    }

    public override Type BindToType(string assemblyName, string typeName)
    {
        Type typeToDeserialize = null;
        if (!assemblyName.Contains("System") && !assemblyName.Contains("mscorlib"))

        }
        typeToDeserialize = Type.GetType(String.Format("{0}, {1}",
            typeName, assemblyName));
        return typeToDeserialize;
    }
