XML读取信息并显示

这个类命名叫Message.cs

namespace Common
{
    public class Message
    {
        /// <summary>
        /// 信息编号
        /// </summary>
        private string messagecode = string.Empty;

        public string MessageCode
        {
            get { return messagecode; }
        }

        /// <summary>
        /// 信息描述
        /// </summary>
        private string messagedata = string.Empty;

        public string MessageData
        {
            get { return messagedata; }
        }

        public void Setmessagedata(string value)
        {
            messagedata = value;
        }
        public Message(string mc,int x)
        {
            this.messagedata = mc;
        }
        /// <summary>
        /// 构造函数
        /// </summary>
        /// <param name="mc">信息编号</param>
        public Message(string mc)
        {
            this.messagecode = mc;
            using (System.Data.DataSet ds = XMLHelp.ConvertXMLFileToDataSet(System.Configuration.ConfigurationManager.AppSettings["MessagePath"]))
            {
                if (ds.Tables[0] != null)
                {
                    for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
                    {
                        if (ds.Tables[0].Rows[i]["Code"].ToString() == mc)
                        {
                            this.messagedata = ds.Tables[0].Rows[i]["Content"].ToString();
                            break;
                        }
                    }
                }
            }
        }
    }
}

下面这个类命名叫：XMLHelp.cs

都放在DAL文件里面，自己修改命名空间

using System.Text;
using System.Xml;

using System.Web;

            }
            catch (System.Exception ex)

}

如：后台弹窗：

string ID = Request["ID"];
                    if (!Function.CheckStr(ID, 1))
                    {
                        Function.ShowMsgBox(new Message("M0008").MessageData, "baoming.aspx", false);  //掉出方法，然后给定参数，直接执行就OK
                    }

在项目根目录有个XML文件夹，里面有个Message.xml文件，内容如下：

这个XML文件里的Code自己定义，content就是你要读取的内容，需要的时候匹配好Code字段就好了。就是这么简单
