Highlight a word or phrase with a color different from all the other selections in a RichTextBox text?

private class TextSearcher
{
    private BindingSource m_bsMatches = null;
    private RichTextBox m_Rtb = null;

    public TextSearcher(RichTextBox rtb) : this(rtb, Color.Yellow, Color.Red) { }
    public TextSearcher(RichTextBox rtb, Color selectionColor, Color currentColor)
    {
        this.m_Rtb = rtb;
        SelectionColor = selectionColor;
        CurrentColor = currentColor;
    }

    public string CurrentKeywords { get; private set; } = string.Empty;
    public bool CaseSensitive { get; set; } = true;
    public int CurrentIndex => m_bsMatches.Position;
    public Match CurrentMatch => (Match)m_bsMatches.Current;
    public MatchCollection Matches { get; private set; }
    public Color SelectionColor { get; set; }
    public Color CurrentColor { get; set; }

    public void GotoMatch(int position)
    {
        SelectText(false);
        this.m_bsMatches.Position = Math.Max(Math.Min(this.m_bsMatches.Count, position), 0);
        SelectText(true);
    }

    public void NextMatch()
    {
        SelectText(false);

        if (this.m_bsMatches != null && m_bsMatches.Position == this.m_bsMatches.Count - 1) 
        {
            this.m_bsMatches.MoveFirst();
        }
        else 
        {
            this.m_bsMatches.MoveNext(); 
        }

        SelectText(true);
    }

    public void PreviousMatch()
    {
        SelectText(false);

        if (this.m_bsMatches != null && this.m_bsMatches.Position > 0) 
        {
            this.m_bsMatches.MovePrevious();
        }
        else 
        {
            this.m_bsMatches.MoveLast(); 
        }

        SelectText(true);
    }

    public int Search(string keywords)
    {
        if (CurrentKeywords.Equals(keywords)) return Matches.Count;
        this.m_bsMatches?.Dispose();
        CurrentKeywords = keywords;

        var options = RegexOptions.Multiline |
                     (CaseSensitive ? RegexOptions.IgnoreCase : RegexOptions.None);
        Matches = Regex.Matches(this.m_Rtb.Text, keywords, options);

        if (Matches != null) 
        {
            this.m_Rtb.SelectAll();
            this.m_Rtb.SelectionColor = this.m_Rtb.ForeColor;
            this.m_Rtb.SelectionStart = 0;
            this.m_bsMatches = new BindingSource(Matches, null);
            SelectKeywords();
            return Matches.Count;
        }

        return 0;
    }

    private void SelectKeywords()
    {
        foreach (Match m in Matches) 
        {
            SelectText(false);
            NextMatch();
        }

        this.m_bsMatches.MoveFirst();
    }

    private void SelectText(bool current)
    {
        this.m_Rtb.Select(CurrentMatch.Index, CurrentMatch.Length);
        this.m_Rtb.SelectionColor = current ? CurrentColor : SelectionColor;
    }
}

使用中：

numericUpDown1.Maximum = rbsearcherhl.Search(textBox1.Text);

例如，textBox1中的文本为"System"，但是在我要搜索多个单词的搜索中，您添加了,,，例如System,,public或system,,public,,World

但是在TextSearcher调用中的搜索功能中，使用符号|来搜索多个单词>

如何在搜索器中进行更改，使符号像我的,,？

在示例中，您键入System|using来搜索多个单词但我想通过键入System,,using或System,,using,,public,,World

搜索多个单词

代替|如何使用,,

作为参考，此代码来自以下问题的答案：以一个不同于RichTextBox文本中所有其他选择的颜色突出显示一个单词或短语？使用System.Collections ....

Answer 1

将用户在您的文本框1（或您所说的文本框）中键入的System,,public用作[]并提供给TextSearcher，>

Search(textbox1.Text.Replace("|", "\\|").Replace(",,", "|"))
