Getting Baseline Label information MKSIssueLabels using C# API

Using the C# api ....I can use viewissue in the mksapiviewer and it shows that label information is available. However when I parse through the Workitems ....and then the fields I get to the field named  

MKSIssueLabels now I am unsure how to get to the mksItemList items

foreach (WorkItem w in r.WorkItems) 

{

foreach (IField f in w.Fields.Values)

{

if (f.Name == "MKSIssueLabels")

{

// Parse through the items in mksItemList ??

}

}

}

Can someone point out how to do this?
