使用XmlMediaTypeFormatter或其他反序列化的ReadAsAsync类

Question

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>asjdkfljasl;kdf</id>
    <operation>query</operation>
    <object>jsdkfjsakldjakl</object>
    ...
</jobInfo>

I have the following code that makes the POST request and works successfully, but cannot deserialize into my class.

client.DefaultRequestHeaders.Add("X-SFDC-Session", binding.SessionHeaderValue.sessionId);
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", binding.SessionHeaderValue.sessionId);

var content = new StringContent(createJobXml, Encoding.UTF8, "application/xml");
content.Headers.ContentType = new MediaTypeHeaderValue("application/xml");

HttpResponseMessage response = await client.PostAsync(
    $"https://{SERVER_INSTANCE}.salesforce.com/services/async/43.0/job", content
);
response.EnsureSuccessStatusCode();

jobInfo job = await response.Content.ReadAsAsync<jobInfo >(new List<MediaTypeFormatter>() {
    new XmlMediaTypeFormatter { UseXmlSerializer = true },
    new JsonMediaTypeFormatter()
});

But I get the error

No MediaTypeFormatter is available to read an object of type 'jobInfo ' from content with media type 'application/xml',

my jobInfo was generated using xsd.exe doc.xml , xsd.exe doc.xsd /classes

[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.6.81.0")]

[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://www.force.com/2009/06/asyncapi/dataload", IsNullable = false)]
public partial class jobInfo
{
    private string idField;
    private string operationField;
    private string objectField;
    ...
    public string id
    {
        get {
            return this.idField;
        }
        set {
            this.idField = value;
        }
    }
    public string operation
    {
        get {
            return this.operationField;
        }
        set {
            this.operationField = value;
        }
    }
    ...
 }

What am I missing in order to deserialize this correctly?

This suggests that I should just read it as a string:

How to use HttpClient to read an XML response?

but this suggests that it should "just work"

HttpClient ReadAsAsync<Type> only deserializing part of the response

I have also tried (was using class Bulkv1Job before I used xsd to convert the xml to a class)

[DataContract]
public class Bulkv1Job
{
    [DataMember]
    string id { get; set; }
    [DataMember]
    string operation { get; set; }
    [DataMember]
    string @object { get; set; }
    ...
}

and

[XmlRoot("jobInfo")]
public class Bulkv1Job
{
    [XmlElement("id")]
    string id { get; set; }
    [XmlElement("operation")]
    string operation { get; set; }
    ...
}

Answer 1

Hmmm I'm not an expert with soap but it should have decorators like [DataMember] on your properties and [DataContract(NameSpace="jobInfo")] on your class if I remember well. You can see that in the first suggestion you provide the guy use [XmlRoot] and [XmlElement]

You can also see WCF Datacontract, some fields do not deserialize , maybe it would help you

Answer 2

After testing with

var s = await response.content.readasstringasync();
var buffer = encoding.utf8.getbytes(s);
using (var stream = new memorystream(buffer)) {
    var serializer = new xmlserializer(typeof(jobinfo)); // FAILED LINE
    var jobinfo = (jobinfo)serializer.deserialize(stream);
    //then do whatever you want
    return jobinfo;
}

I found that the serializer failed on the above line due to a class protection error. Ensuring the jobInfo class was public and accessible, the error went away and the deserialize(stream) worked.

Removing that code and using readAsAsync<jobInfo>(...) worked appropriately afterwards.
