GZipStream.BeginWrite(Byte[], Int32, Int32, AsyncCallback, Object) Method
Important

Begins an asynchronous write operation. (Consider using the WriteAsync(Byte[], Int32, Int32) method instead.)
public:
override IAsyncResult ^ BeginWrite(cli::array <System::Byte> ^ array, int offset, int count, AsyncCallback ^ asyncCallback, System::Object ^ asyncState);
public:

public override IAsyncResult BeginWrite (byte[] array, int offset, int count, AsyncCallback? asyncCallback, object? asyncState);
public override IAsyncResult BeginWrite (byte[] buffer, int offset, int count, AsyncCallback? asyncCallback, object? asyncState);

- arraybuffer
- Byte[]
The buffer containing data to write to the current stream.
- offset
- Int32
The byte offset at which to begin writing.
- count
- Int32
The maximum number of bytes to write.
- asyncCallback
- AsyncCallback
An optional asynchronous callback to be called when the write operation is complete.
- asyncState
- Object
A user-provided object that distinguishes this particular asynchronous write request from other requests.
An object that represents the asynchronous write operation, which could still be pending.
Starting with .NET Framework 4.5, you can perform asynchronous write operations by using the Stream.WriteAsync method. The BeginWrite method is still available in current versions to support legacy code; however, you can implement asynchronous I/O operations more easily by using the new async methods. For more information, see Asynchronous File I/O.
The BeginWrite method starts an asynchronous write operation to a GZipStream stream object.
You must create a callback method that implements the AsyncCallback delegate and pass its name to the BeginWrite method.
