Downloads a particular SharePoint list and parses the JSON.

//  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"

Chilkat.Http http = 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

//  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)
Chilkat.StringBuilder sbJson = new Chilkat.StringBuilder();
bool success = await http.QuickGetSbAsync("https://SHAREPOINT_HTTPS_DOMAIN/_api/Web/Lists(guid'SHAREPOINT_DOCUMENTS_GUID')/items",sbJson);
if (success != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

Chilkat.JsonObject json = new Chilkat.JsonObject();
json.LoadSb(sbJson);
json.EmitCompact = false;

//  Iterate over the items in this list.
int numItems = json.SizeOfArray("d.results");
Debug.WriteLine("Number of Items in this SharePoint List = " + Convert.ToString(numItems));

int i = 0;
while (i < numItems) {
    json.I = i;

    string title = json.StringOf("d.results[i].Title");
    string uri = json.StringOf("d.results[i].__metadata.uri");

//  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...
