SystemException Constructors

Definition

Initializes a new instance of the SystemException class.

Overloads

SystemException()

Initializes a new instance of the SystemException class.

SystemException(String)

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

SystemException(SerializationInfo, StreamingContext)
Obsolete.

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

SystemException(String, Exception)

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

SystemException()

Source:
SystemException.cs
Source:
SystemException.cs
Source:
SystemException.cs

Initializes a new instance of the SystemException class.

public:
 SystemException();
public SystemException ();
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 "A system error has occurred." This message takes into account the current system culture.

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

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

Applies to

SystemException(String)

Source:
SystemException.cs
Source:
SystemException.cs
Source:
SystemException.cs

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

public:
 SystemException(System::String ^ message);
public SystemException (string? message);
public SystemException (string message);
new SystemException : string -> SystemException
Public Sub New (message As String)

Parameters

message
String

The message that describes the error.

Remarks

The content of the message parameter should be understandable to the user. The caller of this constructor is required to ensure that this string has been localized for the current system culture.

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

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

Applies to

SystemException(SerializationInfo, StreamingContext)

Source:
SystemException.cs
Source:
SystemException.cs
Source:
SystemException.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 SystemException class with serialized data.

protected:
 SystemException(System::Runtime::Serialization::SerializationInfo ^ info, System::Runtime::Serialization::StreamingContext context);
protected SystemException (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 SystemException (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context);
new SystemException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> SystemException
[<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 SystemException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> SystemException
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

Remarks

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

Applies to

SystemException(String, Exception)

Source:
SystemException.cs
Source:
SystemException.cs
Source:
SystemException.cs

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

public:
 SystemException(System::String ^ message, Exception ^ innerException);
public SystemException (string? message, Exception? innerException);
public SystemException (string message, Exception innerException);
new SystemException : string * Exception -> SystemException
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 (Nothing in Visual Basic), the current exception is raised in a catch block that handles the inner exception.

Remarks

An exception that is thrown as a direct result of a previous exception can 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 SystemException.

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