  </Request>这个是一个WS的字符串请求，我要怎么写才能将这个请求反序列化成类我自己的代码：
XmlSerializer xs = new XmlSerializer(typeof(ProductInfoReqObject));TextReader tr = new StringReader(ProductInfoReq.Request);ProductInfoReqObject request = (ProductInfoReqObject)xs.Deserialize(tr);会提示：XML 文档(1, 4)中有错误。   在 System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader xmlReader, String encodingStyle, XmlDeserializationEvents events)
   在 System.Xml.Serialization.XmlSerializer.Deserialize(TextReader textReader)
   在 IsmpVnetEngine.ISMPVnetEngine.IsmpVnetEngine.IIsmpVnetEngineSoapBinding.vnetProductInfo(VnetProductInfoReq vnetProductInfoReq)

Answer 1

附上我定义的ProductInfoReqObject，是不是没有加上xml描述的问题
public class ProductInfoReqObject
    {        public string streamingNo;

        public string opFlag;        public string productID;        public string serviceID;        public string SPID;        public string chargingPolicyID;        public string status;        public string statusEffectiveTime;        public string chargingPolicyCN;        public string chargingPolicyEN;        public string corpOnly;        public string releaseTime;        public string subscriptionSyncFlag;        public int needCnfm;        public string packageFlag;        public string portalUseFlag;        public string sellFlag;        public string productDesc;        public string CRBTProductType;        [System.Xml.Serialization.XmlElementAttribute("accessNoAndfeatureStr")]
        public AccessNoAndFeatureStrType[] accessNoAndfeatureStr;        public string[] chargingURL;        public string RRID;        public string productName;        public string trialFlag;        public string subEffectMode;        public string EffectTime;        public string withdrawEffectMode;        public string trialType;        public string trialTerm;        public string PayType;        public string isTrailInPeriod;
    }
    public class AccessNoAndFeatureStrType
    {        public string accessNo;        public string accessNoMatchMode;        public string accessNoType;        public string featureStr;        public string featureStrType;        public string featureStrmatchMode;
    }

Answer 2

你的xml文件中的节点和ProductInfoReqObject类中的字段不匹配啊!!
还有要按序列化的xml文件的格式必须是:
<?xml version="1.0"?>
<ProductInfoReqObject xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <streamingNo>aaa</streamingNo>
  <opFlag>e</opFlag>
  .......
</ProductInfoReqObject>这样就没问题了.

Answer 3

而且根节点必须是ProductInfoReqObject, xmls:xsi="**" xmlns:xsd="**"
其中**是任何不为空的值就行.这样格式的xml才能被反序列化.
