To save a PDF file to Azure blob storage, you can follow the steps below

Step 1: Create a simple console application

Step 3: Install the Syncfusion.Pdf.Net.Core and Microsoft.Azure.Storage.Blob NuGet packages as a reference to your project from the NuGet.org.

Step 4: Include the following namespaces in the Program.cs file.

C# [Cross-platform]

using Syncfusion.Pdf;
    using Syncfusion.Pdf.Graphics;
    using Syncfusion.Drawing;
    using Microsoft.Azure.Storage;
    using Microsoft.Azure.Storage.Blob;

Step 5: Add the below code example to create a simple PDF and save in Azure blob storage.

C# [Cross-platform]

// Create a new PDF document
        using (PdfDocument doc = new PdfDocument())
        {
            // Add a page to the document.
            PdfPage page = doc.Pages.Add();
            // Get the graphics object for drawing on the page.
            PdfGraphics graphics = page.Graphics;
            // Create a font to use for drawing text
            PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 12);
            // Draw the text.
            graphics.DrawString("Hello, World!", font, PdfBrushes.Black, new PointF(10, 10));
            // Create a memory stream to save the PDF document.
            MemoryStream stream = new MemoryStream();
            doc.Save(stream);
            // Write the contents of the memory stream to a file named "sample.pdf".
            File.WriteAllBytes("sample.pdf", stream.ToArray());
            // Close the document
            doc.Close(true);
        }
        // Parse the connection string for the Azure Storage Account.
        CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionString);
        // Create a client for accessing Blob storage.
        CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
        // Get a reference to the container name.
        CloudBlobContainer container = blobClient.GetContainerReference(containerName);
        container.CreateIfNotExists();
        // Get a reference to the block blob name.
        CloudBlockBlob blockBlob = container.GetBlockBlobReference(blobName);
        // Open the local file "sample.pdf" for reading
        using (var fileStream = File.OpenRead("sample.pdf"))
        {
            // Upload the contents of the local file to the Azure Blob Storage
            blockBlob.UploadFromStream(fileStream);
        }
