List排序问题

[deknight]

假设：
public class test
{
int count;
int rank;
}

list<test>
如何根据count排序，并重新为rank赋值？？

[Poopaye]

先排序 list.Sort((a, b) => a.count.CompareTo(b.count)); 再赋值 for(……) item.Rank = i;

[csdnFUCKINGSUCKS]

List<model> list = new List<model>() { new model() { count = 9, rank = 10 }, new model() { count = 3, rank = 50 }, new model() { count = 12, rank = 30 } };

//根据count正序
var resultASC = list.OrderBy(l => l.count).ToList();
//根据count倒序
var resultDESC = list.OrderByDescending(l => l.count).ToList();
//给正序结果的rank赋值
resultASC.ForEach(i => { i.rank = Enumerable.Range(1, 500).OrderBy(t => Guid.NewGuid()).FirstOrDefault(); });
//给倒序结果的rank赋值
resultDESC.ForEach(i => { i.rank = Enumerable.Range(1, 500).OrderBy(t => Guid.NewGuid()).FirstOrDefault(); });

foreach (var item in resultASC)
{
    Console.WriteLine(item.count + "==>" + item.rank);
}

Console.WriteLine("---------");

foreach (var item in resultDESC)
{
    Console.WriteLine(item.count + "==>" + item.rank);
}

List<test> datas = ....; 
var res = datas.OrderBy(d=>d.count).ToList();
