Required libraries

Reddit.NET

Overview

Retrieves all of today's posts from r/worldnews. This is a simple demonstration of how pagination works.

Library Installation

In the NuGet Package Manager console:

Install-Package Reddit

The Code

using Reddit;
using Reddit.Controllers;
using System;
using System.Collections.Generic;

...

var reddit = new RedditClient("YourRedditAppID", "YourBotUserRefreshToken");

// Since we only need the posts, there's no need to call .About() on this one.  --Kris
var worldnews = reddit.Subreddit("worldnews");

// Just keep going until we hit a post from before today.  Note that the API may sometimes return posts slightly out of order.  --Kris
var posts = new List<Post>();
string after = "";
DateTime start = DateTime.Now;
DateTime today = DateTime.Today;
bool outdated = false;
do
{
	foreach (Post post in worldnews.Posts.GetNew(after: after))
	{
		if (post.Created >= today)
		{
			posts.Add(post);
		}
		else
		{
			outdated = true;
			break;
		}
		
		after = post.Fullname;
	}
} while (!outdated 
	&& start.AddMinutes(5) > DateTime.Now
	&& worldnews.Posts.New.Count > 0);  // This is automatically populated with the results of the last GetNew call.  --Kris
