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:\Development\Framework\TestApplication\XMLScript\XMLScript\XMLFile.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; }
