IOException Constructor (String, Exception)

.NET Framework 1.1

Initializes a new instance of the IOException class with a specified error message and a reference to the inner exception that is the cause of this exception.

[Visual Basic]
Public Sub New( _
   ByVal message As String, _
   ByVal innerException As Exception _
public IOException(
   string message,
 Exception innerException
public: IOException(
   String* message,
 Exception* innerException
public function IOException(
   message : String,
 innerException : Exception


The error message that explains the reason for the exception.
The exception that is the cause of the current exception. If the innerException parameter is not a null reference (Nothing in Visual Basic), 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 a null reference (Nothing in Visual Basic) 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.

Property Value
InnerException The inner exception reference.
Message The error message string.

For more information on inner exceptions, see InnerException.
