How to send xml to asp page using webrequest from asp.net ?

Question

I want to post an xml document to an asp page from an asp.net page. If I use WebRequest with content/type text/xml the document never gets to the asp page. How can I do this ?

Answer 1

It's absolutely possible. Make sure that you are writing the XML to the RequestStream.

Answer 2

I do use GetRequestStream. But if you try to send xml like <data id='10'>value</data> with content-type text/xml the document never gets to its destination

Answer 3

Maybe instead of sending the whole document, you could write a temporary file and then pass the location of that temp file to the ASP page.

Answer 4

Here is a sample without any error handling (do it yourself :) ):

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(targetUri);
string sendString = formParameterName + "=" + HttpUtility.UrlEncode(xmlData);
byte[] byteStream;
byteStream = System.Text.Encoding.UTF8.GetBytes(sendString);

request.Method = POST;
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteStream.LongLength;

using(Stream writer = request.GetRequestStream())
{
    writer.Write(byteStream, 0, (int)request.ContentLength);
    writer.Flush();
}

HttpWebResponse resp = (HttpWebResponse)request.GetResponse();

//read the response
