Description

Starts an asynchronous HTTP request using the DELETE HTTP request method.

When you call BeginDelete, you must provide the data required to perform your HTTP request:

  • AURL is the target URL of your request.

  • AResponseContent (optional) is a stream where you want to receive the response data as your HTTP client downloads the response data from the target server.

    If you do not specify a stream for AResponseContent, you can wait for your HTTP client to download the whole response data, and obtain the response data as a stream from the ContentStream property of the asynchronous result object that BeginDelete returns.
  • AHeaders (optional) is a list of headers to include in the request.
  • AsyncCallback (optional) is a callback procedure to be called when a response is received or the request fails.
  • AsyncCallbackEvent (optional) is an event handler to be called when a response is received or the request fails.

For more information, see BeginExecute.
