I have an XMLDocument which i am deserializing into object in my C# code. It works fine until i have nodes like below,

  <Name>ABC</Name>

  <Message>Invalid Name</Message>

In the above scenario what i get inside my C# object would be Name = ABC and Message = Invalid Name.

But now i have a requirement to read a complete XML node inside XMLDocument. Which is like this,

<ReadXML><fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">

          <entity name="customerproduct">

            <attribute name="customerproductid" />

            <attribute name="name" />

            <attribute name="createdon" />

            <attribute name="customertype" />

            <attribute name="custodian_customerproductid" />

            <attribute name="accountnumber" />

            <order attribute="name" descending="false" />

            <filter type="and">

              <condition attribute="productgroup" operator="eq" uiname="Credit Cards" uitype="productgroup" value="{12344}" />

              <condition attribute="customer" operator="eq" uiname="abc xyz" uitype="contact" value="{1234}" />

            </filter>

          </entity>

        </fetch></ReadXML>

I have an object ReadXML inside my C# code and i was looking to get complete XML that is inside ReadXML node as an string inside my ReadXML variable.

something like this,

string ReadXML = "<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">

          <entity name="customerproduct">

            <attribute name="customerproductid" />

            <attribute name="name" />

            <attribute name="createdon" />

            <attribute name="customertype" />

            <attribute name="custodian_customerproductid" />

            <attribute name="accountnumber" />

            <order attribute="name" descending="false" />

            <filter type="and">

              <condition attribute="productgroup" operator="eq" uiname="Credit Cards" uitype="productgroup" value="{12344}" />

              <condition attribute="customer" operator="eq" uiname="abc xyz" uitype="contact" value="{1234}" />

            </filter>

          </entity>

        </fetch>"

Inside my Code i am doing this,

 XmlDocument doc = new XmlDocument();



        doc.Load(@"D:DevelopmentFrameworkTestApplicationXMLScriptXMLScriptXMLFile.xml");





        string XML = doc.InnerXml;

        operationTitle.Text = "Stop Lost Card"; ;

        System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(MyOperation));

        MemoryStream memStream = new MemoryStream(Encoding.UTF8.GetBytes(vrp_XML));

        MyOperation = (MyOperation)serializer.Deserialize(memStream);

And Inside MyOperation Class, i have ReadXML like this,

[XmlElement(ElementName = "ReadXML")]

public string ReadXML { get; set; }

Whenever i try to read the XML into the string i get the following error,

    System.InvalidOperationException was unhandled

  HResult=-2146233079

  Message=There is an error in XML document (1, 1329).

The problem is that we cannot serialize/deserialize a complex type to string. Instead we can define our own type and implement IXmlSerializable interface to provide our own implementation.

Below I've defined a MyString class to implement the same. In ReadXml method I'm using innerXml. You may use the outerXml as well.

public class MyString : IXmlSerializable

{

    string _xmlString;

    public XmlSchema GetSchema()

    {

        return null;

    }



    public void ReadXml(XmlReader reader)

    {

        reader.MoveToContent();



        Boolean isEmptyElement = reader.IsEmptyElement;

        if (!isEmptyElement)

        {

            _xmlString = reader.ReadInnerXml();

        }

    }



    public void WriteXml(XmlWriter writer)

    {

        writer.WriteString(_xmlString);

    }

}

The property ReadXML will now be of type MyString instead of string.

[XmlElement(ElementName = "ReadXML")]

public MyString ReadXML { get; set; }

Ref: I got the idea from the following Stackoverflow question https://stackoverflow.com/a/22106996/643318

var xml=File.ReadAllText(@"D:DevelopmentFrameworkTestApplicationXMLScriptXMLScriptXMLFile.xml")

var xml=File.ReadAllText(@"D:XMLFile.xml");



var xml_l=xml.ToLower();



var ind_1=xml_l.IndexOf("<fetch");

var ind_2=xml_l.IndexOf("</fetch",ind_1);



var xml_fetch=xml.Substring(ind_1, ind_2 - ind_1+8);
