    I use this helper:

    public static class ObjectToDictionaryHelper
{
    public static IDictionary ToDictionary(this object source)
    {
        return source.ToDictionary();
    }

    public static IDictionary ToDictionary(this object source)
    {
        if (source == null)
            ThrowExceptionWhenSourceArgumentIsNull();

        var dictionary = new Dictionary();
        foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(source))
            AddPropertyToDictionary(property, source, dictionary);
        return dictionary;
    }

    private static void AddPropertyToDictionary(PropertyDescriptor property, object source, Dictionary dictionary)
    {
        object value = property.GetValue(source);
        if (IsOfType(value))
            dictionary.Add(property.Name, (T)value);
    }

    private static bool IsOfType(object value)
    {
        return value is T;
    }

    private static void ThrowExceptionWhenSourceArgumentIsNull()
    {
        throw new ArgumentNullException("source", "Unable to convert object to a dictionary. The source object is null.");
    }
}



    the usage is just to call .ToDictionary() on an object
    


    Hope it helps.
