Question

How do I do this in linq?

var p = new pmaker();   foreach (var item in itemlist)  {    var dlist = new List<Dummy>();    foreach (var example in item.examples)    {       dlist.Add(example.GetDummy());     }    p.AddStuff(item.X,item.Y,dlist);  }  // .. do stuff with p

How about:

var qry = from item in itemlist           select new {item.X, item.Y,               Dummies = item.examples.Select(                 ex => ex.GetDummy())           }; foreach (var item in qry) {     p.AddStuff(item.X, item.Y, item.Dummies.ToList()); } 

Not sure it is much clearer like this, though… personally I think I might just use the original foreach version… maybe splitting out the GetDummy bit:

foreach (var item in itemlist) {     var dlist = item.examples.Select(ex => ex.GetDummy()).ToList();     p.AddStuff(item.X,item.Y,dlist); }
