Log changes made to LINQ to SQL generated objects

I was wonder what would be the best way to log changes made to objects created by linq.

I have searched around and this is what i came up with:

using (testDBD开发者_C百科ataContext db = new testDBDataContext())
{
    Sometable table = db.Sometables.Single(x => x.id == 1);

    table.Something = txtTextboxToChangeValue.Text;

    Sometable tableBeforeChanges = db.Sometables.GetOriginalEntityState(table);

    foreach (System.Data.Linq.ModifiedMemberInfo item in db.Sometables.GetModifiedMembers(table))
    {
        // Obviously writing to debug is not what i would like to do
        System.Diagnostics.Debug.WriteLine("Old value: " + item.OriginalValue.ToString());
        System.Diagnostics.Debug.WriteLine("New value: " + item.CurrentValue.ToString());
    }
}

Is this really the way to go to log changes?

Change Tracking or Change Data Capture are the way to go. LINQ has nothing to do with it. As a general rule, client side cannot properly track changes that occur in the server because the changes may occur in alternate access that is not occurring through the client. As a cautionary note, setting up a complete data audit for all changes is seldom successful as the performance tax penalty is usually too high.

Ive searched around and i think im gonna use DoodleAudit (doddleaudit.codeplex.com) it seems to give me what i wanted, tnx for helping anyways!
