Collection class can not be XML serialized/deserialized

[Former user]

The collection<T> class seems to be missing the generic Add (Object item) function. Please add the following to the collection<T> class:

 public override void Add(object item)
 {
         if (item is T)
         {
             this.items.Add((T) item);
             this.OnItemAdded((T) item);
         }
 }

Thanks for your report, I will try to add a solution to the next version. Xml Serialization is not supported, but if this method is the only thing that's missing to make it possible, I'll gladly add it :)

I created a unit test for xml serialization today, but it worked as intended.

The test case is below. If you have any other information when the xml serialization fails, please let me know and I will reopen the issue.

namespace Slash.Unity.DataBind.Tests.Core.Data
{
    using System.IO;
    using System.Linq;
    using System.Xml.Serialization;
    using NUnit.Framework;

    public class XmlSerializationTest
    {
        [Test]
        public void SerializeContextWithCollection()
        {
            var context = new ContextWithCollection {StringCollection = new Collection<string> {"a", "c", "b"}};
            TestSerialize(context);
        }

        [Test]
        public void SerializeContextWithProperty()
        {
            var context = new ContextWithProperty {Int = 23};
            TestSerialize(context);
        }

        private static void TestSerialize(object context)
        {
            var stringWriter = new StringWriter();
            var xmlSerializer = new XmlSerializer(context.GetType());
            xmlSerializer.Serialize(stringWriter, context);

            var xml = stringWriter.ToString();
            var deserializedContext = xmlSerializer.Deserialize(new StringReader(xml));

            Assert.AreEqual(context, deserializedContext);
        }
