xamarin.ios - call webservice using NSMutableURLRequest in monotouch -

i try save capture image iphone server. done xcode. code like

nsmutableurlrequest  *request= [nsmutableurlrequest requestwithurl:url];  [request sethttpmethod:@"post"];  nsstring *boundary = @"---------------------------14737809831466499882746641449";  nsstring *contenttype = [nsstring stringwithformat:@"multipart/form-data; boundary=%@",boundary];  [request addvalue:contenttype forhttpheaderfield: @"content-type"];  nsmutabledata *body = [nsmutabledata data];  [body appenddata:[[nsstring stringwithformat:@"--%@\r\n", boundary] datausingencoding:nsutf8stringencoding]]; [body appenddata:[[nsstring stringwithformat:@"content-disposition: attachment; name=\"%@\" filename=\"test.png\"\r\n", imgname] datausingencoding:nsutf8stringencoding]];  [body appenddata:[@"content-type: application/octet-stream\r\n\r\n" datausingencoding:nsutf8stringencoding]]; [body appenddata:[nsdata datawithdata:imagedata]]; [body appenddata:[@"\r\n" datausingencoding:nsutf8stringencoding]];  [request sethttpbody:body];  nsurlconnection *theconnection = [[nsurlconnection alloc] initwithrequest:request delegate:delegate]; 

now try monotouch,

here create connection, send request & receive response working fine.

but here don't know how set header & body nsmutableurlrequest, need know how pass parameters (like above xcode).

nsmutableurlrequest request = new nsmutableurlrequest(new nsurl("http://url.com"), nsurlrequestcachepolicy.reloadrevalidatingcachedata, 20); request.httpmethod = "post";  var connectiondelegate = new testnsurlconnectiondelegate(); var connection = new nsurlconnection(request, connectiondelegate); connection.start(); 

can 1 me this...

using system.net access httpwebrequest.

you have post url.. , write byte[] of image body of request.

in example.. servicebase value maps static string, , "service.submitimage" static string pointing service method endpoint.

 public void submitimage(byte[] image)     {         var request = webrequest.create(servicebase + service.submitimage);         request.method = "post";         request.contenttype = "application/octet-stream";         request.contentlength = image.length;         stream str = request.getrequeststream();         str.write(image, 0, image.length);         str.close();         httpwebresponse response = (httpwebresponse)request.getresponse();     }
