Voorbeelden

In het volgende codevoorbeeld wordt de waarde van deze eigenschap ingesteld.

using System.Net;
using System.Text;
using System.IO;

    public class Test
    {
        // Specify the URL to receive the request.
        public static void Main (string[] args)
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(args[0]);

            // Set some reasonable limits on resources used by this request
            request.MaximumAutomaticRedirections = 4;
            request.MaximumResponseHeadersLength = 4;
            // Set credentials to use for this request.
            request.Credentials = CredentialCache.DefaultCredentials;
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            Console.WriteLine("Content length is {0}", response.ContentLength);
            Console.WriteLine("Content type is {0}", response.ContentType);

            // Get the stream associated with the response.
            Stream receiveStream = response.GetResponseStream();

            // Pipes the stream to a higher level stream reader with the required encoding format.
            StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);

            Console.WriteLine("Response stream received.");
            Console.WriteLine(readStream.ReadToEnd());
            response.Close();
            readStream.Close();
        }
    }

/*
The output from this example will vary depending on the value passed into Main
but will be similar to the following:

Content length is 1542
Content type is text/html; charset=utf-8
Response stream received.
<html>
...
</html>

Opmerkingen

Caution

WebRequest, HttpWebRequest, ServicePointen WebClient zijn verouderd en u moet ze niet gebruiken voor nieuwe ontwikkeling. Gebruik in plaats daarvan HttpClient.

De MaximumAutomaticRedirections eigenschap stelt het maximum aantal omleidingen in dat de aanvraag moet volgen als de AllowAutoRedirect eigenschap is true.
