This article shows you how to send a document (e.g. a PDF file) to a registered Telegram user in Microsoft’s .NET language: C# using Visual Studio 2019.
If you are using Visual Studio 2022, please read this tutorial instead.
Before the recipient can receive your Telegram message, she MUST register with the WhatsMate Telegram Gateway. Instructions are available on the official site. Unregistered users will never receive messages from the Gateway.
To send a Telegram message containing a PDF document in C# using Visual Studio 2019, do this:
- First, learn how to send a simple text message on the official site.
- With the above knowledge, you can now download our sample code.
- Locate the file
cs/send-telegram-pdf.cs. - Study the
C#source code and customize the TODO/FIXME lines.- Among other things, put down YOUR OWN number as the recipient. You can’t send messages to strangers because we are against SPAMMERS.
- Run the
C#program in Visual Studio to send yourself the first PDF file!
Happy coding :)
