一、启用编辑模式、 浏览模式 及 自动换行         /// <summary>        /// 编辑模式        /// </summary>        public void EditMode()        {            if (this.webBrowser.Document != null)            {                mshtml.IHTMLDocument2 doc = this.webBrowser.Document.DomDocument as mshtml.IHTMLDocument2;                if (doc != null)                {                    doc.designMode = "on";                }            }        }        /// <summary>        /// 启用浏览模式        /// </summary>        public void BrowseMode()        {            if (this.webBrowser.Document != null)            {                mshtml.IHTMLDocument2 doc = this.webBrowser.Document.DomDocument as mshtml.IHTMLDocument2;                if (doc != null)                {                    doc.designMode = "off";                }            }        }        /// <summary>        /// 设置自动换行        /// </summary>        /// <param name="value"></param>        public void SetAutoWrap(bool value)        {            mshtml.HTMLDocument doc = this.webBrowser.Document.DomDocument as mshtml.HTMLDocument;            if (doc != null)            {                mshtml.HTMLBody body = doc.body as mshtml.HTMLBody;                if (body != null)                {                    body.noWrap = !value;                }            }        }在编辑模式下，可以使用：  this.webBrowser.Document.ExecCommand([string],[bool],[object]);方法来操作WebBrowser中的HTML。其中第一个字符串类型的参数为：要执行的命令的名称 。第二个布尔类型的参数为： 是否向用户显示命令特定的对话框或消息框。第三个Object类型的参数为：要使用该命令分配的值。并非适用于所有命令。常见的命令有：        private const string HTML_COMMAND_BOLD = "Bold";                       //加粗        private const string HTML_COMMAND_UNDERLINE = "Underline";             //下划线        private const string HTML_COMMAND_ITALIC = "Italic";                   //斜体        private const string HTML_COMMAND_SUBSCRIPT = "Subscript";             //下标        private const string HTML_COMMAND_SUPERSCRIPT = "Superscript";         //上标        private const string HTML_COMMAND_STRIKE_THROUGH = "StrikeThrough";    //删除线        private const string HTML_COMMAND_FONT_NAME = "FontName";              //字体        private const string HTML_COMMAND_FONT_SIZE = "FontSize";              //字号        private const string HTML_COMMAND_FORE_COLOR = "ForeColor";            //字体前景色        private const string HTML_COMMAND_BACK_COLOR = "BackColor";            //字体背景色        private const string HTML_COMMAND_INSERT_FORMAT_BLOCK = "FormatBlock"; //加粗        private const string HTML_COMMAND_REMOVE_FORMAT = "RemoveFormat";      //清楚样式        private const string HTML_COMMAND_JUSTIFY_LEFT = "JustifyLeft";        //文本左对齐        private const string HTML_COMMAND_JUSTIFY_CENTER = "JustifyCenter";    //文本中间对齐        private const string HTML_COMMAND_JUSTIFY_RIGHT = "JustifyRight";      //文本右对齐        private const string HTML_COMMAND_JUSTIFY_FULL = "JustifyFull";        //文本两端对齐        private const string HTML_COMMAND_INDENT = "Indent";                   //增大缩进量        private const string HTML_COMMAND_OUTDENT = "Outdent";                 //减小缩进量        private const string HTML_COMMAND_INSERT_LINE = "InsertHorizontalRule";//插入分割符        private const string HTML_COMMAND_INSERT_LIST = "Insert{0}List"; // replace with (Un)Ordered 插入项目符号或项目编号        private const string HTML_COMMAND_INSERT_IMAGE = "InsertImage";         //插入图像        private const string HTML_COMMAND_INSERT_LINK = "CreateLink";           //插入链接        private const string HTML_COMMAND_REMOVE_LINK = "Unlink";               //移除链接        private const string HTML_COMMAND_TEXT_CUT = "Cut";                     //剪切        private const string HTML_COMMAND_TEXT_COPY = "Copy";                   //复制        private const string HTML_COMMAND_TEXT_PASTE = "Paste";                 //粘贴        private const string HTML_COMMAND_TEXT_DELETE = "Delete";               //删除        private const string HTML_COMMAND_TEXT_UNDO = "Undo";                   //撤销        private const string HTML_COMMAND_TEXT_REDO = "Redo";                   //恢复        private const string HTML_COMMAND_TEXT_SELECT_ALL = "SelectAll";        //全选        private const string HTML_COMMAND_TEXT_UNSELECT = "Unselect";           //取消选择        private const string HTML_COMMAND_TEXT_PRINT = "Print";                 // 打印        private const string HTML_COMMAND_EDITMODE = "EditMode";                // 编辑模式        private const string HTML_COMMAND_BROWSEMODE = "BrowseMode";            // 浏览模式        private const string HTML_COMMAND_OVERWRITE = "OverWrite";             //转换插入、覆写模式
