AlliterativeAlice s example helped me tremendously  In my case  though  the server I was talking to didn t like having single quotes around utf-8 in the content type  It failed with a generic  Server Error  and it took hours to figure out what it didn t like   request ContentType    text xml  encoding utf-8

In General   An example of an easy way to post XML data and get the response  as a string  would be the following function   public string postXMLData string destinationUrl  string requestXml        HttpWebRequest request    HttpWebRequest WebRequest Create destinationUrl       byte   bytes      bytes   System Text Encoding ASCII GetBytes requestXml       request ContentType    text xml  encoding  utf-8        request ContentLength   bytes Length      request Method    POST       Stream requestStream   request GetRequestStream        requestStream Write bytes  0  bytes Length       requestStream Close        HttpWebResponse response      response    HttpWebResponse request GetResponse        if  response StatusCode    HttpStatusCode OK                Stream responseStream   response GetResponseStream            string responseStr   new StreamReader responseStream  ReadToEnd            return responseStr            return null      In your specific situation   Instead of   request ContentType    application x-www-form-urlencoded     use   request ContentType    text xml  encoding  utf-8      Also  remove   string postData    XMLData     Sendingxml    And replace   byte   byteArray   Encoding UTF8 GetBytes postData     with   byte   byteArray   Encoding UTF8 GetBytes Sendingxml ToString
