C#加入字典，并提供其他信息

我加入简单字典没有问题，这段代码很好：

        Dictionary<string, int> lala01 = new Dictionary<string, int>();
        lala01.Add("A", 5);
        lala01.Add("B", 2);
        lala01.Add("C", 8);

        Dictionary<string, int> lala02 = new Dictionary<string, int>();
        lala02.Add("A", 1);
        lala02.Add("B", 9);
        lala02.Add("X", 4);

        Dictionary<string, int> lala03 = new Dictionary<string, int>();
        lala03.Add("A", 7);
        lala03.Add("C", 4);
        lala03.Add("X", 1);
        lala03.Add("Q", 2);

        List<Dictionary<string, int>> dictionaries = new List<Dictionary<string, int>>();
        dictionaries.Add(lala01);
        dictionaries.Add(lala02);
        dictionaries.Add(lala03);

        var result = dictionaries.SelectMany(dict => dict)
                     .ToLookup(pair => pair.Key, pair => pair.Value)
                     .ToDictionary(group => group.Key, group => group.Max());

我应该编写什么代码来只包含具有最大整数的keyvaluepair？

如果您只需要max by value对，您可能正在寻找类似MaxBy（从）的东西

如果不能使用更多linq，可以先使用

命令执行
OrderBy

 var result = dictionaries.SelectMany(dict => dict)
              .ToLookup(pair => pair.Key, pair => pair.Value)
              .ToDictionary(group => group.Key, group => group.OrderByDescending(v=> v.Key).First());

如果按键排序，则这是答案！非常感谢。
        var result = dictionaries.SelectMany(dict => dict)
                     .ToLookup(pair => pair.Key, pair => pair.Value);
                     //Basically I am clueless here  .ToDictionary(group => group.Key, group => group.Select(x => x).Max(x => x.Key)); 

 var result = dictionaries.SelectMany(dict => dict)
              .ToLookup(pair => pair.Key, pair => pair.Value)
              .ToDictionary(group => group.Key, group => group.MaxBy(v=> v.Key));

 var result = dictionaries.SelectMany(dict => dict)
              .ToLookup(pair => pair.Key, pair => pair.Value)
              .ToDictionary(group => group.Key, group => group.OrderByDescending(v=> v.Key).First());
