自定义类用作字典中的键，但未找到键

问题描述

我有一个类，在下面显示，它被用作字典< ValuesAandB，string>
中的一个键。在这本字典中找到任何键，它根本找不到。如您所见，我已经覆盖了等于和 GetHashCode 。

I have a class, show below, which is used as a key in a Dictionary<ValuesAandB, string>I'm having issues when trying to find any key within this dictionary, it never finds it at all. As you can see, I have overridden Equals and GetHashCode.

要查找我正在使用的密钥

To look for the key I'm using

ValuesAandB key = new ValuesAandB(A,B);
if (DictionaryName.ContainsKey(key)) {
   ...
}

还有什么我失踪的吗？任何人都可以指出我在做错什么？

Is there anything else that I'm missing? Can anyone point out what I'm doing wrong?

private class ValuesAandB {
   public string valueA;
   public string valueB;

   // Constructor
   public ValuesAandB (string valueAIn, string valueBIn) {
     valueA = valueAIn;
     valueB = ValueBIn;
   }

   public class EqualityComparer : IEqualityComparer<ValuesAandB> {
      public bool Equals(ValuesAandB x, ValuesAandB y) {
         return ((x.valueA.Equals(y.valueA)) && (x.valueB.Equals(y.valueB)));
      }
      public int GetHashCode(ValuesAandB x) {
         return x.valueA.GetHashCode() ^ x.valueB.GetHashCode();
      }
   }
}

在任何人要求之前，是这些值在字典中！

And before anyone asks, yes the values are in the Dictionary!

推荐答案

你如何构建字典？您是否将自定义的平等比较器传递给其构造函数？

How are you constructing the dictionary? Are you passing your custom equality comparer in to its constructor?
