How do I get coordinates of adobe fields using aspose.pdf for .net?

Hi,

I want to extract all adobe form fields and obtain their coordinates. Please find attached document that I am using for reference.

1. How can I get all adobe form fields?
2. How to I get x,y,height,width of each field?
3. How do I delete them from the document and save the document?

Can you please help me with some code in c#? I have some code in place which does not seem to work for all pdf documents that have adobe fields.

Thank you,
Sireesha
