Can't Deserialize XML

问题:

I am trying to deserialize the following XML:

<?xml version="1.0" encoding="UTF-8"?> <jobInfo xmlns="http://www.force.com/2009/06/asyncapi/dataload"> <id>750x0000000005LAAQ</id> <operation>insert</operation> <object>Contact</object> <createdById>005x0000000wPWdAAM</createdById> <createdDate>2009-09-01T16:42:46.000Z</createdDate> <systemModstamp>2009-09-01T16:42:46.000Z</systemModstamp> <state>Open</state> <concurrencyMode>Parallel</concurrencyMode> <contentType>CSV</contentType> <numberBatchesQueued>0</numberBatchesQueued> <numberBatchesInProgress>0</numberBatchesInProgress> <numberBatchesCompleted>0</numberBatchesCompleted> <numberBatchesFailed>0</numberBatchesFailed> <numberBatchesTotal>0</numberBatchesTotal> <numberRecordsProcessed>0</numberRecordsProcessed> <numberRetries>0</numberRetries> <apiVersion>28.0</apiVersion> </jobInfo> 

I have created this object:

public class JobInfo {     public string xmlns { get; set; }     public string id { get; set; }     public string operation { get; set; }     public string @object { get; set; }     public string createdById { get; set; }     public string createdDate { get; set; }     public string systemModstamp { get; set; }     public string state { get; set; }     public string concurrencyMode { get; set; }     public string contentType { get; set; }     public string numberBatchesQueued { get; set; }     public string numberBatchesInProgress { get; set; }     public string numberBatchesCompleted { get; set; }     public string numberBatchesFailed { get; set; }     public string numberBatchesTotal { get; set; }     public string numberRecordsProcessed { get; set; }     public string numberRetries { get; set; }     public string apiVersion { get; set; } }  public class RootObject {     public JobInfo jobInfo { get; set; } } 

And, I am using this code:

XmlSerializer serializer = new XmlSerializer(typeof(RootObject)); StringReader rdr = new StringReader(response); RootObject resultingMessage = (RootObject)serializer.Deserialize(rdr); 

However, I get this error:

There is an error in XML document (1, 40).  {"<jobInfo xmlns='http://www.force.com/2009/06/asyncapi/dataload'> was not expected."} 

How can I account for the xmlns attribute? My code has it as a property (thus, it fails)...

回答1:

Try using the XmlRootAttribute to specify the Namespace.

[XmlRoot("jobInfo", Namespace = "http://www.force.com/2009/06/asyncapi/dataload")] public class JobInfo {     [XmlElement("id")]     public string Id { get; set; }      [XmlElement("operation")]     public string Operation { get; set; }      [XmlElement("object")]     public string Object { get; set; }      [XmlElement("createdById")]     public string CreatedById { get; set; }      [XmlElement("createdDate")]     public DateTime CreatedDate { get; set; }      [XmlElement("systemModstamp")]     public DateTime SystemModstamp { get; set; }      [XmlElement("state")]     public string State { get; set; }      [XmlElement("concurrencyMode")]     public string ConcurrencyMode { get; set; }      [XmlElement("contentType")]     public string ContentType { get; set; }      [XmlElement("numberBatchesQueued")]     public string NumberBatchesQueued { get; set; }      [XmlElement("numberBatchesInProgress")]     public string NumberBatchesInProgress { get; set; }      [XmlElement("numberBatchesCompleted")]     public string NumberBatchesCompleted { get; set; }      [XmlElement("numberBatchesFailed")]     public string NumberBatchesFailed { get; set; }      [XmlElement("numberBatchesTotal")]     public string NumberBatchesTotal { get; set; }      [XmlElement("numberRecordsProcessed")]     public string numberRecordsProcessed { get; set; }      [XmlElement("numberRetries")]     public string NumberRetries { get; set; }      [XmlElement("apiVersion")]     public string ApiVersion { get; set; } } 

Code:

var xml = @"<?xml version=""1.0"" encoding=""UTF-8""?> <jobInfo xmlns=""http://www.force.com/2009/06/asyncapi/dataload"">     <id>750x0000000005LAAQ</id>     <operation>insert</operation>     <object>Contact</object>     <createdById>005x0000000wPWdAAM</createdById>     <createdDate>2009-09-01T16:42:46.000Z</createdDate>     <systemModstamp>2009-09-01T16:42:46.000Z</systemModstamp>     <state>Open</state>     <concurrencyMode>Parallel</concurrencyMode>     <contentType>CSV</contentType>     <numberBatchesQueued>0</numberBatchesQueued>     <numberBatchesInProgress>0</numberBatchesInProgress>     <numberBatchesCompleted>0</numberBatchesCompleted>     <numberBatchesFailed>0</numberBatchesFailed>     <numberBatchesTotal>0</numberBatchesTotal>     <numberRecordsProcessed>0</numberRecordsProcessed>     <numberRetries>0</numberRetries>     <apiVersion>28.0</apiVersion> </jobInfo>";  var serializer = new XmlSerializer(typeof(JobInfo));  JobInfo jobInfo;  using(var stream = new StringReader(xml)) using(var reader = XmlReader.Create(stream)) {     jobInfo = (JobInfo)serializer.Deserialize(reader); } 

回答2:

Currently your code is expecting the xmlns as element, not the attribute.

You should add the XmlSerialization attributes to your class, like this:

[XmlRoot("jobInfo", Namespace="http://www.force.com/2009/06/asyncapi/dataload"] public class JobInfo {     [XmlAttribute]     public string xmlns { get; set; }     [XmlElement(ElementName = "id")]     public string id { get; set; }     .... } 

You can find more information in MSDN articles:

• Controlling XML Serialization Using Attributes
• Examples of XML Serialization

Add the namespace

  [XmlRoot("jobInfo",Namespace = "http://www.force.com/2009/06/asyncapi/dataload")]   public class JobInfo   {      // get rid of the xmlns property      // other properties stay   }  // there is no rootobject, JobInfo is your root XmlSerializer serializer = new XmlSerializer(typeof(JobInfo)); StringReader rdr = new StringReader(response); JobInfo resultingMessage = (JobInfo)serializer.Deserialize(rdr);
