c# - Sort Only One Element Of KeyValuePair inside List<t> -


i have following implementation

public static list<keyvaluepair<int, double>> entries = new list<keyvaluepair<int, double>>(); entries.add(new keyvaluepair<int, double>(j, min));

for mathematical computation, want sort min value , not j key. how can done? thanks.

edit: using class level variables , tried repeatedly 

psolib.entries = psolib.entries.orderby(kvp => kvp.value).tolist(); linechart.datacontext = psolib.entries;

and values simple don't sorted. did screw?

entries = entries.orderby(kvp => kvp.value).tolist();

c# - How do I get the Nth largest element from a list with duplicates, using LINQ? -

i've seen in various stackoverflow answers can nth largest element in list doing var nthfromtop = items.orderbydescending().skip(n-1).first(); but wouldn't work if there no duplicates in list? if list contains duplicates, there way nth largest element (or set of elements) using linq? if not, efficient way in c#? to set of items equal nth largest item you'll need group items, order groups, , decrement n group size while n positive. when n reaches zero, you've hit group containing nth largest item. public static ienumerable<t> foo<t>(this ienumerable<t> source, int n) { return source.groupby(x => x) .orderbydescending(group => group.key) .skipwhile(group => { n -= group.count(); return n > 0; }) .first(); }
