ArgumentException Constructor (String, String, Exception)

July 28, 2014

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

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

public ArgumentException(
	string message,
	string paramName,
	Exception innerException
)

Parameters

message
Type: System.String
The error message that explains the reason for the exception.
paramName
Type: System.String
The name of the parameter that caused the current exception.
innerException
Type: System.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 null 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.
