How to add a "int array" like a subitem of a listview

the error message clearly tells you what the issue is, cannot convert Convert being the key word , from into to ListViewItem.ListViewSubItem doing a msdn search on the error or google would tell you the data type that SubItem is expecting.. I would refresh yourself on the .ToString() extension method as well as the Convert.ToString()` method when you get a chance — MethodMan

for (Int32 i = 0; i < varintx.Length; ++i)
{
    ListViewItem item = new ListViewItem();
    item.SubItems.Add(varintx[i].ToString());

    myListVIew.Items.Add(item);
}

You have to convert your int values to string before passing them to the ListViewItem. So your code excerpt should be rewritten as follows:

item1.SubItems.Add(varintx[x].ToString());
