Code 128 Image Setting in C#.NET and VB.NET Class Library
Copy the C#/ VB.NET barcode syntax to projects to produce, display a Code 128 barcodes in .NET Windows Forms:
using KeepAutomation.Barcode.Bean;
BarCode code128= new BarCode();
code128. Symbology = Symbology. Code128Auto;
code128.CodeToEncode = "Code128";
code128.BarcodeUnit = BarcodeUnit.Pixel;
code128.DPI = 72;
code128.X =2;
code128.LeftMargin = 3;
code128.RightMargin = 3;
code128.TopMargin = 3;
code128.BottomMargin = 3;
code128.Orientation = KeepAutomation.Barcode.Orientation .Degree90
code128.ImageFormat = System.Drawing.Imaging.ImageFormat.Png;
Dim code128 As KeepAutomation.Barcode.Bean.BarCode = New KeepAutomation.Barcode.Bean.BarCode

code128.Symbology = KeepAutomation.Barcode.Symbology.Code128Auto
code128.BarcodeUnit = BarcodeUnit.Pixel
