I got a walkaround to address this issue by trying. Here is the solution: instead of using loadparams(), just assign the querystring in the post request to OWSRequest. <br>It worked. :-)<br><br><font style="" face="Courier New"> public void ProcessRequest (HttpContext context) {</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> try</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> {</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> OWSRequest req = new OWSRequest();</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> System.Collections.Specialized.NameValueCollection queryStr = context.Request.QueryString;</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> for (int i = 0; i < queryStr.Count; ++i) req.setParameter(queryStr.GetKey(i), queryStr.Get(i));</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> <br> if (context.Request.HttpMethod == "POST")</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> {</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> StreamReader reader = new StreamReader(context.Request.InputStream, context.Request.ContentEncoding); //System.Text.Encoding.UTF8</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> String sXMLRequest = reader.ReadToEnd();</font><font style="" face="Courier New"><br></font><b><font style="" face="Courier New"> req.type = MS_REQUEST_TYPE.MS_POST_REQUEST;</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> req.postrequest = sXMLRequest;</font></b><font style="" face="Courier New"><br></font><font style="" face="Courier New"> }</font><font style="" face="Courier New"><br></font><font style="" face="Courier New"> ...</font><br><br><br><br><br><br><hr id="stopSpelling">Date: Fri, 10 Sep 2010 09:36:04 +0200<br>Subject: Re: [mapserver-users] C# mapscripts and WFS Service , xml-encoded Post Request with openlayers<br>From: szekerest@gmail.com<br>To: wingicelee@hotmail.com<br>CC: mapserver-users@lists.osgeo.org<br><br>Hi,<br><br>Currently loadParams can only be called within the context of a CGI process and it may not be usable ny an <a href="http://ASP.NET" target="_blank">ASP.NET</a> application.

Hi, I 'm currently deploying a WFS Server with C# mapscripts. The
Request issued by openlayers is xml-encoded post request.<br>
When I
tried to use "loadparam", it exited abnormally. So I had to parse
parameter by myself. So my question is: do I have to parse the
xml-encoded post request manually?<br>
is there a function I can use to
parse the post request?<br>
