Definition

Namespace:

System.Net.Sockets

Assembly:

System.Net.Sockets.dll

Overloads

SendAsync(Socket, ReadOnlyMemory<Byte>, SocketFlags, CancellationToken)	Sends data to a connected socket.
SendAsync(Socket, ArraySegment<Byte>, SocketFlags)	Sends data to a connected socket.
SendAsync(Socket, IList<ArraySegment<Byte>>, SocketFlags)	Sends data to a connected socket.

SendAsync(Socket, ReadOnlyMemory<Byte>, SocketFlags, CancellationToken)

Source:

SocketTaskExtensions.cs

Sends data to a connected socket.

public static System.Threading.Tasks.ValueTask<int> SendAsync (this System.Net.Sockets.Socket socket, ReadOnlyMemory<byte> buffer, System.Net.Sockets.SocketFlags socketFlags, System.Threading.CancellationToken cancellationToken = default);

static member SendAsync : System.Net.Sockets.Socket * ReadOnlyMemory<byte> * System.Net.Sockets.SocketFlags * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTask<int>

<Extension()>
Public Function SendAsync (socket As Socket, buffer As ReadOnlyMemory(Of Byte), socketFlags As SocketFlags, Optional cancellationToken As CancellationToken = Nothing) As ValueTask(Of Integer)

Parameters

socket

Socket

The socket to perform the operation on.

buffer

ReadOnlyMemory<Byte>

A region of memory that contains the data to send.

socketFlags

SocketFlags

A bitwise combination of the SocketFlags values.

cancellationToken

CancellationToken

A cancellation token that can be used to signal the asynchronous operation should be canceled.

Returns

ValueTask<Int32>

A task that completes with number of bytes sent to the socket if the operation was successful. Otherwise, the task will complete with an invalid socket error.

Exceptions

SocketException

An error occurred when attempting to access the socket.

ObjectDisposedException

The Socket has been closed.

OperationCanceledException

The cancellation token was canceled. This exception is stored into the returned task.

SendAsync(Socket, ArraySegment<Byte>, SocketFlags)

Source:

SocketTaskExtensions.cs

Sends data to a connected socket.

public:
[System::Runtime::CompilerServices::Extension]
 static System::Threading::Tasks::Task<int> ^ SendAsync(System::Net::Sockets::Socket ^ socket, ArraySegment<System::Byte> buffer, System::Net::Sockets::SocketFlags socketFlags);

public static System.Threading.Tasks.Task<int> SendAsync (this System.Net.Sockets.Socket socket, ArraySegment<byte> buffer, System.Net.Sockets.SocketFlags socketFlags);

static member SendAsync : System.Net.Sockets.Socket * ArraySegment<byte> * System.Net.Sockets.SocketFlags -> System.Threading.Tasks.Task<int>

<Extension()>
Public Function SendAsync (socket As Socket, buffer As ArraySegment(Of Byte), socketFlags As SocketFlags) As Task(Of Integer)

Parameters

socket

Socket

The socket to perform the operation on.

buffer

ArraySegment<Byte>

An array of type Byte that contains the data to send.

socketFlags

SocketFlags

A bitwise combination of the SocketFlags values.

Returns

Task<Int32>

An asynchronous task that completes with number of bytes sent to the socket if the operation was successful. Otherwise, the task will complete with an invalid socket error.

Exceptions

SocketException

An error occurred when attempting to access the socket.

ObjectDisposedException

The Socket has been closed.

SendAsync(Socket, IList<ArraySegment<Byte>>, SocketFlags)

Source:

SocketTaskExtensions.cs

Sends data to a connected socket.

public:
[System::Runtime::CompilerServices::Extension]
 static System::Threading::Tasks::Task<int> ^ SendAsync(System::Net::Sockets::Socket ^ socket, System::Collections::Generic::IList<ArraySegment<System::Byte>> ^ buffers, System::Net::Sockets::SocketFlags socketFlags);

public static System.Threading.Tasks.Task<int> SendAsync (this System.Net.Sockets.Socket socket, System.Collections.Generic.IList<ArraySegment<byte>> buffers, System.Net.Sockets.SocketFlags socketFlags);

static member SendAsync : System.Net.Sockets.Socket * System.Collections.Generic.IList<ArraySegment<byte>> * System.Net.Sockets.SocketFlags -> System.Threading.Tasks.Task<int>

<Extension()>
Public Function SendAsync (socket As Socket, buffers As IList(Of ArraySegment(Of Byte)), socketFlags As SocketFlags) As Task(Of Integer)

Parameters

socket

Socket

The socket to perform the operation on.

buffers

IList<ArraySegment<Byte>>

An array that contains the data to send.

socketFlags

SocketFlags

A bitwise combination of the SocketFlags values.

Returns

Task<Int32>

An asynchronous task that completes with number of bytes sent to the socket if the operation was successful. Otherwise, the task will complete with an invalid socket error.

Exceptions

ArgumentNullException

buffers is null.

SocketException

An error occurred when attempting to access the socket.

ObjectDisposedException

The Socket has been closed.
