ExternalException(String)

Source:

ExternalException.cs

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

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

public ExternalException (string? message);

new System.Runtime.InteropServices.ExternalException : string -> System.Runtime.InteropServices.ExternalException

Public Sub New (message As String)

Parameters

message

String

The error message that specifies the reason for the exception.

Remarks

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

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

ExternalException(SerializationInfo, StreamingContext)

Source:

ExternalException.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 ExternalException class from serialization data.

protected:
 ExternalException(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 ExternalException (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 System.Runtime.InteropServices.ExternalException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> System.Runtime.InteropServices.ExternalException

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

Exceptions

ArgumentNullException

info is null.

Remarks

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

ExternalException(String, Exception)

Source:

ExternalException.cs

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

public:
 ExternalException(System::String ^ message, Exception ^ inner);

public ExternalException (string? message, Exception? inner);

new System.Runtime.InteropServices.ExternalException : string * Exception -> System.Runtime.InteropServices.ExternalException

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

Parameters

message

String

The error message that explains the reason for the exception.

inner

Exception

The exception that is the cause of the current exception. If the inner parameter is not null, 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 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 ExternalException.

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

Public Sub New (message As String, errorCode As Integer)

Parameters

message

errorCode

Int32

The HRESULT of the error.

Remarks

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

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