(C#) OneDrive -- Upload Binary Data from Memory

See more OneDrive Examples

Demonstrates how to upload binary data directly from memory to the signed-in user's OneDrive. This uses OneDrive's simple upload API to upload in a single API call, which only supports uploads up to 4MB in size. (See the other example(s) for uploading larger files.)

Note: This example requires Chilkat v9.5.0.97 or greater.

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

// This example uses the OAuth client credentials flow.
// See How to Create an Azure App Registration for OAuth 2.0 Client Credentials

// Use your client ID, client secret, and tenant ID in the following lines
Chilkat.JsonObject json = new Chilkat.JsonObject();
json.UpdateString("client_id","2871da2c-8176-4b7f-869b-2311aa82e743");
