Installation

You can find a NuGet package here https://www.nuget.org/packages/PoniLCU/

The Basics

Make an instance of LeagueClient

//At top of your code 
//using PoniLCU;
//using static PoniLCU.LeagueClient; 
  
  
//Put this in the top of your code and make it public to access it from anywhere
LeagueClient leagueClient = new LeagueClient(credentials.cmd);

//You can do either credentials.cmd or credentials.lockfile
//It doesn't really matter

Like this:

using System;
using PoniLCU;
using static PoniLCU.LeagueClient;
namespace MyApp
{
   internal class Program
   {
     //--------------
       static LeagueClient leagueClient = new LeagueClient(credentials.cmd);
     //--------------
     
       static void Main(string[] args)
       {
           Console.WriteLine("hey users");
       }
    }
}

Requests Examples

GET request

I recommend you use Async/await

var data = await leagueClient.Request(requestMethod.get, "/lol-summoner/v1/current-summoner");
Console.WriteLine(data);

If you're not going to use async, add .Result to the end of the line

var data = leagueClient.Request(requestMethod.get, "/lol-summoner/v1/current-summoner").Result;
Console.WriteLine(data);

An example on how to get specific information from the json:

var data = await leagueClient.Request(requestMethod.get, "/lol-summoner/v1/current-summoner");

var DataButJsonDeserialized = Newtonsoft.Json.Linq.JObject.Parse(data);

Console.WriteLine(DataButJsonDeserialized["displayName"]);

//The console will output your name only

PUT request

For the body, you have two options:

• Define the body string manually
• Let C# do that for us (with help of Newtonsoft.Json)

Both of these solutions will work, it is preference on how you would like to define it.

---

Using a manual body string:

string body = "{\"profileIconId\": " + 23 + "}";
await leagueClient.Request(requestMethod.put, "/lol-summoner/v1/current-summoner/icon", body);        

---

Using Newtonsoft Json:

var body = Newtonsoft.Json.JsonConvert.SerializeObject( new
	{
		profileIconId = 23
	});
await leagueClient.Request(requestMethod.put, "/lol-summoner/v1/current-summoner/icon", body);

Websocket Events Example

With PoniLCU you can subscribe to or unsubscribe from LCU events using the following code:

// Subscribe to event
leagueClient.Subscribe("/lol-gameflow/v1/gameflow-phase", GameFlowPhase);

// Unsubscribe from event
leagueClient.Unsubscribe("/lol-gameflow/v1/gameflow-phase", GameFlowPhase);

private void GameFlowPhase(OnWebsocketEventArgs obj)
{
	Console.WriteLine(obj.Data);
}
