Q:

Using HttpWebRequest to POST to a form on an outside server

I am trying to simulate a POST to a form on an external server that does not require any authentication, and capture a sting containing the resulting page.  This is the first time I have done this so I am looking for some help with what I have so far.  This is what the form looks like:
<FORM METHOD="POST" ACTION="/controller" NAME="GIN">
<INPUT type="hidden" name="JSPName" value="GIN">

Field1:
<INPUT type="text" name="Field1" size="30"
                maxlength="60" class="txtNormal" value=""> 

</FORM>

This is what my code looks like:
    ASCIIEncoding encoding = new ASCIIEncoding();
    string postData = "Field1=VALUE1&JSPName=GIN";
    byte[] data = encoding.GetBytes(postData);
    // Prepare web request...
    HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("https://XXX/controller");
    myRequest.Method = "POST";
    myRequest.ContentType = "text/html";
    myRequest.ContentLength = data.Length;
    Stream newStream = myRequest.GetRequestStream();
    // Send the data.
    newStream.Write(data, 0, data.Length);

    StreamReader reader = new StreamReader(newStream);
    string text = reader.ReadToEnd(); 

    MessageBox.Show(text);

    newStream.Close();

Currently, the code returns "Stream was not readable".

A:

You want to read the Response stream:
using (var resp = myRequest.GetResponse())
{
    using (var responseStream = resp.GetResponseStream())
    {
        using (var responseReader = new StreamReader(responseStream))
        {
        }
    }
}
