I have a console app that is making a web request to my localhost and I keep getting this error:
"System.IO.IOException: Unable to read data from the transport connection. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host\r\n at System.Net.Sockets.Socket.BeginReceive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags, AsyncCallback callback, Object state)\r\n at System.Net.Sockets.NetworkStream.BeginRead(Byte[] buffer, Int32 offset, Int32 size, AsyncCallback callback, Object state)\r\n --- End of inner exception stack trace ---\r\n at System.Net.Sockets.NetworkStream.BeginRead(Byte[] buffer, Int32 offset, Int32 size, AsyncCallback callback, Object state)\r\n at System.Net.Connection.BeginRead(Byte[] buffer, Int32 offset, Int32 size, AsyncCallback callback, Object state)\r\n at System.Net.ConnectStream.InternalBeginRead(Int32 bytesToRead, NestedSingleAsyncResult castedAsyncResult, Boolean fromCallback)\r\n at System.Net.ConnectStream.BeginReadWithoutValidation(Byte[] buffer, Int32 offset, Int32 size, AsyncCallback callback, Object state)\r\n at System.Net.ConnectStream.BeginRead(Byte[] buffer, Int32 offset, Int32 size, AsyncCallback callback, Object state)\r\n at System.Net.ConnectStream.Read(Byte[] buffer, Int32 offset, Int32 size)\r\n at System.IO.StreamReader.ReadBuffer(Char[] userBuffer, Int32 userOffset, Int32 desiredChars, Boolean& readToUserBuffer)\r\n at System.IO.StreamReader.Read(Char[] buffer, Int32 index, Int32 count)\r\n at System.IO.StreamReader.ReadToEnd()\r\n at Run.Class1.Main(String[] args) in c:\\documents and settings\\####\\my documents\\c#\\class1.cs:line 41"
The web app is in Asp.Net 2.0 and is a file system web application (not sure if this has anything to do with it).
Here is the code in the console app:
byte[] buffer;
buffer = Encoding.UTF8.GetBytes("KEY=Test");
HttpWebRequest wReq = (HttpWebRequest)WebRequest.Create("http://localhost:1991/TestApp/Test.aspx");
wReq.Method = "POST";
wReq.ContentType = "text/html";
wReq.ContentLength = buffer.Length;
using (Stream reqst = wReq.GetRequestStream()) // add form data to request stream
{
reqst.Write(buffer, 0, buffer.Length);
}
using (HttpWebResponse wRes = (HttpWebResponse)wReq.GetResponse()) // send request, get response
{
string result;
using (Stream resst = wRes.GetResponseStream()) // get HTTP response
{
StreamReader sr = new StreamReader(resst);
result = sr.ReadToEnd();
}
Console.WriteLine(result);
}
In my webpage, i have no controls, session is disabled.
The following is the code in my webpage:
<%
@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="SignIn" EnableSessionState="False" %><!

Your console.app code is correct. As for your web page - I wasn't able to make your example work; one thing I noticed you are calling your file test.aspx.cs (CodeFile="Test.aspx.cs"). I created another aspx page using this code and it worked with the code for your console app.
<Script language="C#" runat=server>
void Page_Load(object sender, EventArgs e)
{
Response.Write("KEY=DATA");
}
</Script>

hi,
i see you write in both sides in your client
reqst.Write(buffer, 0, buffer.Length);
and in your page
Response.Write("KEY=DATA");
and also you send data before your response so your connection wasn't open yet
using (Stream reqst = wReq.GetRequestStream()) // add form data to request stream
{
reqst.Write(buffer, 0, buffer.Length);
}
using (HttpWebResponse wRes = (HttpWebResponse)wReq.GetResponse()) // send request, get response
hope this helps

I'm only writing reqst.Write(buffer, 0, buffer.Length); in the client app, the Response.Write("KEY=DATA"); is written in the webpage and is what should be returned in the ResponseStream.
Basically I'm posting a webrequest in the client with the data "Key=Test" and then in the response from the webpage I should get back "KEY=DATA". Could you help me with this solution with a code example
