Tuple<int, int> Compare operator

Question

Hello,

if I compare two tuples always is null, why?

//What am I doing wrong?
//I have two tuples and want to compare for equality.
//Is always zero, only when I go through the list, it matches.


public Tuple<int, int> Id { get; set; }


protected readonly Tuple<int, int> m_id;
public Tuple<int, int> Id { get { return m_id; } }  



var ret = ListID.FirstOrDefault(x => x.Id == conv.Id);
ret = ListID.Where(x => x.Id == conv.Id).FirstOrDefault();

foreach (var item in ListID)
{
    if (item.Id.Item1 == conv.Id.Item1 && item.Id.Item2 == conv.Id.Item2)
    {
        ret = item;
        break;
    }
}

if (ret != null)

Thanks for tips in advance.

Try this:

var ret = ListID.FirstOrDefault(x => x.Id.Equals(conv.Id));
