Definition

Namespace:

System.Data.SqlTypes

Assembly:

System.Data.SqlClient.dll

Package:

System.Data.SqlClient v4.8.6

Begins an asynchronous write operation.

public:
 override IAsyncResult ^ BeginWrite(cli::array <System::Byte> ^ buffer, int offset, int count, AsyncCallback ^ callback, System::Object ^ state);

public override IAsyncResult BeginWrite (byte[] buffer, int offset, int count, AsyncCallback callback, object state);

override this.BeginWrite : byte[] * int * int * AsyncCallback * obj -> IAsyncResult

Public Overrides Function BeginWrite (buffer As Byte(), offset As Integer, count As Integer, callback As AsyncCallback, state As Object) As IAsyncResult

Parameters

buffer

Byte[]

The buffer to write data from.

offset

Int32

The byte offset in buffer from which to begin writing.

count

Int32

The maximum number of bytes to write.

callback

AsyncCallback

An optional asynchronous callback, to be called when the write is complete.

state

Object

A user-provided object that distinguishes this particular asynchronous write request from other requests.

Returns

IAsyncResult
