[RESOLVED] Help optimising LINQ query is needed

I've a class

Code:

---

Class DeclInfo
{
    public int Year {get; set;}
    public int Quarter {get; set;}
    public int CorrectionNumber {get; set;}
    // ...
} // class DeclInfo

---

I'm writing a method FindFirst which queries a collection of DeclInfo to find an earliest instance:
Find earliest year, then find earliest quarter and then find the latest (max) correction number.

Now I have the following:

Code:

---

int Criteria = allDecls.Min(d => d.Year);
allDecls = allDecls.Where(d => d.Year == Criteria).ToList();
Criteria = allDecls.Min(d => d.Quarter);
allDecls = allDecls.Where(d => d.Quarter == Criteria).ToList();
Criteria = allDecls.Max(d => d.CorrectionNumber);
di = allDecls.First(d => d.CorrectionNumber == Criteria);

---

I don't like what I see very much and therefore - a question - is there a way to make it simpler?

Here's an alternative using OrderBy and ThenBy().

Code:

---

DeclInfo info = new DeclInfo();
            info = declinfosDummy
                .OrderBy(t => t.Year)
                .ThenBy(t => t.Quarter)
                .ThenByDescending(t => t.CorrectionNumber)
                .ToList().First();

I tested the output produced by your LINQ statements against my LINQ statement. The results were identical.
