参考技术A rivate void button1_Click(object sender, EventArgs e)

openFileDialog1.ShowDialog();
foreach (string filename in openFileDialog1.FileNames)


int start = filename.LastIndexOf( '\\');
string str = filename.Substring(start + 1,filename.Length - start - 1);
listView1.Items.Add(new ListViewItem(str));
