How can I get a layer's DataSource properties.

Question

I have some loaded layers in a map control, and I would like to get some information from these layers.

Do you know what classes/interfaces I need to use in order to get the information that is displayed in a layer properties Source tab. (See attached pic)

Keep in mind, these are ALREADY loaded layers. I'm not attempting nor able to load the layers myself and get the information at that point. (if that makes any difference)

I'm looking for the data for these items* Data Type:
  * Feature Class:
  * SERVER:
  * INSTANCE:
  * Location:
  * AUTHENTICATION_MODE:
  * VERSION:
 
I already have the information for * Feature Type
  * Geometry Type

You can use  pfeatureclass.FeatureDataset if the feature class is stored inside feature dataset. if not use below statement to convert ifeatureclass to idataset and then get the connection properties.

IDataset pdataset = pfeatureclass as IDataset;

many thanks, working now

Well, another option, if the data is published via server, would be to use:

.NET
IPublishLayer.DataDetails  
http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/0012/001200000p29000000.htm

Java
FeatureLayer.getDataDetails()
http://help.arcgis.com/en/sdk/10.0/java_ao_adf/api/arcobjects/com/esri/arcgis/carto/FeatureLayer.html

You get a nicely formatted String with those properties you're looking for.

Data Type: ArcSDE Database
Location: Server: Server Name
User: username
Instance: sde:sqlserver:whatever
Version: dbo.DEFAULT
Description: Instance default version.
Feature Class: server.owner.name

And, as you can see the Java version gets the output wrong.  I reported as a potential bug...
