C＃程序从列表框中删除停用词

Question

你好，我是C＃编程的新手，我尝试编写一些代码来删除保存在列表框中的文本中的停用词，但是当我调试我的程序时，停用词按钮什么都不做 - ＆gt;这是我如何将文本保存在列表中

private void button5_Click(object sender, EventArgs e)
{

  var r = new StreamReader(textBox1.Text);
    String s;
    Hashtable freq = new Hashtable();
    String[] stop = { "abc", "def", "xyz" };
    while ((s = r.ReadLine()) != null)
    {
        String[] v = s.Split(' ');
        for (int i = 0; i < v.Length; ++i)
        {
            if (freq.ContainsKey(v[i]))
            {
                freq[v[i]] = (int)freq[v[i]] + 1;
            }
            else
            {
                freq[v[i]] = 1;
            }
        }
    }
    r.Close();
    /// write results
    var w = new StreamWriter("richTextBox1", true);
    foreach (String x in freq.Keys)
    {
        if (stop.Contains(x) == false)
        {
            listBox1.Items.Add(x + ": " + freq[x]);
        }
    }
    w.Close();
}

这就是我想从列表中删除停止词的任何帮助请：＆＃39;（

        {
            foreach (string q in Stop_words)
            {
                if (bow.ContainsKey(q))
                { bow.Remove(q); }
            }
            foreach (DictionaryEntry de in bow)
            {
                listBox2.Items.Add(de.Key + " : " + de.Value);
