HttpStream 2.0.42

HttpStream

This C# project implements randomly accessible stream on HTTP 1.1 transport. Typically, HttpClient provides almost all HTTP features but it just provides us with a way to download a file completely. The implementation take advantage of HTTP 1.1 range access or on fallback case, it uses HTTP/1.0 sequential download anyway.

NuGet Package

A prebuilt NuGet package is available: Espresso3389.HttpStream.

To install espresso3389.HttpStream, run the following command in the Package Manager Console:

PM> Install-Package Espresso3389.HttpStream

Simple Usage

// cache stream
var fs = File.Create("cache.jpg");

// The third parameter, true indicates that the httpStream will close the cache stream.
var uri = new Uri(@"https://dl.dropboxusercontent.com/u/150906/2007-01-28%2006.04.05.JPG");
var httpStream = new Espresso3389.HttpStream.HttpStream(uri, fs, true);

// RangeDownloaded is called on every incremental download
httpStream.RangeDownloaded += (sender, e) =>
{
  Console.WriteLine("Progress: {0}%", (int)(100 * httpStream.CachedRatio));
};

// The following code actually invokes download whole the file
var bmp = await BitmapFactory.DecodeStreamAsync(httpStream);
