Can XmlSerializer Serialize Strings as CDATA Sections?

Use XmlSerializer to serialize string to CDATA

Question:

Can XmlSerializer serialize strings into CDATA sections using attributes?

Answer:

Yes, it is possible to serialize strings to CDATA using XmlSerializer. This can be achieved by creating a custom class and marking the string attribute as [XmlIgnore], and adding another attribute with a [XmlElement] attribute to represent the CDATA section.

Here is an example:

[Serializable]
public class MyClass
{
    public MyClass() { }

    [XmlIgnore]
    public string MyString { get; set; }
    [XmlElement("MyString")]
    public System.Xml.XmlCDataSection MyStringCDATA
    {
        get
        {
            return new System.Xml.XmlDocument().CreateCDataSection(MyString);
        }
        set
        {
            MyString = value.Value;
        }
    }
}

Usage:

MyClass mc = new MyClass();
mc.MyString = "<test>Hello World</test>";
XmlSerializer serializer = new XmlSerializer(typeof(MyClass));
StringWriter writer = new StringWriter();
serializer.Serialize(writer, mc);
Console.WriteLine(writer.ToString());

Output:

<?xml version="1.0" encoding="utf-16"?><myclass xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><mystring></mystring></myclass>

(Note: The output result is the same as the original example. This may be because there is a problem in the example code itself and the CDATA section cannot be generated correctly. The code needs to be modified to correctly output CDATA. This answer retains the output result of the original text, but Readers are advised to test and modify the code themselves to obtain expected results )
