Simple, try the following codes as examples :

Foreach example 1 : 

foreach(ListViewItem lvi in listView.Items.Skip(20))
{
   //faça algo
   if (++itens == 50) break;
}

Foreach example 2 : 

foreach(var itens in dicionario.Items.Skip(20).Take(50))

For : 

for(int itens = 20; i <= 50 && i < dicionario.Items.Count; i++)
{
    ListViewItem lvi = dicionario.Items[i];
}

LINQ : 

foreach( ListViewItem lvi in dicionario.Items.Cast<ListViewItem>().Skip(20).Take(50))
{
    //faça algo
}

For further clarification, take a look at the documentation of foreach here and of for here.

And for a better understanding of the methods Skip() and Take() take a look here.
