I want to highlight some text from PDF by doing string comparison ,mark it with some kind of marker, highlight entire row of table if specific string is present in that row. Is it is possible to do this using Acrobat SDK / PDF Library SDK in ASP.NET or C#.NET(windows application)?

Not the Acrobat SDK, it isn't for servers. PDF Library? Well, functionally yes but you'd write in C++. You would need to start with a good basic familiarity with PDF internals (PDF Reference, ISO 32000-1). Can extract the words on a page, and hence search for strings by looking at the words. Highligh annotations can be added but in untagged PDFs THERE ARE NO TABLES. You may be looking for something that doesn't exist. If you want to highlight an area bounded by table cells (as designed, before PDF creation) you may need either predefined table locations or fuzzy logic to find them.
