ApplicationException Constructors

Definition

Namespace:

System

Assembly:

System.Runtime.dll

Initializes a new instance of the ApplicationException class.

Overloads

ApplicationException()	Initializes a new instance of the ApplicationException class.
ApplicationException(String)	Initializes a new instance of the ApplicationException class with a specified error message.
ApplicationException(SerializationInfo, StreamingContext)	Obsolete. Initializes a new instance of the ApplicationException class with serialized data.
ApplicationException(String, Exception)	Initializes a new instance of the ApplicationException class with a specified error message and a reference to the inner exception that is the cause of this exception.

ApplicationException()

Source:

ApplicationException.cs

Initializes a new instance of the ApplicationException class.

public:
 ApplicationException();

public ApplicationException ();

Public Sub New ()

Remarks

This constructor initializes the Message property of the new instance to a system-supplied message that describes the error, such as "An application error has occurred." This message takes into account the current system culture.

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

Property	Value
InnerException	A null reference (Nothing in Visual Basic).
Message	The localized error message string.

ApplicationException(String)

Source:

ApplicationException.cs

Initializes a new instance of the ApplicationException class with a specified error message.

public:
 ApplicationException(System::String ^ message);

public ApplicationException (string? message);

new ApplicationException : string -> ApplicationException

Public Sub New (message As String)

Parameters

message

String

A message that describes the error.

Remarks

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 message takes into account the current system culture.

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

Property	Value
InnerException	A null reference (Nothing in Visual Basic).
Message	The error message string.

ApplicationException(SerializationInfo, StreamingContext)

Source:

ApplicationException.cs

Caution

This API supports obsolete formatter-based serialization. It should not be called or extended by application code.

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

protected:
 ApplicationException(System::Runtime::Serialization::SerializationInfo ^ info, System::Runtime::Serialization::StreamingContext context);

[System.Obsolete("This API supports obsolete formatter-based serialization. It should not be called or extended by application code.", DiagnosticId="SYSLIB0051", UrlFormat="https://aka.ms/dotnet-warnings/{0}")]
protected ApplicationException (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context);

[<System.Obsolete("This API supports obsolete formatter-based serialization. It should not be called or extended by application code.", DiagnosticId="SYSLIB0051", UrlFormat="https://aka.ms/dotnet-warnings/{0}")>]
new ApplicationException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> ApplicationException

Protected Sub New (info As SerializationInfo, context As StreamingContext)

Parameters

info

SerializationInfo

The object that holds the serialized object data.

context

StreamingContext

The contextual information about the source or destination.

Attributes

ObsoleteAttribute

Remarks

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

ApplicationException(String, Exception)

Source:

ApplicationException.cs

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

public:
 ApplicationException(System::String ^ message, Exception ^ innerException);

public ApplicationException (string? message, Exception? innerException);

new ApplicationException : string * Exception -> ApplicationException

Public Sub New (message As String, innerException As Exception)

Parameters

message

String

The error message that explains the reason for the exception.

innerException

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.

Remarks

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 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 ApplicationException.

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