How does it works?

To begin with, please go to the Twitter Developer Portal and create a new application
Then you must instantiate a new client:

var client = new TwitterSharp.Client.TwitterClient(bearerToken);

From there you can access various methods to access tweets and users, however please make note that a basic request only includes:

• For tweets: its ID and content
• For users: its ID, name and username

To solve that, most function take an array of UserOption or TweetOption, make sure to add what you need there!

Need more help? You can use the examples below, if you're still lost feel free to open an issue or a discussion!

Examples

Get a tweet from its ID

var client = new TwitterSharp.Client.TwitterClient(bearerToken);
var answer = await client.GetTweetAsync("1389189291582967809");
Console.WriteLine(answer.Text); // たのしみ！！\uD83D\uDC93 https://t.co/DgBYVYr9lN

Get an user from its username

var client = new TwitterSharp.Client.TwitterClient(bearerToken);
var answer = await client.GetUserAsync("theindra5");
Console.WriteLine(answer.Id); // 1022468464513089536

Get latest tweets from an user id with the attached medias

var client = new TwitterSharp.Client.TwitterClient(bearerToken);
// You can get the id using GetUsersAsync
var answer = await client.GetTweetsFromUserIdAsync("1109748792721432577", new TweetSearchOptions
{
    TweetOptions = new[] { TweetOption.Attachments },
    MediaOptions = new[] { MediaOption.Preview_Image_Url }
});
for (int i = 0; i < answer.Length; i++)
{
    var tweet = answer[i];
    Console.WriteLine($"Tweet n°{i}");
    Console.WriteLine(tweet.Text);
    if (tweet.Attachments?.Media?.Any() ?? false)
    {
        Console.WriteLine("\nImages:");
        Console.WriteLine(string.Join("\n", tweet.Attachments.Media.Select(x => x.Url)));
    }
    Console.WriteLine("\n");
}

Get the users that someone follow

var client = new TwitterClient(Environment.GetEnvironmentVariable("TWITTER_TOKEN"));

var answer = await client.GetFollowingAsync("1433657158067896325", new UserSearchOptions
{
    Limit = 1000
});
Console.WriteLine(string.Join("\n", answer.Users.Select(u => u.Username)));
while (answer.NextAsync != null) // We go to the next page if there is one
{
    answer = await answer.NextAsync();
    Console.WriteLine(string.Join("\n", answer.Users.Select(u => u.Username)));
}

Continuously get all the new tweets from some users

var client = new TwitterSharp.Client.TwitterClient(bearerToken);

// Subscribe to 5 Twitter accounts
var request = new TwitterSharp.Request.StreamRequest(
    Expression.Author("moricalliope") // using TwitterSharp.Rule;
        .Or(
            Expression.Author("takanashikiara"),
            Expression.Author("ninomaeinanis"),
            Expression.Author("gawrgura"),
            Expression.Author("watsonameliaEN")
        )
, "Hololive");
await client.AddTweetStreamAsync(request); // Add them to the stream

// We display all the subscriptions we have
var subs = await client.GetInfoTweetStreamAsync();
Console.WriteLine("Subscriptions: " + string.Join("\n", subs.Select(x => x.Value.ToString())));

// NextTweetStreamAsync will continue to run in background
Task.Run(async () =>
{
    // Take in parameter a callback called for each new tweet
    // Since we want to get the basic info of the tweet author, we add an empty array of UserOption
    await client.NextTweetStreamAsync((tweet) =>
    {
        Console.WriteLine($"From {tweet.Author.Name}: {tweet.Text} (Rules: {string.Join(',', tweet.MatchingRules.Select(x => x.Tag))})");
    },
    new TweetSearchOptions
    {
        UserOptions = Array.Empty<UserOption>()
    });
});

// Add new high frequent rule after the stream started. No disconnection needed.
await client.AddTweetStreamAsync(new TwitterSharp.Request.StreamRequest( Expression.Author("Every3Minutes"), "Frequent"));

Search the expression tree

var expressionString = "(@twitterdev OR @twitterapi) -@twitter";
// Parse the string into an expression with a typed expression tree
var parsedExpression = Expression.Parse(expressionString);

var mentionsCount = CountExpressionsOfType(parsedExpression, ExpressionType.Mention);
var groupsCount = CountExpressionsOfType(parsedExpression, ExpressionType.And) + CountExpressionsOfType(parsedExpression, ExpressionType.Or);;

Console.WriteLine($"Found {mentionsCount} mentions and {groupsCount} groups in the expression"); // Found 3 mentions and 2 groups in the expression

// Helper function to count recursive
int CountExpressionsOfType(Expression expression, ExpressionType type)
{
    var i = expression.Type == type ? 1 : 0;

    if (expression.Expressions != null)
    {
        i += expression.Expressions.Sum(exp => CountExpressionsOfType(exp, type));
    }

    return i;
}
