Automated WhatsApp Message and Document Sender using .NET

Most messaging systems rely on traditional methods, but for our WhatsApp AutoSender, we needed to create a solution that would streamline communication and file sharing for years to come. Built with .NET and powered by a simple log file, our tool ensures seamless messaging and document delivery across users, regardless of location, for decades ahead.

I knew that to get it right I was going to have to replicate the conditions of a seamless communication system, so I grabbed my .NET tools, created a new project, and got to work.

WhatsApp AutoSender

This project leverages .NET to create an automated system for sending WhatsApp messages and documents. By using a simple log.txt file that stores user contact numbers and file locations, the system ensures a smooth and efficient process for automated messaging and document sharing.

Sample Log File Format

Here is the format for the log.txt file used by the WhatsApp AutoSender:

1----1111111111----D:\New Folder----Sample.pdf----15144130----Please Download It----26-11-24 1:11:11 PM

WhatsApp AutoSender Log File Format

Each log entry in the log.txt file contains the following information:

  • Status (0 or 1):

    • 0 means the PDF has not been sent yet.
    • 1 means the PDF has been sent successfully.

  • Phone Number: 1111111111
    The contact number to which the message or document is being sent.

  • File Path: D:\New Folder\Sample.pdf
    The path to the document that needs to be sent.

  • File Size: 15144130
    The size of the document in bytes.

  • Message: Please Download It
    The message accompanying the document.

  • Timestamp: 26-11-24 1:11:11 PM
    The time at which the log entry was created.

Each of these fields is separated by ---- in the log file, allowing the system to process the information and automate sending the message and document to the specified contact number.
