Hello Lauren,
The answer to that question is no. Its simply to hot, and radiation would also damage the spacecrafts systems at too close a distance.
The closest any spacecraft have come is going into orbit around Venus, or flybys of Mercury. There has been a polar orbiting mission of the Sun, though at a safe distance by a solar spacecraft known as Ulysses. You can see more on that here;

Also there is a spacecraft headed for orbit in a few years around Mercury, known as the Mercury Messenger mission, headed by Johns Hopkins University. The spacecraft recently flew by Mercury, take a look at the images it took by visiting the Mercury Messenger website;
