XML CDATA Encoding

Question

I am trying to build an XML document in C# with CDATA to hold the text inside an element. For example..

<email>
<![CDATA[test@test.com]]>
</email>

However, when I get the InnerXml property of the document, the CDATA has been reformatted so the InnerXml string looks like the below which fails.

<email>
&lt;![CDATA[test@test.com]]&gt;
</email>

How can I keep the original format when accessing the string of the XML?

Cheers

Answer 1

Don't use InnerText : use XmlDocument.CreateCDataSection :

using System;
using System.Xml;

public class Test
{
    static void Main()
    {
        XmlDocument doc = new XmlDocument();
        XmlElement root = doc.CreateElement("root");
        XmlElement email = doc.CreateElement("email");
        XmlNode cdata = doc.CreateCDataSection("test@test.com");

        doc.AppendChild(root);
        root.AppendChild(email);
        email.AppendChild(cdata);

        Console.WriteLine(doc.InnerXml);
    }
}

With XmlDocument :

    XmlDocument doc = new XmlDocument();
    XmlElement email = (XmlElement)doc.AppendChild(doc.CreateElement("email"));
    email.AppendChild(doc.CreateCDataSection("test@test.com"));
    string xml = doc.OuterXml;

or with XElement :

    XElement email = new XElement("email", new XCData("test@test.com"));
    string xml = email.ToString();
