Question

I have tried to remove specific items from a listview using the RemoveAt() method. But When I remove it the first time some items will stay.

For example: see the image below

Code:

private void button1_Click(object sender, EventArgs e)
    {
        for (int i = 0; i < listView1.Items.Count; i++) 
        {
            if (listView1.Items[i].SubItems[0].Text == "A1") 
            {
                listView1.Items.RemoveAt(i);
            }
        }
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        for(int i = 0; i<3; i++)
        {
            ListViewItem lvi = new ListViewItem("A1");
            lvi.SubItems.AddRange(new string[] {"desc" + i.ToString(), i.ToString()});
            listView1.Items.Add(lvi);
        }

        for (int i = 0; i < 2; i++)
        {
            ListViewItem lvi = new ListViewItem("A2");
            lvi.SubItems.AddRange(new string[] { "desc" + i.ToString(), i.ToString() });
            listView1.Items.Add(lvi);
        }
    }

Answer 1

See MSDN in the Remarks section.

When you remove an item from the
collection, the indexes change for
subsequent items in the collection.
All information about the removed item
is deleted. You can use this method to
remove a specific item from the
collection by specifying the index of
the item to remove from the
collection. To specify the item to
remove instead of the index to the
item, use the Remove method. To remove
all items from the collection, use the
Clear method.

Edit: See Moot’s answer. Link / reference above applies to his/her answer as well.

Edit 2:

Just back the counter up one if you find a match.

    for (int i = 0; i < listView1.Items.Count; i++)
    {
        if (listView1.Items[i].SubItems[0].Text == "A1")
        {
            listView1.Items.RemoveAt(i);
            i--; // Back counter up one
        }
    }
