推荐答案

由别人说是有可能的重复与前面一个问题。但是，请在下面看到一个code片段。你不必让你以改变其格式附加文本的长度，只需设置格式您将追加之前。如果您在文本框中有大量的文字这样（我认为）提供更好的性能。

as stated by others there is a possible duplication with an earlier question. However, please see a code snippet below. You don’t have to get the length of the text you append in order to change its formatting, just set the format before you append. This (i think) gives better performance if you have a lot of text in the textbox.

这将工作，只要有在用户文本框中没有选择，然后奇怪的事情会发生，我无法解释。也许别人可以启发我们吗？同样的问题出现在<一个提出的解决方案href=\"http://stackoverflow.com/questions/2527700/change-color-of-text-within-a-winforms-richtextbox\">http://stackoverflow.com/questions/2527700/change-color-of-text-within-a-winforms-richtextbox.我取代了：你以后过的用户名只是为了让我的code样品的日期时间的东西更容易地工作，这可以很容易地在分割进行修改。

This will work as long as there are no selections in the textbox by the user, then strange things will happen that I cannot explain. Perhaps someone else can enlighten us? The same problem appears with the solution proposed in http://stackoverflow.com/questions/2527700/change-color-of-text-within-a-winforms-richtextbox. I replaced the ":" you had after the user name just to get my code sample to work more easily with the DateTime thing, this can be easily modified in the "Split".

       private void AddText(string text)
    {
        string[] str = text.Split(new string[] { ";" }, StringSplitOptions.RemoveEmptyEntries);

        if (str.Length == 2)
        {
            richTextBox1.DeselectAll();
            richTextBox1.SelectionFont = new Font(richTextBox1.SelectionFont, FontStyle.Bold);
            richTextBox1.AppendText(Environment.NewLine + str[0] + ";");
            richTextBox1.SelectionFont = new Font(richTextBox1.SelectionFont, FontStyle.Regular);
            richTextBox1.AppendText(str[1]);
        } // Else?? Well, do something else..
    }

和调用：

        private void button1_Click(object sender, EventArgs e)
    {
        AddText(DateTime.Now.ToString() + " - Mike; Did something");

    }
