There is a multi-level dictionary Dictionary <string, object>, where the value again can be the multi-level dictionary Dictionary <string, object>. How can I convert it to XML?
On the Internet , the class SerializableDictionary was found , but it works only with single-level dictionaries:
using System.Collections.Generic; using System.Xml.Serialization; public class SerializableDictionary<TKey, TValue> : Dictionary<TKey, TValue>, IXmlSerializable { public System.Xml.Schema.XmlSchema GetSchema() { return null; } public void ReadXml(System.Xml.XmlReader reader) { XmlSerializer keySerializer = new XmlSerializer(typeof(TKey)); XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue)); bool wasEmpty = reader.IsEmptyElement; reader.Read(); if (wasEmpty) return; while (reader.NodeType != System.Xml.XmlNodeType.EndElement) { reader.ReadStartElement("item"); reader.ReadStartElement("key"); TKey key = (TKey)keySerializer.Deserialize(reader); reader.ReadEndElement(); reader.ReadStartElement("value"); TValue value = (TValue)valueSerializer.Deserialize(reader); reader.ReadEndElement(); this.Add(key, value); reader.ReadEndElement(); reader.MoveToContent(); } reader.ReadEndElement(); } public void WriteXml(System.Xml.XmlWriter writer) { XmlSerializer keySerializer = new XmlSerializer(typeof(TKey)); XmlSerializer valueSerializer = new XmlSerializer(typeof(TValue)); foreach (TKey key in this.Keys) { writer.WriteStartElement("item"); writer.WriteStartElement("key"); keySerializer.Serialize(writer, key); writer.WriteEndElement(); writer.WriteStartElement("value"); TValue value = this[key]; valueSerializer.Serialize(writer, value); writer.WriteEndElement(); writer.WriteEndElement(); } } } public static string Serialize(SerializableDictionary<string, object> data) { using(StringWriter sw = new StringWriter()) { XmlSerializer ser = new XmlSerializer(typeof(SerializableDictionary<string, object>)); ser.Serialize(sw, data); return sw.ToString(); } } Serialize(new SerializableDictionary<string, object>() { { "Node 1", "Node 1 value" }, { "Node 2", true }, { "Node 3", 5} }); //<?xml version="1.0" encoding="utf-16"?> //<dictionary> // <item> // <key> // <string>Node 1</string> // </key> // <value> // <anyType xmlns:q1="http://www.w3.org/2001/XMLSchema" d4p1:type="q1:string" xmlns:d4p1="http://www.w3.org/2001/XMLSchema-instance">Node 1 value</anyType> // </value> // </item> // <item> // <key> // <string>Node 2</string> // </key> // <value> // <anyType xmlns:q1="http://www.w3.org/2001/XMLSchema" d4p1:type="q1:boolean" xmlns:d4p1="http://www.w3.org/2001/XMLSchema-instance">true</anyType> // </value> // </item> // <item> // <key> // <string>Node 3</string> // </key> // <value> // <anyType xmlns:q1="http://www.w3.org/2001/XMLSchema" d4p1:type="q1:int" xmlns:d4p1="http://www.w3.org/2001/XMLSchema-instance">5</anyType> // </value> // </item> //</dictionary> Serialize(new SerializableDictionary<string, object>() { { "Node 1", "Node 1 value" }, { "Node 2", true }, { "Node 3", new int[]{1,2,3}} }); // System.InvalidOperationException: The type System.Int32[] may not be used in this context. // System.InvalidOperationException: There was an error generating the XML document. // method WriteXml valueSerializer.Serialize(writer, value); Ideally, I would like to have an XML structure, where the node name corresponds to the element name. For example:
<?xml version="1.0" encoding="utf-16"?> <Node1>Node 1 value</Node1> <Node2>true</Node2> <Node3> <Item>1</Item> <Item>2</Item> <Item>3</Item> </Node3> You can play with the code here .
