Following code does always fails even when they contain the same. Reason is that they are of two different type(string and ListViewItem). How do I fix it ?

// nostr is a string
foreach (ListViewItem item in listView1.Items)
{
if (item(nostr))
item.SubItems[4].Text = "Equal";
}
 
id do something along these lines ...
C#: 
				foreach(ListViewItem lvi in listView1.Items)
				{
					foreach(ListViewItem.ListViewSubItem lvs in lvi.SubItems)
					{
						if(lvs.Text=="equals")
						{
							Console.WriteLine(lvs.Text + " was found at index:" + lvi.SubItems.IndexOf(lvs).ToString());
						}
					}
				}
 
Is it really necessary to run through all list items and sub items to see if a subitem is equal a textstring ?

What is giving the problem is when I try to compare an item from Listview with a string. !!!

if (item(nostr)) should have been replaced with
if (item.Equals(nostr)). Sorry.
 
without looping the subitems seperatly , you can do this ...
C#: 
				foreach(ListViewItem lvi in listView1.Items)
				{
					if(lvi.SubItems.Count > 4) /// make sure we have enough subitems
					{
						ListViewItem.ListViewSubItem lvs = (ListViewItem.ListViewSubItem)lvi.SubItems[4];
						if(lvs.Text == "equals")
						{
							MessageBox.Show(lvs.Text);
						}
					}
				}
