[zipswich]

It is difficult to derive the C# code from the HTTP example.

In addition the update example uses a string type for the stream, which isn't the right-type. Showing loading a file stream or converting the text to the stream as a complete example would be more useful.

Also related to #3902 about setting the proper file type for upload should be part of this sample.

Please add a c#/non-http example for uploading a NEW file with microsoft graph. Not sure why it's been a month and still no documentation is provided

[zipswich]

@angelinatquach in case it is useful and you have not noticed it, here is a working code snippet for both small and large files:

@zipswich your example only seems to reference updating an existing file, since your snippet always requires an item ID
.Items[diameraAlternativeRoll.Id]

I want to upload a NEW file, so I wouldn't know the item id

[zipswich]

@angelinatquach diameraAlternativeRoll.Id is the id of an existing folder where a file will be uploaded.

[angelinatquach]

@zipswich is the existing folder the same thing as a drive?

This is the error I get. However, I use the same driveID to get the files, and I can see them...

Microsoft.Graph.ServiceException: Code: itemNotFound
Message: The resource could not be found.

@angelinatquach No. It is a folder under OneDrive. Here is the code to get it:

     DriveItem diameraAlternativeRoll = null;
     IDriveItemChildrenCollectionPage children = await provider.Graph.Me.Drive.Root.Children
                                    .Request()
                                    .GetAsync();
     diameraAlternativeRoll = children.First(r => r.Name == "Camera Alternative roll");

thank you!!! This worked so good, I really appreciate it @zipswich
