Remember before using drag and drop you need to set the control to

C#

listView1.AllowDrop = true;

C#

private void Form1_DragEnter(object sender, DragEventArgs e)
{
    if (e.Data.GetDataPresent(DataFormats.FileDrop))
    {
        e.Effect = DragDropEffects.Copy;
    }
    else
    {
        e.Effect = DragDropEffects.None;
    }
}

private void Form1_DragDrop(object sender, DragEventArgs e)
{
    if (e.Data.GetDataPresent(DataFormats.FileDrop))
    {
        string[] filePaths = (string[])(e.Data.GetData(DataFormats.FileDrop));
        foreach (string fileLoc in filePaths)
        {
            // Code to read the contents of the text file
            if (File.Exists(fileLoc))
            {
                using (TextReader tr = new StreamReader(fileLoc))
                {
                    MessageBox.Show(tr.ReadToEnd());
                }
            }

        }
    }
}
