xml - Why is MemoryStream limited to 6KB of data? -

-

i have xml document, 7,917 characters. it's read xelement using linq xml, need map/convert/adapt xelement string (to send web service).

here method:

    public string adaptxelementtostring(xelement xml)     {         encoding encoding = encoding.getencoding(specializedencodings.iso88591);          using (memorystream memorystream = new memorystream())         {             xmlwritersettings settings = new xmlwritersettings { encoding = encoding };              memorystream.setlength(21*1024*1024);              using (xmlwriter writer = xmlwriter.create(memorystream, settings))             {                 xml.writeto(writer);                 memorystream.flush();                  string xmltext = encoding.getstring(memorystream.toarray());                 return xmltext;             }         }     }

when call method, can see using intellisense 'xml' has entire contents of file. however, string xmltext gets chopped off @ 6144th character (which 6 kb exactly). because xmltext getting chopping off, i'm losing 1773 characters.

does know why method isn't returning entire string? set length of memory stream buffer 21 mb ensure it's big enough (even though default constructor supports resizing).

i same behavior if remove call setlength(). same behavior if remove call flush().

for purposes, must use encoding iso-8859-1, can't change utf-8 or 16.

any appreciated!

solved problem:

use writer.flush(); not memorystream.flush()

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
