在C＃中突出显示RichTextBox的语法 [英] Syntax highlighting a RichTextBox in C#

问题描述

我有一些代码可以为richtextbox中的某些文本添加颜色，目前它应该做的是富文本框中每个单词的字符颜色，但是由于某种原因它会使一些字符仍然是黑色的。



这是timer1 tick方法

I have some code that should color some text in a richtextbox, currently what it should do, is character by character color every word in the richtextbox, but it leaves some characters still black at the end for some reason.

This is the timer1 tick method

private void timer1_Tick(object sender, EventArgs e)
        {
            foreach (RichTextBox rtb in Editor.Values)
            {
                int pos = 0;
                foreach(string ln in rtb.Lines)
                {
                    Color[] Syntax = EditorTools.ParseString(ln);
                    int cur = 0;
                    foreach (char chr in ln)
                    {
                        rtb.SelectionStart = pos;
                        rtb.SelectionLength = 1;
                        rtb.SelectionColor = Syntax[cur];
                        cur++;
                        pos++;
                    }
                }
            }
        }

这是ParseString方法返回颜色数组

And this is the ParseString method which returns a Color array

public static Color[]ParseString(string raw)
        {
            int len = 0;
            foreach(char chr in raw)
            {
                len++;
            }
            Color[] ret = new Color[len];
            string[] parsed = Regex.Split(raw, " ");
            for (int i = 0;i < len;i++)
            {
                ret[i] = Color.Green;
            }
            return ret;
        }
