There is some code in the following link to get the display text.

Re: How to get label text for each feature in vb.net
http://forums.arcgis.com/threads/61714-how-to-get-label-text-for-each-feature-in-vb.net

This seems like a lot of work to get a label for a the selected feature.
Is this really the only way to do it.

I looked through the samples looking for a C# equivalent of this sample.

What I actually need is some code that allows me to programmatically get

the Display->displayExpression
[[ATTACH=CONFIG]31642[/ATTACH]

This display could be simple text or an expression.

or Labels -> Text String->
[[ATTACH=CONFIG]31643[/ATTACH]

Rickey,

The VBA code shows you how to extract the display expression for every feature in the layer and prints it to debug window. You can easily adapt this to c#

Public Sub PrintDisplayExpressions()
    ' Get layer, assumed first in TOC and has a display expression set
    Dim pMXD As IMxDocument
    Set pMXD = ThisDocument
    Dim pMap As IMap
    Set pMap = pMXD.FocusMap
    Dim pLayer As ILayer
    Set pLayer = pMap.Layer(0)
    Dim pFeaturelayer As IFeatureLayer
    Set pFeaturelayer = pLayer
    Dim pDisplayString As IDisplayString
    Set pDisplayString = pFeaturelayer
    
    ' Print display string
    Dim pFeatureCursor As IFeatureCursor
    Set pFeatureCursor = pFeaturelayer.Search(Nothing, True)
    Dim pFeature As IFeature
    Set pFeature = pFeatureCursor.NextFeature
    Do While Not pFeature Is Nothing
        Debug.Print pDisplayString.FindDisplayString(pFeature)
        Set pFeature = pFeatureCursor.NextFeature
    Loop
End Sub
