Network Programming in .NET

This is probably the start of a much larger project, but starting today, I launched TweetJS.com which is a browser-based Javascript library, that lets you display tweets on your website. No authentication needed.

Currently, it has two methods, ListTweetsOnUserTimeline and Search, where TweetJs.ListTweetsOnUserTimeline takes two parameters, the username, and a callback function. It will return data on tweets posted by a given user. and TweetJs.Search takes two parameters, the search query, and a callback function. It will return data on tweets that contain the search query.

They are called like this

TweetJs.ListTweetsOnUserTimeline("PetrucciMusic",
function (data) {
    console.log(data);
});

Under the hood, this makes an ajax call back to our server, which then makes the call to Twitter, using our authentication keys.

Since Tweetsharp is no longer being maintained, there is a fork called tweetmoasharp that is actively maintained. It is pretty much a drop-in replacement for Tweetsharp, with minor differences.

Here’s some code that I wrote to retrieve the tweets from a given user’s timeline

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

var service = new TwitterService(_consumerKey, _consumerSecret);
service.AuthenticateWith(_accessToken, _accessTokenSecret);

var xt = service.ListTweetsOnUserTimeline(new ListTweetsOnUserTimelineOptions() { ScreenName = “PetrucciMusic” });
var strJson = service.Response.Response;

This returns tweets from the account https://twitter.com/PetrucciMusic

The TLS1.2 setting may not be needed, depending on what version of .NET you are using, but I was using an old version, which needed it.
