XmlSerializer를 사용하여 문자열을 CDATA로 직렬화하는 방법은 무엇입니까?

.Net XmlSerializer를 사용하여 문자열을 CDATA로 직렬화하는 일종의 속성을 통해 가능합니까?

[XmlRoot("root")]
public class Sample1Xml
{
    internal Sample1Xml()
    {
    }

    [XmlElement("node")]
    public NodeType Node { get; set; }

    #region Nested type: NodeType

    public class NodeType
    {
        [XmlAttribute("attr1")]
        public string Attr1 { get; set; }

        [XmlAttribute("attr2")]
        public string Attr2 { get; set; }

        [XmlIgnore]
        public string Content { get; set; }

        [XmlText]
        public XmlNode[] CDataContent
        {
            get
            {
                var dummy = new XmlDocument();
                return new XmlNode[] {dummy.CreateCDataSection(Content)};
            }
            set
            {
                if (value == null)
                {
                    Content = null;
                    return;
                }

                if (value.Length != 1)
                {
                    throw new InvalidOperationException(
                        String.Format(
                            "Invalid array length {0}", value.Length));
                }

                Content = value[0].Value;
            }
        }
    }

    #endregion
}

[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;
        }
    }
}

용법:

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());

산출:

<?xml version="1.0" encoding="utf-16"?>
<MyClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <MyString><![CDATA[<test>Hello World</test>]]></MyString>
</MyClass>

John Saunders가 게시 한 방법 외에도 XmlCDataSection 을 형식으로 직접 사용할 수 있지만 거의 동일한 내용으로 요약됩니다.

private string _message;
[XmlElement("CDataElement")]
public XmlCDataSection Message
{  
    get 
    { 
        XmlDocument doc = new XmlDocument();
        return doc.CreateCDataSection( _message);
    }
    set
    {
        _message = value.Value;
    }
}

직렬화 할 클래스에서 :

public CData Content { get; set; }

그리고 CData 클래스 :

public class CData : IXmlSerializable
{
    private string _value;

    /// <summary>
    /// Allow direct assignment from string:
    /// CData cdata = "abc";
    /// </summary>
    /// <param name="value"></param>
    /// <returns></returns>
    public static implicit operator CData(string value)
    {
        return new CData(value);
    }

    /// <summary>
    /// Allow direct assigment to string
    /// string str = cdata;
    /// </summary>
    /// <param name="cdata"></param>
    /// <returns></returns>
    public static implicit operator string(CData cdata)
    {
        return cdata._value;
    }

    public CData() : this(string.Empty)
    {
    }

    public CData(string value)
    {
        _value = value;
    }

    public override string ToString()
    {
        return _value;
    }

    public System.Xml.Schema.XmlSchema GetSchema()
    {
        return null;
    }

    public void ReadXml(System.Xml.XmlReader reader)
    {
        _value = reader.ReadElementString();
    }

    public void WriteXml(System.Xml.XmlWriter writer)
    {
        writer.WriteCData(_value);
    }
}

제 경우에는 혼합 필드를 사용하고 있으며 일부 CDATA는 그렇지 않습니다. 적어도 다음 솔루션이 작동합니다 ....

항상 Value 필드를 읽으면 CDATA이든 일반 텍스트이든 상관없이 내용을 얻습니다.

    [XmlElement("")]
    public XmlCDataSection CDataValue {
        get {
            return new XmlDocument().CreateCDataSection(this.Value);
        }
        set {
            this.Value = value.Value;
        }
    }

    [XmlText]
    public string Value;

안하는 것보다 늦게하는 것이 낫다.

건배

이 구현에는 인코딩중인 문자열 내에서 중첩 된 CDATA를 처리 할 수있는 기능이 있습니다 (John Saunders 원래 답변을 기반으로 함).

For example, suppose you wanted to encode the following literal string into CDATA:

I am purposefully putting some <![CDATA[ cdata markers right ]]> in here!!

You would want the resultant output to look something like this:

<![CDATA[I am purposefully putting some <![CDATA[ cdata markers right ]]]]><![CDATA[> in here!!]]>

The following implementation will loop over the string, split up instances of ...]]>... into ...]] and >... and create separate CDATA sections for each.

[XmlRoot("root")]

                        String.Format(

I had a similar need but required a different output format - I wanted an attribute on the node that contains the CDATA. I took some inspiration from the above solutions to create my own. Maybe it will help someone in the future...

public class EmbedScript
{
    [XmlAttribute("type")]
    public string Type { get; set; }

    [XmlText]
    public XmlNode[] Script { get; set; }

    public EmbedScript(string type, string script)
    {
        Type = type;
        Script = new XmlNode[] { new XmlDocument().CreateCDataSection(script) };
    }

    public EmbedScript()
    {

    }
}

In the parent object to be serialised, I have the following property:

    [XmlArray("embedScripts")]
    [XmlArrayItem("embedScript")]
    public List<EmbedScript> EmbedScripts { get; set; }

I get the following output:

<embedScripts>
    <embedScript type="Desktop Iframe">
        <![CDATA[<div id="play_game"><iframe height="100%" src="http://www.myurl.com" width="100%"></iframe></div>]]>
    </embedScript>
    <embedScript type="JavaScript">
        <![CDATA[]]>
    </embedScript>
</embedScripts>
