Question

如何比较两个词典，我的词典如下

  Dictionary<string, string> dic = new Dictionary<string, string>();
  dic.Add("One", "One");
  dic.Add("Two", "Two");

  Dictionary<string, string> dic1 = new Dictionary<string, string>();
  dic1 .Add("One", "One");
  dic1 .Add("Two", "Two");
  dic1 .Add("Three", "Three");

我尝试了一些像var diff = dic1.Where(x => x.Value != dic[x.Key]).ToDictionary(x => x.Key, x => x.Value);这样的东西，但我得到了异常，因为密钥不匹配所以有人可以帮助我

Answer 1

这会给你带来不同，

var resultDic = dic1.Except(dic).ToDictionary(x => x.Key, x => x.Value);

Answer 2

    private void Comparer(Dictionary<string, string> dic, Dictionary<string, string> dic1)
    {
        var diff = dic.Except(dic1).Concat(dic1.Except(dic));
    }

比较两个词典并将结果存储在其他词典中
