Hi Below is the solution where i used thread to resolve the problem try and see if it helps: public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender EventArgs e) { SendPostRequest.OnPostRequestComplete += new EventHandler (HttpRequest_OnPostRequestComplete); for (int i = 1; i { Thread reqThread = new Thread(new ParameterizedThreadStart(SendPostRequest.FireRequest)); reqThread.Start(i); } } static string[] responseResult = new string[6]; private static void HttpRequest_OnPostRequestComplete(object sender WebRequestCompletEventArgs e) { responseResult[e.Index-1] = e.ResponseText; } } public static class SendPostRequest { public static void FireRequest(object i) { HttpRequest(Convert.ToInt32(i)); } public static event EventHandler OnPostRequestComplete; private static void HttpRequest(int i) { string result = HttpPost(); if (OnPostRequestComplete != null) { WebRequestCompletEventArgs eventArgs = new WebRequestCompletEventArgs(result i); OnPostRequestComplete(i eventArgs); } } private static string HttpPost() { string field1 = abcd; string Parameters = field1= + field1; string ResP = ; System.Net.WebRequest req = System.Net.WebRequest.Create(http://localhost:25128/WebForm1.aspx); req.ContentType = application/x-www-form-urlencoded; req.Method = POST; byte[] bytes = System.Text.Encoding.ASCII.GetBytes(Parameters); req.ContentLength = bytes.Length; System.IO.Stream os = req.GetRequestStream(); os.Write(bytes 0 bytes.Length); os.Close(); System.Net.WebResponse resp = req.GetResponse(); System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream()); ResP = sr.ReadToEnd().Trim(); resp.Close(); return ResP; } } public class WebRequestCompletEventArgs : EventArgs { private string requestResponseText; private int requestIndex; public WebRequestCompletEventArgs(string reqResponseText int reqIndex) { requestResponseText = reqResponseText; requestIndex = reqIndex; } public string ResponseText {get{return requestResponseText;} } public int Index {get{return requestIndex;} } }

Hi Before return the response in HttpPost function try adding this to your code and see if it helps: resp.Close();

Please share your URI and parameters because it is working fine with below code ----------------------------------------------------------------------------------------- string field1 = abcd; string Parameters = field1= + field1; string ResP = ; System.Net.WebRequest req = System.Net.WebRequest.Create(http://localhost:25128/WebForm1.aspx); req.ContentType = application/x-www-form-urlencoded; req.Method = POST; byte[] bytes = System.Text.Encoding.ASCII.GetBytes(Parameters); req.ContentLength = bytes.Length; System.IO.Stream os = req.GetRequestStream(); os.Write(bytes 0 bytes.Length); os.Close(); System.Net.WebResponse resp = req.GetResponse(); System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream()); ResP = sr.ReadToEnd().Trim(); -------------------------------------------------------------------------------------------------- /* code for web page WebForm1.aspx*/ protected void Page_Load(object sender EventArgs e) { HttpContext.Current.Response.Write(Ashutosh); }

Hi you can write this private static void HttpRequest_OnPostRequestComplete(object sender WebRequestCompletEventArgs e) { Text1.Text = Text1.Text + e.ResponseText; } but this code cannot give the guarantee of web request response order hence you have to observe in a loop that all responses are captured and all values are set in responseResult object then you can easily iterate in this array and set your text in textbox

thnx bro But if respons be long  project send not responding for few second also if i set proxy  take long not responding for e.g private void button7_Click(object sender EventArgs e) { for (int I = 1; I { text1.Text = text1.Text + HttpPost( URI  Parameters  Proxy[I]); } } ////////////////////////////////////////////////////////////////////////////////////// public static string HttpPost(string URI string Parameters string PROXY) string ResP = ; WebProxy Prxy = new WebProxy( PROXY  true) ; System.Net.WebRequest req = System.Net.WebRequest.Create(URI); req.Proxy = PROXY ; req.ContentType = application/x-www-form-urlencoded; req.Method = POST; byte[] bytes = System.Text.Encoding.ASCII.GetBytes(Parameters); req.ContentLength = bytes.Length; System.IO.Stream os = req.GetRequestStream(); os.Write(bytes 0 bytes.Length); os.Close(); System.Net.WebResponse resp = req.GetResponse(); System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream()); ResP = sr.ReadToEnd().Trim(); return ResP; }
