C# Break out of foreach loop after X number of items

int processed = 0;
foreach(ListViewItem lvi in listView.Items)
{
   //do stuff
   if (++processed == 50) break;
}

or use LINQ

foreach( ListViewItem lvi in listView.Items.Cast<ListViewItem>().Take(50))
{
    //do stuff
}

or just use a regular for loop (as suggested by @sgriffinusa and @Eric J.)

for(int i = 0; i < 50 && i < listView.Items.Count; i++)
{
    ListViewItem lvi = listView.Items[i];
}
