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

public ArgumentException (
	string message,
	Exception innerException
public ArgumentException (
	String message, 
	Exception innerException
public function ArgumentException (
	message : String, 
	innerException : Exception
Not applicable.



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, the current exception is raised in a catch block that handles the inner exception.

This constructor initializes the Message property of the new instance using the value of the message parameter. The content of the message parameter is intended to be understood by humans. The caller of this constructor is required to ensure that this string has been localized for the current system culture.

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 ArgumentException.
