValues[Tuple.Create(j, i)] = 1;

//作为c#的扩展方法，在一些静态类上:

public static KeyValuePair<K, V> MakePair<K, V>(this K k, V v) { return new KeyValuePair<K, V>(k, v); }

我的解决方案是使用一个向量来重构，然后在c#接口附近映射，然后包装器函数通过引用返回子元素，然后可以根据需要重新组合;这有点麻烦，但我认为值得。

最近一个项目的例子:如您所见，这里有很多函数调用，但仍然相当简单。
