Facebook Graph API

I am tying to get the work information from a facebook user using Graph API
 
When I use the Graph API and get the User object, it contains work information, which is essentially a list of the work history. The list elements contain nodes of employer, location, description, etc...
The FQL return it as a JsonObject, how do i get the the value employer out of it. I am only interested in the last employer. I tried something below but could not get it working.
 
If Not facebook.Session Is Nothing Then
JSuser = DirectCast(facebook.Api("me"), JsonObject)

Dim WorkJSArray As JsonArray = DirectCast(JSuser("work"), JsonArray)

If WorkJSArray.Count > 0 Then
For Each JsonObject In WorkJSArray
Dim uemployer As String = DirectCast(WorkJSArray.Item(0).ToString(), String)
Next
...
