string outputFile = Path.Combine("c:\output", "converted.pdf");
using (Converter converter = new Converter(() => DownloadFile(blobName)))
{
PdfConvertOptions options = new PdfConvertOptions();
converter.Convert(outputFile, options);
}
}
public static Stream DownloadFile(string blobName)
{
CloudBlobContainer container = GetContainer();
CloudBlob blob = container.GetBlobReference(blobName);
MemoryStream memoryStream = new MemoryStream();
blob.DownloadToStream(memoryStream);
memoryStream.Position = 0;
return memoryStream;
}
private static CloudBlobContainer GetContainer()
{
string accountName = "***";
string accountKey = "***";
string endpoint = $"https://{accountName}.blob.core.windows.net/";
string containerName = "***";
StorageCredentials storageCredentials = new StorageCredentials(accountName, accountKey);
CloudStorageAccount cloudStorageAccount = new CloudStorageAccount(
storageCredentials, new Uri(endpoint), null, null, null);
CloudBlobClient cloudBlobClient = cloudStorageAccount.CreateCloudBlobClient();
CloudBlobContainer container = cloudBlobClient.GetContainerReference(containerName);
container.CreateIfNotExists();
return container;
}
