I am receiving the following error trying to deserialize xml. This produces the error:
XmlSerializer serializer = new XmlSerializer(typeof(PrivateOptionsAPIResponse));
var result = serializer.Deserialize(streamReader);
Exception:
System.InvalidOperationException was caught
Message=There is an error in XML document (0, 0)
InnerException: System.Xml.XmlException
Message=Root element is missing
Source=System.Xml
I am not sure how to correct the problem. Request returns the following XML:
<PrivateOptionsAPIResponse>
<CountiesForPostalCodeResponse>
<Counties>
<County>
<CountyName>PRINCE WILLIAM</CountyName>
<StateCode>VA</StateCode>
</County>
<County>
<CountyName>MANASSAS CITY</CountyName>
<StateCode>VA</StateCode>
</County>
<County>
<CountyName>MANASSAS PARK CITY</CountyName>
<StateCode>VA</StateCode>
</County>
</Counties>
</CountiesForPostalCodeResponse>
</PrivateOptionsAPIResponse>
I used xsd.exe to generate a class. The definition on PrivateOptionsAPIResponse (generated by xsd.exe tool) shows:
public partial class PrivateOptionsAPIResponse {
private object itemField;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("CountiesForPostalCodeResponse", typeof(ZipCodeValidationResponse))]
[System.Xml.Serialization.XmlElementAttribute("PlanDetailsForIndividualOrFamilyResponse", typeof(IndividualPlanBenefitResponse))]
[System.Xml.Serialization.XmlElementAttribute("PlansForIndividualOrFamilyResponse", typeof(IndividualPlanQuoteResponse))]
[System.Xml.Serialization.XmlElementAttribute("ProductDetailsForSmallGroupResponse", typeof(SmallGroupProductBenefitResponse))]
[System.Xml.Serialization.XmlElementAttribute("ProductsForSmallGroupResponse", typeof(SmallGroupProductQuoteResponse))]
public object Item {
get {
return this.itemField;
}
set {
this.itemField = value;
}
}
}
If I then browse to ZipCodeValidationResponse definition it shows this:
public partial class ZipCodeValidationResponse {
private CountyType[] countiesField;
/// <remarks/>
[System.Xml.Serialization.XmlArrayItemAttribute("County", IsNullable=false)]
public CountyType[] Counties {
get {
return this.countiesField;
}
set {
this.countiesField = value;
}
}
}
If I then browse definition on CountyType I see this:
public partial class CountyType {
private string countyNameField;
private StateAbbreviationType stateCodeField;
/// <remarks/>
public string CountyName {
get {
return this.countyNameField;
}
set {
this.countyNameField = value;
}
}
/// <remarks/>
public StateAbbreviationType StateCode {
get {
return this.stateCodeField;
}
set {
this.stateCodeField = value;
}
}
}
----------Working solution----------------:
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
string status = ((HttpWebResponse)response).StatusDescription;
if(status == "OK")
{
using (Stream responseStream = response.GetResponseStream())
{
using (StreamReader reader = new StreamReader(responseStream))
{
var xmlSerializer = new XmlSerializer(typeof(PrivateOptionsAPIResponse));
var privateOptionsAPIResponse = xmlSerializer.Deserialize(reader) as PrivateOptionsAPIResponse;
}
}
}
}
