Question

I’m serializing to XML my class where one of properties has type List<string>.

public class MyClass {     ...     public List<string> Properties { get; set; }     ... } 

XML created by serializing this class looks like this:

<MyClass>     ...     <Properties>         <string>somethinghere</string>         <string>somethinghere</string>     </Properties>     ... </MyClass> 

and now my question. How can I change my class to achieve XML like this:

<MyClass>     ...     <Properties>         <Property>somethinghere</Property>         <Property>somethinghere</Property>     </Properties>     ... </MyClass> 

after serializing. Thanks for any help!

Try XmlArrayItemAttribute:

using System; using System.IO; using System.Xml.Serialization; using System.Collections.Generic;  public class Program {     [XmlArrayItem('Property')]     public List<string> Properties = new List<string>();      public static void Main(string[] args)     {         Program program = new Program();         program.Properties.Add('test1');         program.Properties.Add('test2');         program.Properties.Add('test3');          XmlSerializer xser = new XmlSerializer(typeof(Program));         xser.Serialize(new FileStream('test.xml', FileMode.Create), program);     } } 

test.xml:

<?xml version='1.0'?> <Program xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema'>   <Properties>     <Property>test1</Property>     <Property>test2</Property>     <Property>test3</Property>   </Properties> </Program>
