[Mono-list] XmlSerializer with Dictionary

[Colin JN Breame]

Hello,

When I try to xml serialise a generic dictionary (e.g. 
Dictionary<string,string>), I get the exception:

System.InvalidOperationException: You must implement a default accessor on 
System.Collections.Generic.Dictionary`2[snip] because it inherits from 
ICollection

This looks like it could be a bug but then again I'm not even sure it is 
possible to serialise a generic dictionary.  Any pointers would be 
appreciated.

Cheers,
Colin


test program:

using System.Collections.Generic;
using System.IO;
using System.Xml.Serialization;

public class main_t {
  public static void Main() {
    Dictionary<string, string> test = new Dictionary<string, string>();
    StreamWriter writer = new StreamWriter("output");

    XmlSerializer serialiser = new XmlSerializer(typeof(Dictionary<string,
                                                        string>));
    serialiser.Serialize(writer, test);
  }
}
