LINE Developers.Net

This C# Library is implemented of the LINE Developers APIs. and This is an unofficial LINE Developers library. There are so many features in LINE Developers APIs. However couldn't test such of features which are not offer in KOREA and some of pay features. but It'll works well. I hope it's helpful to develop message send and chatbot via LINE Messenger.

1. Getting started

2. Library introduction

2-1. LineMessagingClient class

There are exists each class by unit of feature. for instance, it offer same features both a LineMessaingClient.Insight and a LineInsightClient class. but I recommend that you should use a LineMessagingClient class instead of each class.

  • example)
    using Line.Message;
    
    using (var client = new LineMessagingClient("your access token"))
    {
        await client.Message.SendBroadcastMessageAsync(new TextMessage("hello world"));
        await client.Message.SendReplyMessageAsync("reply token", new TextMessage("hello world"));
        await client.Insight.GetNumberOfMessageDeliveriesAsync(new DateOnly(2022, 10, 31));
        await client.RichMenu.DownloadRichMenuImageAsync("test richmenu id", @"c:\temp\test.jpg");
    }
