OpenWriteCompletedEventArgs::Result Property


Gets a writable stream that is used to send data to a server.

Namespace:   System.Net
Assembly:  System (in System.dll)

property Stream^ Result {
	Stream^ get();

Property Value

Type: System.IO::Stream^

A Stream where you can write data to be uploaded.

You should check the Error and Cancelled properties before using the stream returned by this property. If the Error property's value is an Exception object or the Cancelled property's value is true, the asynchronous operation did not complete correctly and the Result property's value will not be valid.

The following code example uses the stream returned by this property.

void OpenWriteCallback2( Object^ /*sender*/, OpenWriteCompletedEventArgs^ e )
   Stream^ body = nullptr;
   StreamWriter^ s = nullptr;
      body = dynamic_cast<Stream^>(e->Result);
      s = gcnew StreamWriter( body );
      s->AutoFlush = true;
      s->Write( "This is content data to be sent to the server." );
      if ( s != nullptr )
      if ( body != nullptr )
