FormatException Constructor (String, Exception)

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

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

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

public FormatException(
	string message,
	Exception innerException


Type: System.String
The error message that explains the reason for the exception.
Type: System.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 FormatException.




The inner exception reference.


The error message string.
