Question

I am using ASP.NET to read a Request.InputStream and send a HttpRequest to a page that was sent to me throw a QueryString parameter, I read correctly the Request.InputStream and I make the HttpRequest correctly, but when in my Request.InputStream I find special characters like this “Porsvägen” the I get this error:
ystem.Net.WebException: The request was aborted: The request was canceled. —> System.IO.IOException: Cannot close stream until all bytes are written.
at System.Net.ConnectStream.CloseInternal(Boolean internalCall, Boolean aborting)

My code for getting the Request.InputStream is this:

string requestData = (new StreamReader(Request.InputStream)).ReadToEnd();

My code for making a HttpRequest and sending it is this:

    webRequest = (HttpWebRequest)WebRequest.Create(new Uri(urlDestination));
    webRequest.Method = "POST";

    webRequest.ContentType = "application/x-www-form-urlencoded";
    webRequest.ContentLength = requestData.Length;

    writer = new StreamWriter(webRequest.GetRequestStream());
    writer.Write(requestData, 0, requestData.Length);//<-------Here I get the ERROR
    if (writer != null)
    {
        writer.Close();
    }

Can you please tell me what is wrong with my code, because it works, but for special characters it crashes.

I have manage to overcome the error by implementing this:

        string requestData = (new StreamReader(Request.InputStream)).ReadToEnd();
        byte[] bytes = Request.ContentEncoding.GetBytes(requestData);

        Stream writer = webRequest.GetRequestStream();
        writer.Write(bytes, 0, bytes.Length);

I used Stream to write the HttpWebRequest instead of StreamWriter and read the InputStream in bytes using the ContentEncoding
