Creating a request collection to send and get one response C#

Question

I am working on redacting a pdf file using Aspose.pdf but I want to be able to redact multiple area on the same page.

I have been sending my request using this:

public record redactPdfRequest(string encodedString, int pages, int coordinateX, int coordinateY, int width, int height);

and I have been getting something like this in return:

{
  "encodedString": "string",
  "pages": 0,
  "coordinateX": 0,
  "coordinateY": 0,
  "width": 0,
  "height": 0
}

But what I am looking for is a way to actually create multiple instance of the request above and read from them to perform multiple redaction. For example

{ "encodedString": "string", "pages": 0, "coordinateX": 0, "coordinateY": 0, "width": 0, "height": 0 }

{ "encodedString": "string", "pages": 0, "coordinateX": 0, "coordinateY": 0, "width": 0, "height": 0 }

And here I can have multiple of that request above.

Thank you and any help is appreciated.
