XmlReader creates empty string C#
I am using StringReader to read an xml stream and then I want to read that stream as XML to Serialize and Desiarilize it. Although it was working fine for some reason my XmlReader variable returns null. The XML as I see is the same as before.
My code is:
StringReader stringReader = new StringReader(result);
stringReader.ReadLine();//omit the first line that contains xml encoding
XmlReader xmlReader = XmlReader.Create(stringReader);
XmlSerializer XmlSerializer = new XmlSerializer(typeof(ResponseDoc));
ResponseDoc XmlResponseDoc = (ResponseDoc)XmlSerializer.Deserialize(xmlReader);
The XML format of the result viariable is
<?xml version="1.0" encoding="utf-8"?>
<ResponseDoc xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<response>
<entitylineNumber>1</entitylineNumber>
<statusCode>Success</statusCode>
<entityUid>0BA0C06E9CBAA3D890D025A37A577DDB074BA9A9</entityUid>
<entityMark>1000000115468</entityMark>
</response>
</ResponseDoc>
My xmlReader variable is null .I also tried to remove the stringReader.ReadLine(); but it didn't change anything. I used that because if the encoding line exists it fails to serialize it.
The ResponseDoc class :
#region XSD Schema
[XmlRoot(ElementName = "Responses", Namespace = "")]
public partial class ResponseDoc
{
private ResponseType[] responseField;
/// <remarks/>
[System.Xml.Serialization.XmlElement(ElementName = "Response", Namespace = "")]
public ResponseType[] response
{
get
{
return this.responseField;
}
set
{
this.responseField = value;
}
}
}
[XmlRoot(ElementName = "Response", Namespace = "")]
public partial class ResponseType
{
private int entitylineNumberField;
private string statusCodeField;
private string uid;
private string markUid;
private ResponseTypeErrors[] responseTypeErrors;
/// <remarks/>
[XmlElement(ElementName = "inv_number", Namespace = "")]
public string entitylineNumber
{
get
{
return this.entitylineNumberField.ToString();
}
set
{
this.entitylineNumberField = int.Parse(value);
}
}
/// <remarks/>
[XmlElement(ElementName = "StatusCode", Namespace = "")]
public string statusCode
{
get
{
return this.statusCodeField;
}
set
{
this.statusCodeField = value;
}
}
[XmlElement(ElementName = "Uid", Namespace = "")]
public string Uid
{
get
{
return this.uid;
}
set
{
this.uid = value;
}
}
[XmlElement(ElementName = "Mark", Namespace = "")]
public string Mark
{
get
{
return this.markUid;
}
set
{
this.markUid = value;
}
}
[XmlElement(ElementName = "Errors", Namespace = "")]
public ResponseTypeErrors[] Errors
{
get
{
return this.responseTypeErrors;
}
set
{
this.responseTypeErrors = value;
}
}
}
[XmlRoot(ElementName = "Errors", Namespace = "")]
public partial class ResponseTypeErrors
{
private ErrorType[] errorField;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("Error")]
public ErrorType[] error
{
get
{
return this.errorField;
}
set
{
this.errorField = value;
}
}
}
[XmlRoot(ElementName = "Error", Namespace = "")]
public partial class ErrorType
{
private string messageField;
private int codeField;
/// <remarks/>

UPDATE: I see that all of you give me answer about my XSD schema. The problem is not to deserialize the XML. My problem is that the variable xmlReader in
XmlReader xmlReader = XmlReader.Create(stringReader);
is {None} altough I have the xml answer in the result variable and I pass it to stringReader.
I don't understand why I some give me negative in my question. I believe it is quite clear what is my problem and I am sure I give enough information about my code.If I knew more I would solve it myself.
I have upload a screenshot as well with the strinReader and the xmlReader
ElementName in System.Xml.Serialization.XmlElement attribute of each property must match the element name in XML. Do the following and you are done with the fix:
ElementName for ResponseDoc class should be ResponseDoc instead of Responses
and in ResponseDoc class ElementName for response property should be response instead of Response:
ResponseDoc class should look like:
[XmlRoot(ElementName = "ResponseDoc", Namespace = "")]
public partial class ResponseDoc
{
private ResponseType[] responseField;
/// <remarks/>
[System.Xml.Serialization.XmlElement(ElementName = "response", Namespace = "")]
public ResponseType[] response
{
get
{
return this.responseField;
}
set
{
this.responseField = value;
}
}
}
and in ResponseType class make sure ElementName for each property is according to XML:
ElementName for entitylineNumber property should be entitylineNumber instead of inv_number
ElementName for statusCode property should be statusCode instead of StatusCode
same rule for other properties as below:
public partial class ResponseType
{
private int entitylineNumberField;
private string statusCodeField;
private string uid;
private long entityMark;
[XmlElement(ElementName = "entitylineNumber", Namespace = "")]
public string entitylineNumber
{
get
{
return this.entitylineNumberField.ToString();
}
set
{
this.entitylineNumberField = int.Parse(value);
}
}
/// <remarks/>
[XmlElement(ElementName = "statusCode", Namespace = "")]
public string statusCode
{
get
{
return this.statusCodeField;
}
set
{
this.statusCodeField = value;
}
}
[XmlElement(ElementName = "entityUid", Namespace = "")]
public string Uid
{
get
{
return this.uid;
}
set
{
this.uid = value;
}
}
[XmlElement(ElementName = "entityMark", Namespace = "")]
public string EntityMark
{
get
{
return this.entityMark.ToString();
}
set
{
this.entityMark = long.Parse(value);
}
}
}
