ArgumentException Constructor (String, String, Exception)

.NET Framework 1.1

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.

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


The error message that explains the reason for the exception.
The name of the parameter that caused the current 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.

This constructor initializes the ParamName property of the new instance using paramName. The content of paramName is intended to be understood by humans.

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.

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