// See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();

// Use your previously obtained access token here:
// See the following examples for getting an access token:
//    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
//    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
//    Refresh Access Token (Azure AD v2.0 Endpoint).
//    Refresh Access Token (Azure AD Endpoint).

// (Make sure your token was obtained with the Files.ReadWrite scope.)
http.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN";

// To delete a file or folder, send a DELETE request like this:
// If not using "me", then the URL path should be /v1.0/users/{id | userPrincipalName}/...
// DELETE /v1.0/me/drive/root:/{item-path}

http.SetUrlVar("item_path","someFolder/sample.pdf");
string resp = await http.QuickDeleteStrAsync("https://graph.microsoft.com/v1.0/me/drive/root:/{$item_path}");
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// A 204 response (with no response body) indicates success.
if (http.LastStatus == 204) {
    Debug.WriteLine("DriveItem deleted.");
}
else {
    Debug.WriteLine("DriveItem not deleted.");
