XY Coordinate to Geography

[DaviKucharski]

When a user clicks on the map, I get the x,y coordinates. I would like to use there to get the Geography those x,y coordinates reside in. How would I go about that.

Thanks in advance.

Here's a sample that shows how to do this using the IdentifyTask:

You could also use the QueryTask if you only want to query one layer.
