c# - Serialize string property as attribute, even if string is empty -

public class hat {     [xmltextattribute]     public string name { get; set; }     [xmlattribute("color")]     public string color { get; set; } }  var hat1 = new hat {name="cool hat", color="red"}; var hat2 = new hat {name="funky hat", color=null}; 

this (notice missing color-attribute on funky hat):

<hats>  <hat color="red">cool hat</hat>  <hat>funky hat</hat> </hats> 

this want:

<hats>  <hat color="red">cool hat</hat>  <hat color="">funky hat</hat> </hats> 

how can force serializer create empty attribute in stead of leaving out?

edit:

turns out idiot , created example contained error, because wanted simplify code example.

if value of color "" (or string.empty), serialized empty attribute. however, had null value, not empty string - hence left out.

so behavior wanted behavior of example created.

sorry, guys!

try using list<hat> container. using this:

var hats = new list<hat>     {         new hat { name = "cool hat", color = "red" },          new hat { name = "funky hat", color = string.empty }     };  using (var stream = new filestream("test.txt", filemode.truncate)) {     var serializer = new xmlserializer(typeof(list<hat>));     serializer.serialize(stream, hats); } 

i this:

<?xml version="1.0"?> <arrayofhat xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema">   <hat color="red">cool hat</hat>   <hat color="">funky hat</hat> </arrayofhat>
