XML 字符串解析

微信红包发送完成后返回xml字符串，解析过程如下：

1、调用解析：

     public ActionResult GetEntityFromXml()
        {
            string str = @"<xml>
<return_code><![CDATA[SUCCESS]]></return_code>
<return_msg><![CDATA[帐号余额不足，请到商户平台充值后再重试]]></return_msg>
<result_code><![CDATA[FAIL]]></result_code>
<err_code><![CDATA[NOTENOUGH]]></err_code>
<err_code_des><![CDATA[帐号余额不足，请到商户平台充值后再重试]]></err_code_des>
<mch_billno><![CDATA[20170114130807a1234567]]></mch_billno>
<mch_id><![CDATA[**********]]></mch_id>
<wxappid><![CDATA[wx****************]]></wxappid>
<re_openid><![CDATA[oPg_***********************]]></re_openid>
<total_amount>100</total_amount>
</xml>";
            System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
            doc.LoadXml(str);
            var rmodel = new WeiXinRedPackgeResultModel();
            Html_Tools.Class1.GetEntityFromXml<WeiXinRedPackgeResultModel>(rmodel, doc);


            return Json(rmodel);
        }

2、解析类（可完善通用）：

public static class Class1
    {
        public static void GetEntityFromXml<T>(this T entity, System.Xml.XmlDocument doc) 
        {
            Dictionary<string, string> Dic = new Dictionary<string, string>();
            System.Xml.XmlNodeList nodelist = doc.DocumentElement.ChildNodes;
            if (nodelist.Count > 0)
            {
                Type t = entity.GetType();
                foreach (System.Xml.XmlElement el in nodelist)//读元素值
                {
                    System.Reflection.PropertyInfo proInfo = t.GetProperty(el.Name);//访问Obj的类型的属性Value的属性信息（propertyInfo）
                    if (proInfo != null)
                    {
                        string str2 = proInfo.PropertyType.Name;
                        if (str2 == null)
                        {
                            goto Label_018A;
                        }
                        if (!(str2 == "DateTime"))
                        {
                            if (str2 == "Boolean")
                            {
                                goto Label_00E9;
                            }
                            if (str2 == "Int64")
                            {
                                goto Label_0134;
                            }
                            goto Label_018A;
                        }
                        proInfo.SetValue(entity, new DateTime(long.Parse(el.InnerText)), null);
                    }
                    continue;
                Label_00E9:
                    proInfo.SetValue(entity, el.InnerText == "1", null);
                    continue;
                Label_0134:
                    proInfo.SetValue(entity, long.Parse(el.InnerText), null);
                    continue;
                Label_018A:
                    proInfo.SetValue(entity, el.InnerText, null);
                }
            }
        }

    }

3、返回的实体类：

 public class WeiXinRedPackgeResultModel
    {
        #region 微信红包返回值

        public string return_code { get; set; }

        public string return_msg { get; set; }

        public string result_code { get; set; }

        public string err_code { get; set; }

        public string err_code_des { get; set; }
        public string mch_billno { get; set; }
        public string mch_id { get; set; }
        public string wxappid { get; set; }
        public string re_openid { get; set; }

        #endregion
    }
