Problems POSTing data to an asp.net webpage (problem in Desktop C# end) -

thank taking time read post! having problem posting data c# desktop application c# asp.net web page. believe problem lies in desktop application (or @ least 1 of problems does!) post asp.net code using. if asp.net not speciality, don't worry, wondering if there glaringly obvious there well.

i had create asp.net website post data windows forms application. working perfectly.

here code using. not working discussed below. bad @ asp.net stuff, can provide appreciated.

if (system.net.networkinformation.networkinterface.getisnetworkavailable() && result == dialogresult.yes)             {                 string test = "test";                 webrequest request = webrequest.create("http://localhost/test.aspx");                 byte[] bytearray = encoding.utf8.getbytes(test);                  request.method = "post";                 request.contenttype = "application/x-www-form-urlencoded";                 request.contentlength = bytearray.length;                  // give response                 using (stream datastream = request.getrequeststream())                 {                     datastream.write(bytearray, 0, bytearray.length);                 }              } 

however, when debug application, , put breakpoint after datastream.write() errors in variable watch window. not exceptions except in there.

i cannot upload image website seems, shall upload freewebs site - sorry, embarrassing! watch.jpg

as can see, getting system.notsupported on datastream.length , datastream.position

could please me fix this? thanks!

just in case asp.net programmer sees this, there problem receiving code?:

    protected void page_load(object sender, eventargs e)     {         string test = request.binaryread(request.totalbytes).tostring();     } 

thank all, so, time!

edit: in relation gandjustas's comment, providing more information.

something in chain not working. not getting formal exceptions report.

if use code in asp.net webpage:

 string test = request.binaryread(request.totalbytes).tostring();          response.clear();         response.write(test);         response.end(); 

i following response back: system.byte[]

this not variable, string containing arbitrary words , symbols 'system.byte[]'

something not working (obviously) see system.notsupportedexception in watch window. make me think there 2 errors: system.notsupportedexception needs fixing in c# desktop application, , asp.net webpage should not displaying system.byte[] before have sent post application.

i kind of need help. thanks!

couple of remarks code:

1. you setting application/x-www-form-urlencoded content type sending arbitrary byte array. when set content type server expect request encoded using it.
2. the notsupportedexception getting in debug window normal. cannot use length property on networkstream.

let me try simplify code in case want use application/x-www-form-urlencoded:

client:

using (var client = new webclient()) {     var values = new namevaluecollection     {         { "key1", "value1" },         { "key2", "value2" },     };     byte[] result = client.uploadvalues("http://example.com/test.aspx", values); } 

server:

protected void page_load(object sender, eventargs e) {     string key1 = request["key1"];     string key2 = request["key2"]; }
