ArgumentNullException(SerializationInfo, StreamingContext)

Initializes a new instance of the ArgumentNullException class with serialized data.

ArgumentNullException(String, Exception)

ArgumentNullException()

Initializes a new instance of the ArgumentNullException class.

public ArgumentNullException ();

The following table shows the initial property values for an instance of ArgumentNullException.

Property Value
InnerException A null reference (Nothing in Visual Basic).
Message A localized error message string, such as "Value cannot be null." for the English language.

public ArgumentNullException (string paramName);
Parameters
paramName
String

The name of the parameter that caused the exception.

Remarks

This constructor initializes the Message property of the new instance to a system-supplied message that describes the error and includes the parameter name. This message takes into account the current system culture.

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

The following table shows the initial property values for an instance of ArgumentNullException.

ArgumentNullException(SerializationInfo, StreamingContext)

Initializes a new instance of the ArgumentNullException class with serialized data.

[System.Security.SecurityCritical]
protected ArgumentNullException (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context);
Parameters
info
SerializationInfo

The object that holds the serialized object data.

context
StreamingContext

An object that describes the source or destination of the serialized data.

Remarks

This constructor is called during deserialization to reconstitute the exception object transmitted over a stream. For more information, see XML and SOAP Serialization.

Security

SecurityPermission
for providing serialization services. Associated enumeration: SerializationFormatter Security action: LinkDemand

SecurityCriticalAttribute
requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.

ArgumentNullException(String, Exception)

Initializes a new instance of the ArgumentNullException class with a specified error message and the exception that is the cause of this exception.

public ArgumentNullException (string message, Exception innerException);
