In the above code:

We first define the URL of the image that we want to convert to a byte array.

Then, we call the ConvertImageToByteArray method and pass the image URL as an argument.

Inside the ConvertImageToByteArray method, we use the WebClient class to download the image data as a byte array.

Finally, we return the byte array containing the image data.

You can further extend this code to suit your specific requirements, such as saving the byte array to a file or storing it in a database.

This approach provides a straightforward way to convert an image from a URL to a byte array in C, allowing you to efficiently handle image data in your applications.
