Définition des données de corps d'une requête WebRequest

Je crée une demande Web dans ASP.NET et je dois ajouter un tas de données au corps. Comment je fais ça?

var request = HttpWebRequest.Create(targetURL);
request.Method = "PUT";
response = (HttpWebResponse)request.GetResponse();
c#httpwebrequest

Avec HttpWebRequest.GetRequestStream

Exemple de code de http://msdn.Microsoft.com/en-us/library/d4cek6cc.aspx

string postData = "firstone=" + inputData;
ASCIIEncoding encoding = new ASCIIEncoding ();
byte[] byte1 = encoding.GetBytes (postData);

// Set the content type of the data being posted.
myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";

// Set the content length of the string being posted.
myHttpWebRequest.ContentLength = byte1.Length;

Stream newStream = myHttpWebRequest.GetRequestStream ();

newStream.Write (byte1, 0, byte1.Length);

À partir d'un de mes propres codes:

var request = (HttpWebRequest)WebRequest.Create(uri);
request.Credentials = this.credentials;
request.Method = method;
request.ContentType = "application/atom+xml;type=entry";
using (Stream requestStream = request.GetRequestStream())
using (var xmlWriter = XmlWriter.Create(requestStream, new XmlWriterSettings() { Indent = true, NewLineHandling = NewLineHandling.Entitize, }))
{
    cmisAtomEntry.WriteXml(xmlWriter);
}

try 
{    
    return (HttpWebResponse)request.GetResponse();  
}
catch (WebException wex)
{
    var httpResponse = wex.Response as HttpWebResponse;
    if (httpResponse != null)
    {
        throw new ApplicationException(string.Format(
            "Remote server call {0} {1} resulted in a http error {2} {3}.",
            method,
            uri,
            httpResponse.StatusCode,
            httpResponse.StatusDescription), wex);
    }
    else
    {
        throw new ApplicationException(string.Format(
            "Remote server call {0} {1} resulted in an error.",
            method,
            uri), wex);
    }
}
catch (Exception)
{
    throw;
}

Cela devrait aider:

var request = (HttpWebRequest)WebRequest.Create("http://example.com/page.asp");

string stringData = ""; //place body here
var data = Encoding.ASCII.GetBytes(stringData); // or UTF8

request.Method = "PUT";
request.ContentType = ""; //place MIME type here
request.ContentLength = data.Length;

var newStream = request.GetRequestStream();
newStream.Write(data, 0, data.Length);
newStream.Close();
