I have killed several deer in standing corn including a couple from less than 10 feet away. (Not ten yards, ten Feet).
I wrote a lot of detail about how to do it in my book Corn-Fed Giants which was published in 1993. It's been out of print for quite a few years but you might be able to find it on Amazon.com or somewhere like that.
Basically start with the wind in your face and just poke your head in a row and look both ways. If you don't see anything, step into that row and poke your head into the next. When you see a deer, just back off a few rows, then move down the row until you are in line with the deer. The you slowly work your way across the rows once again until you can see the deer and get a shot off. It will be CLOSE!
You usually do not need binculars because you generally can only see about 30-40 yards down the rows at the most. Shots will be very close, usually less than five yards.
Best areas are grassy places in the corn. Best fields are those that are remants when most of it has been combined.
Good luck, it's a longshot in a huge field but when you find a deer it's quite a rush because it is up close action. You can get away with a lot of movment and noise because of all the movment of the corn. I've had deer see me in plain sight and just look at me because they never see people out there and it's like they can't believe their eyes.
I could tell a lot of stories about this kind of hutning... I've been doing it for 25 years. What a blast.
