'  The following comments apply to SharePoint Windows classic authentication.
'  -------------------------------------------------------------------------
'  For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
'  The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
'  The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
'  Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
'  for example, "chilkat" instead of "chilkat@mycompany.com"

Dim http As New Chilkat.Http

'  If SharePoint Windows classic authentication is used, then set the
'  Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = "SHAREPOINT_USERNAME"
http.Password = "SHAREPOINT_PASSWORD"
http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN"
http.NtlmAuth = True

'  -------------------------------------------------------------------------
'  The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
'  If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
'  establish the cookie as shown at SharePoint Online Authentication
'  -------------------------------------------------------------------------

'  Indicate that we want a JSON reply
http.Accept = "application/json;odata=verbose"

'  The contents of a SharePoint list can be downloaded by it's URI,
'  which has the following URL format:
'  https://xyzoffice.mycompany.com/_api/Web/Lists(guid'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx')/items
' 
'  To get the URI's for all SharePoint lists,
'  See Get SharePoint Lists.

'  Download the list like this (where the SHAREPOINT_DOCUMENTS_GUID is replaced with the actual GUID)
Dim sbJson As New Chilkat.StringBuilder
Dim success As Boolean = Await http.QuickGetSbAsync("https://SHAREPOINT_HTTPS_DOMAIN/_api/Web/Lists(guid'SHAREPOINT_DOCUMENTS_GUID')/items",sbJson)
If (success <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


Dim json As New Chilkat.JsonObject
json.LoadSb(sbJson)
json.EmitCompact = False


'  Iterate over the items in this list.
Dim numItems As Integer = json.SizeOfArray("d.results")
Debug.WriteLine("Number of Items in this SharePoint List = " & numItems)

Dim i As Integer = 0
While i < numItems
    json.I = i

    Dim title As String = json.StringOf("d.results[i].Title")
    Dim uri As String = json.StringOf("d.results[i].__metadata.uri")

    Debug.WriteLine((i + 1) & ": " & title)
    '  This is the URI for the Nth item in this list
    Debug.WriteLine("URI: " & uri)

    i = i + 1
End While


'  My output when testing is like what is shown below.

'  I found that not every item has a Title,  but as viewed in a browser, I can see each of the item's name.
'  (The number of items agrees with what I can interactively see in a browser.) The mystery of what
'  is being shown for the name (or title) in the browser will be investigated further as Chilkat
'  continues to explore the SharePoint API...
