QuickGetBd Example

The QuickGetBd method is called to send a GET request to download a binary target, such as PDF, zip, image file, etc. into a Chilkat BinData object. C#

bool success = false;

//  This example assumes the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();
http.KeepResponseBody = true;

Chilkat.BinData bd = new Chilkat.BinData();

//  Download the contents of a PDF file into the bd object.
success = http.QuickGetBd("https://www.chilkatsoft.com/hello.pdf",bd);
if (success == false) {
    //  This will happen if the response status code was 400 or greater,
    //  or if the request could not be sent, or if no response was received.
    //  
    //  In other words, success will only be true if bd contains the desired content at the URL (not an error response).
    int statusCode = http.LastStatus;
    Debug.WriteLine("Response status: " + Convert.ToString(statusCode));

    if (statusCode == 0) {
        //  There was an error in communications.  
        Debug.WriteLine(http.LastErrorText);
    }
    else {
        //  We received a response status code indicating failure.
        //  Examine the response body.
        Debug.WriteLine(http.LastResponseBody);
    }

    return;
}

//  Load the downloaded PDF into a Chilkat PDF object.
Chilkat.Pdf pdf = new Chilkat.Pdf();
success = pdf.LoadBd(bd);
if (success == false) {
    Debug.WriteLine(pdf.LastErrorText);
    return;
}

//  ...

Debug.WriteLine("Success.");
