(C# UWP/WinRT) 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 v9.5.0.68 or greater.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads Chilkat for the Universal Windows Platform (UWP)

// 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";

// First, let's download a PDF from the web directly into memory.  Then upload the PDF
// to OneDrive.
Chilkat.BinData pdfBytes = new Chilkat.BinData();

if (success != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// Upload the PDF to our OneDrive to /someFolder/sample.pdf
Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.HttpVerb = "PUT";
// If not using "me", then the path should be /v1.0/users/{id | userPrincipalName}/...
req.Path = "/v1.0/me/drive/root:/someFolder/sample.pdf:/content";
req.LoadBodyFromBd(pdfBytes);
// If you're uploading a file and don't know what the Content-Type should be,
// just use "application/octet-stream".  
req.ContentType = "application/pdf";

Chilkat.HttpResponse resp = await http.SynchronousRequestAsync("graph.microsoft.com",443,true,req);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;

// If successful, a 201 status code is returned, with the driveItem object in the response body for the newly created file.
Chilkat.JsonObject json = new Chilkat.JsonObject();
json.EmitCompact = false;
json.Load(resp.BodyStr);

if (resp.StatusCode != 201) {
    Debug.WriteLine(json.Emit());
    Debug.WriteLine("Response status = " + Convert.ToString(resp.StatusCode));
