Get single listView SelectedItem

If its just a natty little app with one or two ListViews I normally just create a little helper property:

private ListViewItem SelectedItem { get { return (listView1.SelectedItems.Count > 0 ? listView1.SelectedItems[0] : null); } }

If I have loads, then move it out to a helper class:

internal static class ListViewEx
{
    internal static ListViewItem GetSelectedItem(this ListView listView1)
    {
        return (listView1.SelectedItems.Count > 0 ? listView1.SelectedItems[0] : null);
    }
}

so:

ListViewItem item = lstFixtures.GetSelectedItem();

The ListView interface is a bit rubbish so I normally find the helper class grows quite quickly.

Usually SelectedItems returns either a collection, an array or an IQueryable.

Either way you can access items via the index as with an array:

String text = listView1.SelectedItems[0].Text; 

By the way, you can save an item you want to look at into a variable, and check its structure in the locals after setting a breakpoint.

I do this like that:

if (listView1.SelectedItems.Count > 0)
{
     var item = listView1.SelectedItems[0];
     //rest of your logic
}

Sometimes using only the line below throws me an Exception,

String text = listView1.SelectedItems[0].Text; 

so I use this code below:

private void listView1_SelectedIndexChanged(object sender, EventArgs e) 
{ 
    if (listView1.SelectedIndices.Count <= 0) 
    { 
        return; 
    } 
    int intselectedindex = listView1.SelectedIndices[0]; 
    if (intselectedindex >= 0) 
    {
        String text = listView1.Items[intselectedindex].Text;

        //do something
        //MessageBox.Show(listView1.Items[intselectedindex].Text); 
    } 
}
