please refer question posted http://forums.asp.net/t/1699089.aspx/1?using+system+net+classes+to+dynamically+invoke+web+service+method

stating code blocks here too..

here's code of web service..

 

using system.web; using system.web.services; using system.data;  [webservice(namespace = "http://tempuri.org/")] [webservicebinding(conformsto = wsiprofiles.basicprofile1_1)] [system.web.script.services.scriptservice] public class service : system.web.services.webservice { [webmethod]  public dataset getdata(string strcode, string strkey) {   dataset dstdata = null;   tbldata objdata = null;    objdata = new tbldata();   dstdata = objdata.getrecords(strcode);    return dstdata;  } } 

 

here's code of aspx.cs..

 

private dataset createwebrequest()  {   byte[] postbytes;   httpwebrequest request;    stringbuilder poststring = new stringbuilder();   poststring.append(    string.format(     "strcode={0}&strkey={1}",     "value1",     "value2")    );    postbytes = encoding.utf8.getbytes(poststring.tostring());    string url = "http://localhost/mywebservices/service.asmx";   //string action = url + "/getdata"; // action line 1   string action = "http://tempuri.org/getdata"; // action line 2    request = (httpwebrequest)webrequest.create(url);   request.method = "post"; // or "get" if want make request   request.contentlength = postbytes.length;   //request.contenttype = "application/x-www-form-urlencoded";    //request.contenttype = "application/xml; charset=utf-8";    request.contenttype = "text/plain";    request.headers.add("soapaction", action);    stream requeststream = request.getrequeststream();   streamwriter writer = new streamwriter(requeststream);   writer.write(poststring.tostring());   writer.close();    httpwebresponse response = (httpwebresponse)request.getresponse();   streamreader reader = new streamreader(response.getresponsestream(), encoding.utf8);   string xml = reader.readtoend();    dataset dstdata = new dataset();   dstdata.readxml(reader);    return dstdata;  } 

please let me know solution.

 

thanks..

i'm trying following code, still getting run-time error @ line calling getresponse().

  private dataset callwebservice()   {     httpwebrequest request;      string url = "http://localhost/mywebservices/service.asmx";     //string action = "/getalldata";     string action = "?op=getalldata";      //request = (httpwebrequest)webrequest.create(url);     request = (httpwebrequest)webrequest.create(url + action);     request.method = "post";     //request.contenttype = "text/xml; charset=utf-8";     //request.headers.add("soapaction", action);      httpwebresponse response = (httpwebresponse)request.getresponse(); //hangs while here , getting error "the operation has timed out"     streamreader reader = new streamreader(response.getresponsestream(), encoding.utf8);     string xml = reader.readtoend();      dataset dstdata = new dataset();     dstdata.readxml(reader);      return dstdata;   }
