The exception that is the cause of the current exception. If the innerException parameter is not null, the current exception is raised in a catch block that handles the inner exception.

An exception that is thrown as a direct result of a previous exception should include a reference to the previous exception in the InnerException property. The InnerException property returns the same value that is passed into the constructor, or null if the InnerException property does not supply the inner exception value to the constructor.

The following table shows the initial property values for an instance of IOException.
