bool success;
Chilkat.Http http = new Chilkat.Http();

//  Any string unlocks the component for the 1st 30-days.
success = http.UnlockComponent("Anything for 30-day trial");
if (success != true) {
    MessageBox.Show(http.LastErrorText);
    return;
}

//  Build a HTTPS upload request with the files to be uploaded:
Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.UseUpload();

//  The URL we'll be posting to is:
//  http://www.yourwebserver123abc.com/ConsumeUpload.aspx
//  Therefore, the path part of the URL is:
req.Path = "/ConsumeUpload.aspx";

//  Note: You'll need to edit this example to upload to your
//  own web server.

//  Add some files to the request:
//  The 1st argument is an arbitrary name.  It's the POST form field name.
//  The 2nd argument is the filename currently existing on
//  the local filesystem.  It may include an absolute or relative
//  path, or no path at all if it's in the current working directory.
success = req.AddFileForUpload("file1","hamlet.xml");
if (success != true) {
    MessageBox.Show(req.LastErrorText);
    return;
}

success = req.AddFileForUpload("file2","dude.gif");
if (success != true) {
    MessageBox.Show(req.LastErrorText);
    return;
}

//  Send the HTTPS POST and get the response.  Note: This is a blocking call.
//  The method does not return until the full HTTPS response is received.
string domain;
int port;
bool ssl;
domain = "www.yourwebserver123abc.com";
//  The only difference in coding between non-SSL and SSL is
//  the setting of these two arguments to SynchronousRequest:
port = 443;
ssl = true;
Chilkat.HttpResponse resp = null;
resp = http.SynchronousRequest(domain,port,ssl,req);
if (resp == null ) {
    textBox1.Text += http.LastErrorText + "\r\n";
    textBox1.Refresh();
}
else {
    //  Display the HTML source of the page returned.
    textBox1.Text += resp.BodyStr + "\r\n";
    textBox1.Refresh();
}
