Begins an asynchronous write operation. (Consider using WriteAsync(Byte[], Int32, Int32) instead.)

public:
 virtual IAsyncResult ^ BeginWrite(cli::array <System::Byte> ^ buffer, int offset, int count, AsyncCallback ^ callback, System::Object ^ state);
public virtual IAsyncResult BeginWrite(byte[] buffer, int offset, int count, AsyncCallback? callback, object? state);
public virtual IAsyncResult BeginWrite(byte[] buffer, int offset, int count, AsyncCallback callback, object state);
public virtual IAsyncResult BeginWrite(byte[] buffer, int offset, int count, AsyncCallback callback, object? state);
abstract member BeginWrite : byte[] * int * int * AsyncCallback * obj -> IAsyncResult
override this.BeginWrite : byte[] * int * int * AsyncCallback * obj -> IAsyncResult
Public Overridable 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
