Discord Bot Time in C#

Introduction

In this tutorial, we will create a Discord Bot in C# that will display the current time in a specific timezone. We will be using the Discord.Net library to handle interactions with the Discord API, and the TimeZoneInfo class from the System library to get the current time in the specified timezone.

Prerequisites

To follow this tutorial, you will need:

• A Discord account
• A Discord server where you have the privileges to add bots
• Visual Studio or any other C# code editor

Step 1: Creating a Discord Bot

First, we need to create a Discord Bot and add it to our server. To do this, follow these steps:

1. Go to the Discord Developer Portal and click "New Application".
2. Enter a name for your bot and click "Create".
3. Go to the "Bot" tab and click "Add Bot".
4. Once the bot is created, copy its token and keep it somewhere safe.

Step 2: Setting up the Project

Create a new C# Console Application project in Visual Studio. Then, add the Discord.Net and Newtonsoft.Json libraries to your project using NuGet packages.

using Discord;
using Discord.Commands;
using Newtonsoft.Json;
using System;
using System.IO;
using System.Threading.Tasks;
using System.Web;

Step 3: Writing the Code

In the Program.cs file, we can write the following code:

class Program
{
    static void Main(string[] args) => new Program().MainAsync().GetAwaiter().GetResult();

    private DiscordSocketClient _client;
    private CommandService _commands;

    public async Task MainAsync()
    {
        // Create a new Discord Client
        _client = new DiscordSocketClient();

        // Create a new Command Service
        _commands = new CommandService();

        // Register the Command Service to the Discord Client
        await _commands.AddModulesAsync(Assembly.GetEntryAssembly(), null);

        // Add Event Handlers to the Discord Client
        _client.MessageReceived += HandleCommandAsync;

        // Login to the Discord Bot
        await _client.LoginAsync(TokenType.Bot, "YOUR BOT TOKEN");

        // Start the Discord Bot
        await _client.StartAsync();

        // Wait for the bot to stay running
        await Task.Delay(-1);
    }

    private async Task HandleCommandAsync(SocketMessage messageParam)
    {
        // Ignore system messages
        var message = messageParam as SocketUserMessage;
        if (message == null) return;

        // Check if message starts with 'time'
        if (!message.Content.ToLower().StartsWith("time")) return;

        // Get command arguments
        var arg = message.Content.Substring(4);

        // Get the TimeZoneInfo of the specified timezone
        var timeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById(arg);

        // Get the current time in the specified timezone
        var time = TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, timeZoneInfo);

        // Send the current time in the specified timezone to the Discord channel
        await message.Channel.SendMessageAsync($"The current time in {arg} is {time.ToString("hh:mm tt")}.");
    }
}

Step 4: Running the Bot

Build and run your project to start the bot.

Conclusion

In this tutorial, we have created a Discord Bot in C# that displays the current time in a specific timezone. You can further customize this bot to suit your needs by adding more commands or integrating it with other APIs.
