(C# UWP/WinRT) OneDrive -- Create a New Folder

Demonstrates how to create a new folder.

Note: This example requires Chilkat v9.5.0.68 or greater.

// This example requires the Chilkat API to have been previously unlocked.
// 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 create a new folder, send a POST request like this:
// POST /me/drive/items/{parent-item-id}/children

// We first need to get the item-id for the folder where the new folder will be created.
// This example will create a new folder named "abc" within /someFolder,
// so we need the item-id for /someFolder.

// Set the URL var for the next request which will create the new folder.
http.SetUrlVar("parent_item_id",json.StringOf("id"));
