                                  barcode.CodeToEncode = line; //"1245718214njgjgkgfhfhnnhkjdshgjkshkgjashjkvjsdhgjkbhkjgjojoweiugfowerjgjuosdruvueijtioeueoiivgtoioewo ctjiosfjojq389594569w4245834589w48fjsdht789437985boui4wuwtr89u34689u3489t4u3tjfydgrtudrjtgwejydrhtseyd5hrjdior7tru6jhyxdgnjlkjbcfmhfhmfxcmgcjkhfhfhf57757456gffbfhfhvhukgyhm0";
                                  

                                 barcode.X = 2;

Surely instead of hardcoding the IMGFULLPATH1, you would

a) generate a value for IMGFULLPATH1 based on the path, a 'template' for the filename - for example
pass in D:\ (path)
pass in template BCode{######}.jpg
b) use something like C# Random String Generator[^] to generate a random string of 6 Characters (that are filename legal) and replace the "######" in the 'template' with the random string
c) check that the random filename doesnt already exist ! if so go back to b
d) return the filename

the filename generator could also just use a sequential number in the place of ###### and/or have a placeholder for the date and time etc

There are also system functions to generate file names - Path.GetTempFileName for example - Im not sure how unique/what restrictions there are on using it

I Found the solution

here

C#

string imageLocation = Server.MapPath(@"~\Images\BCode.jpg");

//The format of the image file
ImageFormat format = ImageFormat.Png;

Bitmap bmp = new Bitmap(960, 386);           //Canvas size
Graphics g = Graphics.FromImage(bmp);
Bitmap origBitmap = new Bitmap(imageLocation);
g.Clear(Color.Transparent); //Background color
// SizeF bc = g.MeasureString(codeInfo, fnt);
Brush br = new SolidBrush(Color.Black);
g.DrawImage(origBitmap, 10, 8);

BarCodeControl barcode = new KeepAutomation.Barcode.Windows.BarCodeControl();
barcode.Symbology = KeepAutomation.Barcode.Symbology.QRCode;

barcode.CodeToEncode = StripLine;


barcode.X = 2;
barcode.Y = 2;
barcode.Width = 200;
barcode.AutoSize = true;
barcode.Height = 2;
barcode.TopMargin = 10;
barcode.BottomMargin = 10;
barcode.LeftMargin = 10;
barcode.RightMargin = 10;
barcode.DisplayText = false;
barcode.DisplayStartStop = true;
barcode.BarcodeUnit = KeepAutomation.Barcode.BarcodeUnit.Pixel;
barcode.ImageFormat = ImageFormat.Bmp;

//path of unique file name
string path = string.Format("{0}{1}.png", @"D:\BarCodeIMG\", codeInfo);------------(You can here pass value from text box or other control)
barcode.SaveAsImage(path);
