Can we update a list using anonymous methods?

Question

I have a list (MyList) of objects...and I would like to update one property (Priority) of each item in that list.

Will the below code work for that ?

this.MyList.All(
    delegate(ItemViewModel itemObject)
    {   
        itemObject.Priority = priority++;
    }
)

Please help me. Thanks in advance!

Answer 1

Why not just use foreach?

foreach(ItemViewModel itemObject in MyList)
  itemObject.Priority = priority++;

If you really want to use a delegate you can use ForEach():

MyList.ForEach(itemObject =>
{
    itemObject.Priority = priority++;
});

This is not advisable though since you introduce a side effect with priority++
