比较两个字典并返回另一个字典中的差异 [英] Comparing two dictionaries and returning the differences in another dictionary

问题描述

我有两个字典，我想比较两个字典的键/对值.当我比较它们时，如果第二个字典中的值不同，我想保持它们的配对并将其存储到字典 3 中.

I have two dictionaries and I wish to compare the two dictionaries key / pair values. When I compare them if the value is different in the second dictionary I want to keep their pairing and store that into dictionary3.

所以如果我有字典 1 和 (<1,T><2,T><3,T>) 和 2 (<1,T>)<2,F><3,T>) 我希望 3 看起来像 (<2,F>).

So if I have dictionary 1 with (<1,T><2,T><3,T>) and 2 with (<1,T><2,F><3,T>) I want 3 to look like (<2,F>).

我不知道从哪里开始这个.我有字典正确获取所有数据，但现在我不确定如何设置比较.

I am not sure where to start with this one. I have the dictionaries properly getting all their data but right now I am not sure how to set up the compare.

private Dictionary<int, bool> CompareDictionaries(Dictionary<int, bool> dic2)
{
    Dictionary<int,bool> dictionary3 = new Dictionary<int,bool>();

    foreach (KeyValuePair<int, bool> pair in dictionary1)
    {
        // keep KeyValuePair of dic2
        // dictionary3.add(KeyValuePair of dic 2)
    }

    return dictionary3;
}

对此的任何帮助将不胜感激.我很肯定我可以用字典实现我的目标.在我获得第三本字典后，我将更新表格中的一些信息，然后刷新我正在显示的列表，但该部分要容易得多，然后找出我需要的方法和算法.任何帮助一如既往地非常感谢.谢谢各位.

Any help on this would be appreciated. I am pretty positive that I can accomplish my goal with dictionaries. Down the line after I get the 3rd dictionary I am going to update some information in a table and then refresh a list I am displaying but that part is much easier then figure out what methods and algorithm I need for this part. Any help is as always very very appreciated. Thank guys.

推荐答案

var dict3 = dict2.Except(dict1).ToDictionary(x => x.Key, x => x.Value);
