And now here I explain to how to call web service without adding web reference using C# code.

Now copy the following code in your page.

this is the method in MyWebService.asmx wants to call without adding web reference
 

    [WebMethod]

    public string MyDemoWebService(string data1, string data2)

    {

       // Your code here

       return "";

    }

 Now copy the following code in code behind where you want to call web service.

private string CallWebService(string data1, string data2)

    {

    string url = "http://www.YOURLIVESITEURL/MyWebService.asmx/MyDemoWebService";

        if (Request.IsLocal)

        {

            url = "http://localhost:8945/MyWebService.asmx/MyDemoWebService";

        }

        string result = "";

        string strPost = "data1=" + data1+ "&data2=" + data2;

        StreamWriter myWriter = null;

        HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);

        objRequest.Method = "POST";

        objRequest.Timeout = 200000; // this should be greater than IIS / web server's timeout

        objRequest.ContentLength = strPost.Length;

        objRequest.ContentType = "application/x-www-form-urlencoded";

        objRequest.KeepAlive = false;

        try

        {

            myWriter = new StreamWriter(objRequest.GetRequestStream());

            myWriter.Write(strPost);

        }

        catch (Exception e)

        {

            throw new Exception(e.ToString());

        }

        finally

        {

            myWriter.Close();

        }

        HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();

        using (StreamReader sr = new StreamReader(objResponse.GetResponseStream)))

        {

            result = sr.ReadToEnd();

            sr.Close();

        }

        return result;

    }

 

  Now call above function CallWebService in your button click event with given parameter and your web service is called without adding web reference. you will get response in result string variavle.

Now run your project and check.
