How to update list item using client object model without changing created/modified dates?

Question

Hello All,
I want to update list item using the SharePoint Client Object
Model without updating the created / modified date. Is it possible?
Please help.
Thanks.

Using the SystemUpdate method should do the trick, according
to its literature.
Additionally, would something like this be of any use for you?  Taken from this
Stack Exchange thread: -
public static class SPListItemExtensions
/// <summary>
/// Provides ability to update list item without firing event receiver.
/// </summary>
/// <param name="item"></param>
/// <param name="doNotFireEvents">Disables firing event receiver while updating item.</param>
public static void Update(this SPListItem item, bool doNotFireEvents)
SPItemEventReceiverHandling rh = new SPItemEventReceiverHandling();
if (doNotFireEvents)
try
rh.DisableEventFiring();
item.Update();
finally
rh.EnableEventFiring();
else
item.Update();
/// <summary>

public static void SystemUpdate(this SPListItem item, bool incrementListItemVersion, bool doNotFireEvents)
SPItemEventReceiverHandling rh = new SPItemEventReceiverHandling();
if (doNotFireEvents)
try
rh.DisableEventFiring();
item.SystemUpdate(incrementListItemVersion);
finally
rh.EnableEventFiring();

item.SystemUpdate(incrementListItemVersion);
