public static class ObjectExt
{
     public static void CopyTo(this T1 obj, ref T2 otherObject)
            where T1 : class
            where T2 : class
        {
            PropertyInfo[] destFields = otherObject.GetType().GetProperties(
                BindingFlags.Instance | BindingFlags.Public | BindingFlags.GetProperty);

            PropertyInfo[] srcFields = obj.GetType().GetProperties(
                BindingFlags.Instance | BindingFlags.Public | BindingFlags.SetProperty);

            foreach (var property in srcFields)
            {
                var dest = destFields.FirstOrDefault(x => x.Name == property.Name);
                if (dest != null && dest.CanWrite)
                    dest.SetValue(otherObject, property.GetValue(obj, null), null);
            }
        }
}
