Check if a List already contains an item or not?

I used a struct

public struct stuff
{
    public int ID;
    public int quan;
}

in List<stuff> stuff = new List<stuff>();

How i can check the list already have a stuff "where ID = 1"?

You can use LINQ very easily

bool res = stuff.Any(c => c.ID == 1);

if(stuf.Select(x => x.id).Contains(1))
{
    //Do Stuff
}
