How to convert barcode to image using C# and VB.NET
Syncfusion Essential Barcode control is used to create various types of barcodes. Using this control, you can export barcode as image without GUI interfaces using C# and VB.NET.
Steps to export barcode as image programmatically:
- Create a new C# Windows Forms application project.
- Install the Syncfusion.SfBarcode.Windows NuGet package as reference to your .NET Framework application from NuGet.org.
- Include the following namespaces in the Form1.Designer.cs file.
C#
using Syncfusion.Windows.Forms.Barcode; using System.Drawing;
VB.NET
Imports Syncfusion.Windows.Forms.Barcode Imports System.Drawing
- Use the following code snippet to export barcode to image without using any GUI interfaces.
C#
//Create a new Barcode control
SfBarcode barcode = new SfBarcode();
//Set the barcode text
barcode.Text = "Syncfusion Essential Studio Enterprise edition $995";
//Set the barcode type
barcode.Symbology = BarcodeSymbolType.QRBarcode;
//Set dimension for each block
QRBarcodeSetting setting = new QRBarcodeSetting();
setting.XDimension = 6;
barcode.SymbologySettings = setting;
//Export to image
Image img = barcode.ToImage();
//Save the image
img.Save("QRBarcode.png", System.Drawing.Imaging.ImageFormat.Png);
//Dispose the control
barcode.Dispose();
VB.NET
'Create a new Barcode control
Dim barcode As SfBarcode = New SfBarcode()
'Set the barcode text
barcode.Text = "Syncfusion Essential Studio Enterprise edition $995"
'Set the barcode type
barcode.Symbology = BarcodeSymbolType.QRBarcode
Dim setting As QRBarcodeSetting = New QRBarcodeSetting()
setting.XDimension = 6
barcode.SymbologySettings = setting
Dim img As Image = barcode.ToImage()
'Save the image
img.Save("QRBarcode.png", System.Drawing.Imaging.ImageFormat.Png)
'Dispose the control
barcode.Dispose()
Process.Start("QRBarcode.png")
