IOException Constructor (String, Exception)

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.

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

Syntax

'Declaration
Public Sub New ( _
    message As String, _
    innerException As Exception _
)
public IOException(
    string message,
    Exception innerException
)

Parameters

  • message
    Type: System.String
    The error message that explains the reason for the exception.
  • innerException
    Type: System.Exception
    The exception that is the cause of the current exception. If the innerException parameter is not nulla null reference (Nothing in Visual Basic), the current exception is raised in a catch block that handles the inner exception.

Remarks

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 nulla 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.
