【解決方法】Amazon s3 バケットにファイルを追加/アップロードできない

[ad_1]

File.WriteAllBytes("D:/" + model.FileBase.FileName, model.FileBase.Data);
               byte[] bytes = Convert.FromBase64String(model.file);
               using (var inputStream = new MemoryStream(model.FileBase.Data))
               {
                   inputStream.Position = 0;
                   await s3Client.PutObjectAsync(new PutObjectRequest
                   {
                       InputStream = inputStream,
                       ContentType = MimeMapping.GetMimeMapping(model.fileName + model.fileExtension),
                       BucketName = model.bucketName,
                       Key = model.fileName,
                       FilePath = model.destination,
                       CannedACL = S3CannedACL.BucketOwnerFullControl
                   });
               }

私が試したこと：

ファイルを D ドライブに保存できますが、s3 バケットへの投稿中にエラーが表示されます

Please specify one of either an InputStream or a FilePath to be PUT as an S3 object.'
