如何使用复合键的字典？ [英] How to use compound key for dictionary?

问题描述

我需要安排排序词典，其中的关键是一对枚举和INT的 和值对象。所以，我要地图一对一些对象。

I need to arrange sort of dictionary where the key would be a pair of enum and int and value is object. So I want to map a pair to some object.

一种选择是

public enum SomeEnum
{
 value1, value2
}

class Key
{
  public SomeEnum;
  public int counter;  

  // Do I have to implement Compare here?
}

Dictionary<SomeEnum, object> _myDictionary;

另一种办法是转换枚举和int到一些独特的密钥。

Another option would convert enum and int to some unique key.

string key = String.Format("{0}/{1}", enumValue, intValue)

这方法要求字符串解析，很多额外的工作。

That approach requires string parsing, a lot of extra work.

如何使它容易吗？

推荐答案

我会用类似的东西去

public enum SomeEnum
{
 value1, value2
}

public struct Key
{
  public SomeEnum;
  public int counter;  
}

Dictionary<Key, object>

我认为这将使它？

I think that would make it?
