Welcome to Game Development Stack Exchange
We're a little bit different from other sites. Here's how:
Ask questions, get answers, no distractions
This site is all about getting answers. It's not a discussion forum. There's no chit-chat.
Just questions...
...and answers.
Good answers are voted up and rise to the top.
The best answers show up first so that they are always easy to find.
The person who asked can mark one answer as "accepted".
Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.
XNA Sprite mouse selection with layered/overlapping sprites
If I use mouse coordinates to select a sprite does XNA provide a built in way to return the top-most sprite on the screen at a coordinate?
I am trying to highlight the selected sprite, but when iterating through my sprites at the specific mouse location there can be multiple sprites found. The way my game works any one of the sprites found is valid to be on top.

I don't believe XNA has a built in way to do this. You should definitely implement some kind of ordering or layering system so one sprite gains precedence over the others (unless your game needs multiple sprites to be selected at once from the same mouse click). Once a sprite processes the selection no other sprites should be given the chance to.

It sounds like you need to assign a "depth" or "Z" value to your sprites that defines which is "on top" of each other. Then you would iterate through the sprites as usual but the sprite returned would have the highest "Z" value.

Get answers to practical, detailed questions
Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.
Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.
Questions that need improvement may be closed until someone fixes them.
Tags make it easy to find interesting questions
All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.
Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.
