How to: Check an Exception's Inner Exception

In cases where an exception is thrown as a direct result of a previous exception, the InnerException property describes the original error. This information may allow you to handle the error more efficiently. If there is no original error, the value of InnerException will be a null reference or Nothing in Visual Basic. This property is read-only.

Note
The options available in dialog boxes, and the names and locations of menu commands you see, might differ from what is described in Help depending on your active settings or edition. This Help page was written with General Development Settings in mind. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Visual Studio Settings.
