Ooops, no, even with SoapFormatter you cannot serialize an IDictionary object,
but now I see that the testcase is using BinaryFormatter. Just for the sake of
simplicity, the code is this:

SortedDictionary<string, int> test = new SortedDictionary<string, int>();

test.Add("dfds", 2323);

FileStream fs = new FileStream("Cache.bin", FileMode.Create, FileAccess.Write,
FileShare.Read);

System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bf = new
System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();

bf.Serialize(fs, test);

fs.Close();


And the error is:


Unhandled Exception: System.Runtime.Serialization.SerializationException: Type
System.Collections.Generic.RBTree is not marked as Serializable.
