Question

我正在使用ms图，以便将文件上传到文档库中。我已经为大型文件实现了代码，并且可以正常工作但我不知道如何设置“驱动器”的自定义列

这是我的代码。我玩过extraData，但没有成功。

任何想法？

谢谢

     public static async Task<DriveItem> uploadFile()
            {
                Stream fileStream = new FileStream(@"C:\prueba\prueba2.xlsx", FileMode.Open);
                DriveItem uploadedFile = null;
                UploadSession uploadSession = null;

    uploadSession = await objGraphServiceClient.Sites["SITE_ID"].Lists["LIST-ID"].Drive.Root.ItemWithPath("EISE_PRUEBA2.xlsx").CreateUploadSession().Request().PostAsync();

 if (uploadSession != null)
            {
                // Chunk size must be divisible by 320KiB, our chunk size will be slightly more than 1MB 
                int maxSizeChunk = (320 * 1024 * 10) * 4;
                ChunkedUploadProvider uploadProvider = new ChunkedUploadProvider(uploadSession, objGraphServiceClient, fileStream, maxSizeChunk);
                var chunkRequests = uploadProvider.GetUploadChunkRequests();
                var exceptions = new List<Exception>();
                var readBuffer = new byte[maxSizeChunk];

                foreach (var request in chunkRequests)
                {


                       var result = await uploadProvider.GetChunkRequestResponseAsync(request, readBuffer, exceptions);



                    if (result.UploadSucceeded)
                    {
                        uploadedFile = result.ItemResponse;

                        var uno = uploadedFile.AdditionalData;

                        var add = new Dictionary<string, object>();

                        add.Add("PositionCode", "Pos-01-" + DateTime.Now.ToString("mmmm"));
                        add.Add("Category", "Category_" + DateTime.Now.ToString("mmmm"));

                        var temp = new ListItem();
                        temp.Id = uploadedFile.Id;
                        temp.Fields = new FieldValueSet();
                        temp.Fields.AdditionalData = add;


                        var driveItem = new DriveItem();

                        //var users = await objGraphServiceClient.Users.Request().GetAsync();

                        //    var driveItem = new DriveItem
                        //    {
                        //        Name = "new-file-name.xlsx"

                        //    };
                        //    //driveItem.CreatedByUser = users.First();
                        //    driveItem.AdditionalData =  new Dictionary<string, object>();

                        //    driveItem.AdditionalData.Add(new KeyValuePair<string, object>("@odata.category", "Category" + DateTime.Now.ToString("mmmm")));
                        //    driveItem.AdditionalData.Add(new KeyValuePair<string, object>("@odata.PositionCode", "Pos-01-" + DateTime.Now.ToString("mmmm")));


                        // var updatedItem = await objGraphServiceClient.Sites["hispaniaassetmanagement.sharepoint.com,d04053f4-eb19-4ed8-9785-0f7aa2a908c8,6227bfe6-c7cb-4990-8f51-0a7fd8c28c1b"].Lists["67987e61-86cc-4f3e-93f2-0b6699b97a94"].Drive.Items[uploadedFile.Id].Request().UpdateAsync(driveItem);

                    }
                }
            }
            return (uploadedFile);
        }

我在SDK中使用其余的API找到了解决方案。使用图资源管理器将是：

匹配：https://graph.microsoft.com/v1.0/sites/ {siteID} / lists / {ListId} / items / {ItemId} / fields

内容类型：application / json

{ “ customColumn”：“值” }

但是！！！如果您要更新返回驱动器项的上载文件的文件，解决方案将是

 var result = await uploadProvider.GetChunkRequestResponseAsync(request, readBuffer, exceptions);

                if (result.UploadSucceeded)
                {
                    uploadedFile = result.ItemResponse;

                    string webApiUrl = "https://graph.microsoft.com/v1.0/sites/"+ siteIDDMS + "/drives/"+driveIDHAMSLib+"/items/"+uploadedFile.Id+"/listItem/fields";

                    JObject paramsJson = new JObject()
                    {
                        ["Category"] = "NewCat_" + DateTime.Now.ToString("mmmm")                            
                    };

                    await RunRestApi(webApiUrl, accessToken, paramsJson,"PATCH", Display);

                }

顺便说一句...有人知道使用SDK能否实现？
