Sort list by field (C#)

Question

I have class like:

class SortNode
{
    public Int32 m_valRating = 0;

    public SortNode(Int32 valRating)
    {
        this.m_valRating = valRating;
    }         


        

Answer 1

List refSortNodeList = new List ();

Random refRandom = new Random ();

for (int i = 0; i < 100; ++i) {
    refSortNodeList.Add (new SortNode (refRandom.Next (-10, 30)));
}

// Use this (Linq) if you're using .NET 3.5 or above.
var sortedList = refSortNodeList.OrderBy (node => node.m_valRating);
foreach (var varSortNode in sortedList) {
    Console.WriteLine ("SortNode rating is {0}", varSortNode.m_valRating);
}

// Use this otherwise (e.g. .NET 2.0)
refSortNodeList.Sort (
    delegate (SortNode n1, SortNode n2) {
        return n1.m_valRating.CompareTo (n2.m_valRating);
    }
);

foreach (var varSortNode in refSortNodeList) {
    Console.WriteLine ("SortNode rating is {0}", varSortNode.m_valRating);
}
