使用c＃搜索特定于.rar和.zip的内容

Question

我使用下面的代码搜索.zip

'private void button1_Click(object sender, EventArgs e)
    {

    listView1.Items.Clear();
    listView1.Refresh();
    string[] filePaths = Directory.GetFiles(@textBox1.Text, "*.zip");
    string txtSearch = textBox2.Text;

    foreach (var filePath in filePaths)
    {
        using (ZipArchive archive = ZipFile.OpenRead(filePath))
        {
            foreach (ZipArchiveEntry entry in archive.Entries)
            {
                var position = entry.Name.IndexOf(txtSearch, StringComparison.InvariantCultureIgnoreCase);
                if (position > -1)
                {
                    listView1.Items.Add(entry.Name);
                }
                else
                {
                    MessageBox.Show("FILE NOT FOUND", "ERROR", MessageBoxButtons.OK, MessageBoxIcon.Error);
                }
            }
        }
    }
}'

如果我想在同一时间搜索.zip和.rar，请如何解决这个问题。提前致谢。
