TaskCanceledException()

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

Initializes a new instance of the TaskCanceledException class with a system-supplied message that describes the error.

public:
 TaskCanceledException();

public TaskCanceledException ();

Public Sub New ()

Remarks

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

The following table shows the initial property values for an instance of OperationCanceledException:

Property	Value
InnerException	`null`.
Message	The localized error message string.

Applies to

TaskCanceledException(String)

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

Initializes a new instance of the TaskCanceledException class with a specified message that describes the error.

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

public TaskCanceledException (string message);

public TaskCanceledException (string? message);

new System.Threading.Tasks.TaskCanceledException : string -> System.Threading.Tasks.TaskCanceledException

Public Sub New (message As String)

Parameters

message: String

The message that describes the exception. The caller of this constructor is required to ensure that this string has been localized for the current system culture.

Remarks

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

Property	Value
InnerException	`null`.
Message	The error message string specified in `message`.

Applies to

TaskCanceledException(Task)

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

Initializes a new instance of the TaskCanceledException class with a reference to the Task that has been canceled.

public:
 TaskCanceledException(System::Threading::Tasks::Task ^ task);

public TaskCanceledException (System.Threading.Tasks.Task task);

public TaskCanceledException (System.Threading.Tasks.Task? task);

new System.Threading.Tasks.TaskCanceledException : System.Threading.Tasks.Task -> System.Threading.Tasks.TaskCanceledException

Public Sub New (task As Task)

Parameters

task: Task

A task that has been canceled.

Applies to

TaskCanceledException(SerializationInfo, StreamingContext)

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.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 TaskCanceledException class with serialized data.

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

protected TaskCanceledException (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 TaskCanceledException (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context);

new System.Threading.Tasks.TaskCanceledException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> System.Threading.Tasks.TaskCanceledException

[<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.Threading.Tasks.TaskCanceledException : System.Runtime.Serialization.SerializationInfo * System.Runtime.Serialization.StreamingContext -> System.Threading.Tasks.TaskCanceledException

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.

Applies to

TaskCanceledException(String, Exception)

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

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

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

public TaskCanceledException (string message, Exception innerException);

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

new System.Threading.Tasks.TaskCanceledException : string * Exception -> System.Threading.Tasks.TaskCanceledException

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

Parameters

message: String

The message that describes the exception. The caller of this constructor is required to ensure that this string has been localized for the current system culture.

innerException: Exception

The exception that is the cause of the current exception. If the innerException 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 TaskCanceledException.

Property	Value
InnerException	`null`.
Message	The error message string specified in `message`.

Applies to

TaskCanceledException(String, Exception, CancellationToken)

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

Source:: TaskCanceledException.cs

public:
 TaskCanceledException(System::String ^ message, Exception ^ innerException, System::Threading::CancellationToken token);

public TaskCanceledException (string? message, Exception? innerException, System.Threading.CancellationToken token);

public TaskCanceledException (string message, Exception innerException, System.Threading.CancellationToken token);

new System.Threading.Tasks.TaskCanceledException : string * Exception * System.Threading.CancellationToken -> System.Threading.Tasks.TaskCanceledException

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

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.
