HTTP Upload in C#

C# example showing how to upload one or more files to an HTTP server.

Chilkat.Http http = new Chilkat.Http();
bool unlocked = http.UnlockComponent("Any string begins 30-day trial");
if (!unlocked)
{
    MessageBox.Show("Failed to unlock HTTP component");
    return;
}

// Create an HTTP request for file upload.
Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.UseUpload();
req.Path = "/freeaspupload/testUpload.asp";

// Call AddFileForUpload 1 or more times to upload any number of files at once.
string name = "File1";
string localFilename = "dude.gif";
req.AddFileForUpload(name,localFilename);

name = "File2";
localFilename = "dudeActiveX.gif";
req.AddFileForUpload(name,localFilename);

// Upload the files by calling SynchronousRequest.		
bool ssl = false;   // Set this to true to use HTTPS
Chilkat.HttpResponse resp = http.SynchronousRequest("www.freeaspupload.net",80,false,req);
if (resp == null) 
{
    MessageBox.Show(http.LastErrorText);
    return;
}

// Did we get a successful response?
if (resp.StatusCode == 200)
{
    // Success!
    // Display the response status line, header and body
    MessageBox.Show(resp.StatusLine + "\r\n" + resp.Header);
    textBox6.Text = resp.BodyStr;		    
}
else
{
    // Failed!  (Take the same action as for success in this example.)
    // Display the response status line, header and body
    MessageBox.Show(resp.StatusLine + "\r\n" + resp.Header);
    textBox6.Text = resp.BodyStr;
}
