Getting the max value out of a tuple in a dictionary in C#

Question

I have a dictionary declared as following:

Dictionary<Tuple<long, long>, Tuple<double, long>> dict= new Dictionary<Tuple<long, long>, Tuple<double, long>>(); 

How do I get the max value of Item2 of all dictionary values?

Answer 1

您可以像下面这样简单地使用Max LINQ方法：

long max = dict.Values.Max(x => x.Item2);

Answer 2

You can use the Max method . Not entirely clear which one of these you're asking for:

var maxKey = dict.Max(x => x.Key.Item2);
var maxValue = dict.Max(x => x.Value.Item2);

var maxEither = Math.Max(dict.Max(x => x.Key.Item2), dict.Max(x => x.Value.Item2));
