Pdf is not viewable, showing only loading/activity indicator

[Richy]

I'm retrieving files using azure blob storage and the following is the code, pdf is not viewable only showing loading indicator, other files are viewable but not pdf.

   

protected string DocumentPath { get; set; }

        private async Task GetDocumentDetails(string filename)

        {

            try

            {

                if (containerClient is null)

                    return;

                IsLoading = true;

                if (!string.IsNullOrEmpty(filename))

                {

                    // Get a reference to a blob

                    BlobClient blobClient = containerClient.GetBlobClient(filename);

                    if (blobClient is null)

                        return;

                    // Download the blob's contents and save it to a file

                    BlobDownloadInfo downloadInfo = await blobClient.DownloadAsync();

                    using MemoryStream memoryStream = new MemoryStream();

                    await downloadInfo.Content.CopyToAsync(memoryStream);

                    memoryStream.Position = 0;

                    if(downloadInfo?.ContentType == "application/pdf")

                    {

                        DocumentType = "pdf";

                        DocumentPath = "data:application/pdf;base64," + Convert.ToBase64String(memoryStream.ToArray());

                    }

                     else if (downloadInfo?.ContentType == "application/msword")

                    {

                        DocumentType = "doc";

                        WordDocument document = WordDocument.Load(memoryStream, ImportFormatType.Docx);

                        DocxString = JsonConvert.SerializeObject(document);

                        document.Dispose();

                        DocumentEditorModule editor = docContainer.GetDocumentEditor();

                        await editor.Open(DocxString);

                    }

                    else if (downloadInfo?.ContentType == "image/jpeg")

                    {

                        DocumentType = "image";

                        DocumentPath = "data:image/jpeg;base64," + Convert.ToBase64String(memoryStream.ToArray());

                    }

                    memoryStream.Dispose();

                }

                StateHasChanged();

            }

using Azure.Storage.Blobs as this is currently recommended by Microsoft, and older nugets (Microsoft.Azure.Storage.Blob)are deprecated.
