wpf - Upload jpeg encoded bitmap to server with httpwebrequest -

i've been trying upload image (jpeg formatted) server. i've used different approaches, none of them worked.

approach 1

i've tried saving jpeg data directly httpwebrequest stream:

//create bitmap. bitmapimage^ bm = gcnew bitmapimage(gcnew uri(path, urikind::relative));  /*     stuff bitmap. */  //create jpeg. jpegbitmapencoder enc; enc.frames->add(bitmapframe::create(bm));  //prepare web request. httpwebrequest^ request = dynamic_cast<httpwebrequest^>(webrequest::create(l"http://localhost")); request->contenttype = "image/jpeg"; request->method = "put";  //prepare web request content. stream^ s = request->getrequeststream(); enc.save(s);//throws 'system.notsupportedexception'. s->close(); 

writing httpwebrequest stream doesn't work, when tested filestream, perfect image created.

approach 2

i tried saving jpeg data memorystream , copying httpwebrequest stream:

//create bitmap. bitmapimage^ bm = gcnew bitmapimage(gcnew uri(path, urikind::relative));  /*     stuff bitmap. */  //create jpeg. memorystream^ ms = gcnew memorystream; jpegbitmapencoder enc; enc.frames->add(bitmapframe::create(bm)); enc.save(ms);  //prepare web request. httpwebrequest^ request = dynamic_cast<httpwebrequest^>(webrequest::create(l"http://localhost")); request->contenttype = "image/jpeg"; request->method = "put";  //prepare web request content. stream^ s = request->getrequeststream(); int read; array<byte>^ buffer = gcnew array<byte>(10000); while((read = ms->read(buffer, 0, buffer->length)) > 0)//doesn't read bytes.     s->write(buffer, 0, read);  s->close(); ms->close(); 

can tell me i'm doing wrong or give me alternative?

thank you.

insert before while loop:

ms->seek(0, seekorigin.begin); 

the problem starting read end of stream... doh!
