Which method allows you to obtain the response stream from a WebRequest?

1. request.GetResponseStream()

2. request.Response()

3. request.GetResponse()

4. request.StreamResponse()

The correct answer is: request.GetResponse()

To obtain the response stream from a WebRequest, you should use the method that retrieves the entire response from the server. The correct method is designed to send the request to the specified resource and capture the server's response. Using the method request.GetResponse() initiates the request and returns a WebResponse object, which contains all the information sent back by the server, including headers and a stream to read the actual data returned. Once you have the WebResponse object, you can then call the GetResponseStream() method on that object to obtain the response stream specifically. This two-step process is essential in working with WebRequests, as it allows you to handle the request and its response effectively. The other choices do not represent valid methods to obtain the response stream directly. Some might mislead about the underlying mechanism of request and response handling in the context of web communications in .NET, while others do not correspond to any method available in the framework. Understanding how to properly retrieve and handle a WebResponse is crucial for making efficient web-based applications.
