I’m having a little problem with my code... is eating a Braba memory... and is not pouring memory ... a simple application within my program... Label printing... every time I print a label the code takes the ID and generates a QR on the label... but it’s eating a lot of memory and I’m not getting to dump it ... any tips ? follows the Cod...
using MessagingToolkit.QRCode.Codec;
using System.Drawing;
using System.IO;
public class QRCode
{
//guarda imagem QR em byte[]
public static byte[] imgQR { get; set; }
public static bool GerarQR(Invoices Invoice)
{
//tenta gerar o QR
try
{
QRCodeEncoder qrCodecEncoder = new QRCodeEncoder();
qrCodecEncoder.QRCodeBackgroundColor = System.Drawing.Color.White;
qrCodecEncoder.QRCodeForegroundColor = System.Drawing.Color.Black;
qrCodecEncoder.CharacterSet = "UTF-8";
qrCodecEncoder.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE;
qrCodecEncoder.QRCodeScale = 6;
qrCodecEncoder.QRCodeVersion = 0;
qrCodecEncoder.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.Q;
Image imageQRCode;
//string a ser gerada
string data = "Invoice: " + Invoice.InvoicesID.ToString(); // QR gerado pelo ID do Invoice
imageQRCode = qrCodecEncoder.Encode(data);
//converte a imagem QR em byte[]
MemoryStream ms = new MemoryStream();
imageQRCode.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
imgQR = ms.ToArray();
ms.Dispose();
return true;
}
catch
{
return false;
}
}
}
Here is the imprint that calls the class to generate the QR

PS I’m guessing is my DLL...
Mediu? are you sure this is the part that is consuming memory? Do you think the impression is causing or the generation? The
QRCodeEncoderallocates resources? Are you generating an exception? This code really doesn’t look robust to handle problems. There are cases where consumption is normal.– Maniero
every time I ask to print the label it will allocate memory and not pour after printing... and it will grow causing locking... when I use for 1 or 2 labels there is no difference anymore when it comes out 1000 labels at once the memory craves an absurd... I made a test printing 10, 10, 10,10,10,10,10,10,10,10,10 and the memory is unstable... more when I ask to print 1000 at once it bursts... no exception appears... more I see in the debug eating the memory

I was able to solve it... when I had many labels printed at once, it burst in my memory... but when I asked him to print it again, he cleaned the memory cache so he could use it for a new batch of prints...

Something tells me this is not a good solution, whatever it is, for me it doesn’t even answer the question.
