Stream was not readable - nothing is disposed of, why does this not work?

Question

I have the following code:

 // Create POST data and convert it to a byte array.
 string postData = "name=t&description=tt";
 byte[] byteArray = Encoding.UTF8.GetBytes(postData);
 // Set the ContentType property of the WebRequest.
 request.ContentType = "application/x-www-form-urlencoded";
 // Set the ContentLength property of the WebRequest.
 request.ContentLength = byteArray.Length;
 // Get the request stream.
 using (StreamReader reader = new StreamReader(request.GetRequestStream()))
 {
     string s = reader.ReadToEnd();
 }

When the flow hits the using (..... ) statement, I get the following exception:

Stream was not readable

I want to read the entire request stream into a string, nothing is closed, so the code should work?

A similar situation was answered and may help, look at: http://stackoverflow.com/a/43981770/2791237 — João Paulo Melo, May 15 '17 at 14:19

You write to the Request stream and read from the Response stream.

    string postData = "name=t&description=tt";
    byte[] byteArray = Encoding.UTF8.GetBytes(postData);
    // Set the ContentType property of the WebRequest.
    request.ContentType = "application/x-www-form-urlencoded";
    // Set the ContentLength property of the WebRequest.
    request.ContentLength = byteArray.Length;
    // Get the request stream.

    var stream = request.GetRequestStream();
    stream.Write( byteArray, 0, byteArray.Length );

Thanks for that. However, can I not see the xml body of the request which is being sent out? – GurdeepS Mar 22 '11 at 00:05
@dotnetdev - maybe in the debugger. In any event, it's not XML, it's simply the string you specified, URL-encoded, so you already have the contents. – tvanfosson Mar 22 '11 at 00:09
@dotnetdev - if you absolutely had to you could derive your own request class from HttpWebRequest and override GetRequestStream so that it it returned the underlying stream wrapped with a filter. You could make the filter store the actual request written to the stream and make it available to you via some other property on your class. – tvanfosson Mar 22 '11 at 00:16

The stream is not readable, because it's intended to be written to. See this link for a simple example:
