Question

I have following var result = new List<Tuple<int, List<ProductionReportEntry>, int>>();

How I can sort it by the last integer , that the result will be from high to Low .

Thanks for help.

The easiest way is to use LINQ’s OrderByDescending() extension method, it will sort your list in descending order from high to low and push it back into the list:

result = result.OrderByDescending(t => t.Item3).ToList();

That’s assuming you want to store it back int the original reference, of course you could assign it to another variable, etc…

Alternatively, you could do an in-place sort using List.Sort()‘s overload that takes a Comparisson<T> delegate:

// does descending since we put r on the lhs and l on the rhs...
result.Sort((l, r) => r.Item3.CompareTo(l.Item3));

Alternatively, you could build a custom IComparer<T>, of course for your Tuple<int, List<PropertyReportEntry>, int> but that gets pretty ugly looking…
