Begins an asynchronous request for a Stream object to use to write data.
Assembly: System (in System.dll)
[<HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)>] abstract BeginGetRequestStream : callback:AsyncCallback * state:Object -> IAsyncResult [<HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)>] override BeginGetRequestStream : callback:AsyncCallback * state:Object -> IAsyncResult
- Type: System.Object
An object that contains state information for this request.
The method starts an asynchronous request for a stream used to send data to a file system resource. The callback method that implements the AsyncCallback delegate uses the EndGetRequestStream method to return the request stream.
The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: ExternalThreading. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
