Description Seth Rosetter 2015-06-10 17:42:02 UTC
The program below throws the following exception on .Net 4.5
"An unhandled exception of type 'System.Runtime.Serialization.SerializationException' occurred in System.Runtime.Serialization.dll

Additional information: Type 'System.String[]' with data contract name 'ArrayOfstring:http://schemas.microsoft.com/2003/10/Serialization/Arrays' is not expected. Consider using a DataContractResolver if you are using DataContractSerializer or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to the serializer."

On Mono 4.0, the serialization completes with no exception thrown.

class Program
{
	static void Main (string[] args)
	{
		var test = new Dictionary<string, object> ();
		test.Add ("test", new string[] { "a", "b", "c" });

		var stream = new MemoryStream ();
		var writer = XmlDictionaryWriter.CreateBinaryWriter (stream);
		var dcs = new DataContractSerializer (typeof(Dictionary<string, object>));
		dcs.WriteObject(writer, test);
	}
}
