Initializes a new instance of the IOException class with its message string set to the empty string (""), its HRESULT set to COR_E_IO, and its inner exception set to a null reference.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

The constructor initializes the Message property of the new instance to a system-supplied message that describes the error, such as "An I/O error occurred while performing the requested operation." This message takes into account the current system culture.
