Creating Valid ZIP Archives of Multiple Files in C# / .Net

Are .zip files ever going away? I remember back in the 90’s using WinZip as an alternative to the PKZip command line option. Anyway, fast forward 20+ years, and ZIP is still common and a great way to package files. Long story short: AWS Elastic Beanstalk allows you to easily deploy apps using a .zip file (if you haven’t tried Elastic Beanstalk – it’s pretty awesome) and I wanted a faster way to create a .zip of an app. (Yes, I know it’s not the best way to deploy like Git or the API).

There is a bunch of great sample code out there for creating ZIP archives in c# .Net using the ZipArchive Class in System.IO.Compression, but nothing seems to be a complete sample, showing multiple files. Below is what I’ve been using. One difference in this is changing the path separators from backslashes to forward-slashes. Without this, AWS wasn’t able to extract my .zip archive. I would see errors such as: Continue reading “Creating Valid ZIP Archives of Multiple Files in C# / .Net”

Using Amazon Polly from .net / c#, Get MP3 File

knight-rider-car-kittIf you haven’t checked out Amazon’s new Polly (Text-to-Speech (TTS) cloud service) it does produce some pretty great, life-like audio. Below is a quick sample on how you can feed some text to Polly, and get an MP3 file with it. I don’t cover all of the install options of the AWS Toolkit for Visual Studio / .Net, but it’s pretty simple. (listen to this text here)

Below is some code:

AmazonPollyClient pc = new AmazonPollyClient();

SynthesizeSpeechRequest sreq = new SynthesizeSpeechRequest();
sreq.Text = "Your Sample Text Here";
sreq.OutputFormat = OutputFormat.Mp3;
sreq.VoiceId = VoiceId.Amy;
SynthesizeSpeechResponse sres = pc.SynthesizeSpeech(sreq);

using (var fileStream = File.Create(@"c:\yourfile.mp3"))
{
sres.AudioStream.CopyTo(fileStream);
fileStream.Flush();
fileStream.Close();
}

 

Also make sure you have the below included:

using Amazon.Polly;
using Amazon.Polly.Model;

And these 2 NuGet packages added to your project:

aws-polly

This only scratches the surface of what Polly can do. Between streaming, SSML, Lexicons and more at a great price, I think we’ll be seeing more applications use this.
