• 方法一：
  1.Close the solution.
  2.Delete the intellisense database file for the solution: [solution].ncb or [solution].suo
  3.Reopen the solution.
  4.Optional: Rebuild the solution.

• 方法二
  In Tools - Options, type "IntelliSense" into the search box, and click on C/C++ - Advanced. In the Browsing/Navigation section, change Disable Database to False, if it is not so already.

After re-enabling, close and reopen to force rebuild. NOTE: IntelliSense will produce large files on disk (*.sdf and ipch) that should be excluded from Git, for example.
