// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

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

// This example will delete the folder /Documents/ChilkatTest2

Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.HttpVerb = "POST";
// If your Sharepoint site is within a site collection, then use "/sites/teamA/_api/web/GetFolderByServerRelativeUrl('/sites/teamA/Documents/ChilkatTest2')" where "teamA" is the name of the site.
req.Path = "/_api/web/GetFolderByServerRelativeUrl('/Documents/ChilkatTest2')";

// We need to add a form digest value in the X-RequestDigest header field.
// See this example for details on
// how to get (and cache) a form digest value
req.AddHeader("X-RequestDigest","SHAREPOINT_FORM_DIGEST");

// Add additional required headers.
req.AddHeader("IF-MATCH","*");
req.AddHeader("X-HTTP-Method","DELETE");

// Send the POST using https (TLS). (Port 443 is the default port for https.)
bool bUseTls = true;
Chilkat.HttpResponse resp = http.SynchronousRequest("SHAREPOINT_HTTPS_DOMAIN",443,bUseTls,req);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// If failed, the response body contains XML 
Chilkat.Xml xml = new Chilkat.Xml();
xml.LoadXml(resp.BodyStr);

// Note: It seems that if an attempt is made to delete a folder that does not exist,
// the response status code is 200, indicating success.
if (resp.StatusCode != 200) {
    Debug.WriteLine("Response status code = " + Convert.ToString(resp.StatusCode));
    Debug.WriteLine(xml.GetXml());
    Debug.WriteLine("Failed");

    return;
}

// If successful, the response body is empty.
Debug.WriteLine("Success.");
