Using CoreServiceClient in C#, how do I get the latest published version of an item?

Question

I'm new to Tridion, thanks for your help :-)

I can successfully bind to a service endpoint, validate CoreServiceClient.IsExistingObject("tcm:xx-xxx-xx"), and now I would like to retrieve the version (and other) properties of that item.

How to do this?

Welcome to the wonderful world of Tridion... Get ready to go through this cycle a few times in the coming months.

Here's a couple of examples to achieve some of what you're searching for - but not all. Tridion does not store the information you're searching for in the CM, it's only available in Content Delivery - unless you want to do some date comparisons.

First, the basics - read a Component:

var c = (ComponentData)client.Read("tcm:1-2", new ReadOptions());

Read a Component's Version Info:

FullVersionInfo info = (FullVersionInfo)c.VersionInfo;
int currentVersion = info.LastVersion.GetValueOrDefault();

Finding out publishing information about the object involves asking Tridion for some more advanced system data, which is not directly part of the object. In particular, you will want to look at PublishInfoData:

foreach (PublishInfoData p in _client.GetListPublishInfo("tcm:1-2"))
{
    Console.WriteLine("Item was published at {0} to target {1} rendered with {2}",
                       p.PublishedAt.ToShortDateString(),
                       p.PublicationTarget.Title,
                       p.RenderedWith.Title);
}

Have fun, and come back with more questions.

This will get you the item

CoreServiceClient.Read("tcm:xx-xxx-xx", new ReadOptions())

If you expect a certain item type you can get the item specific data

var page = (PageData) CoreServiceClient.Read("tcm:xx-xxx-xx", new ReadOptions())

Getting the version The version will be something like

var item = CoreServiceClient.Read("tcm:xx-xxx-xx", new ReadOptions());
var version = item.VersionInfo.Version;

Check the Core Service API reference documentation (chm file) and read about the ICoreService2011 Members and IdentifiableObjectData Members to learn more about CoreService operations and other data properties in the item object.
