C#富文本控件RichTextBox 使用方法，文本框颜色、字体、格式设置；
以XML文本字符串，用不同颜色、字体、格式显示为例；
程序源码如下：
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Drawing;using System.Windows.Forms; class RichTextUnit    {        public static float m_Size = 16;        public static void SetFont(RichTextBox m_RichTextBox, Color m_Color, bool bBold = false, float Size = 16)        {            m_RichTextBox.SelectionColor = m_Color;            if (bBold)                m_RichTextBox.SelectionFont = new System.Drawing.Font("宋体", Size, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Pixel, ((byte)(134)));            else                m_RichTextBox.SelectionFont = new System.Drawing.Font("宋体", Size, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Pixel, ((byte)(134)));        }        public static void SetText(RichTextBox m_RichTextBox, string strText, Color m_Color, bool bBold = false, float Size = 16)        {            m_RichTextBox.Invoke(((EventHandler)delegate            {                RichTextUnit.SetFont(m_RichTextBox, m_Color, bBold, Size);                m_RichTextBox.SelectedText = strText;            }));        }        public static void SetXmlText(RichTextBox m_RichTextBox, string strText,float Size=16)        {            m_RichTextBox.Invoke(((EventHandler)delegate            {                int iFirstInx = strText.IndexOf("<?");
