                {
                    doc.designMode = "on";
                }
            }
        }

            {
                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;
                }
            }
        }

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。
