Question

使用 Microsoft Graph 的 .NET SDK，您可以上传（小）文件。示例 .

如何使用 .NET SDK 上传大文件（> 4MB）？

也就是说，SDK可以用来实现"Upload large files with an upload session"吗？

Answer 1

这将在下一个版本的 .NET Microsoft Graph 客户端库中提供。它的工作方式与 .NET OneDrive 客户端库中的功能相同。您可以在我的工作 branch 中查看此内容。您可以在回购中提供反馈。

Answer 2

这是我最近使用 Microsoft Graph .Net SDK 编写的代码。需要 GraphServiceClient(graphClient) 身份验证。

    if (fileSize.MegaBytes > 4)
                    {
                        var session = await graphClient.Drive.Root.ItemWithPath(uploadPath).CreateUploadSession().Request().PostAsync();
                        var maxSizeChunk = 320 * 4 * 1024;
                        var provider = new ChunkedUploadProvider(session, graphClient, stream, maxSizeChunk);
                        var chunckRequests = provider.GetUploadChunkRequests();
                        var exceptions = new List<Exception>();
                        var readBuffer = new byte[maxSizeChunk];
                        DriveItem itemResult = null;
                        //upload the chunks
                        foreach (var request in chunckRequests)
                        {
                            // Do your updates here: update progress bar, etc.
                            // ...
                            // Send chunk request
                            var result = await provider.GetChunkRequestResponseAsync(request, readBuffer, exceptions);

                            if (result.UploadSucceeded)
                            {
                                itemResult = result.ItemResponse;
                            }
                        }

                        // Check that upload succeeded
                        if (itemResult == null)
                        {
                            await UploadFilesToOneDrive(fileName, filePath, graphClient);
                        }
                    }
                    else
                    {
                        await graphClient.Drive.Root.ItemWithPath(uploadPath).Content.Request().PutAsync<DriveItem>(stream);
                    }
