How to Generate a Barcode using C#

Generating a barcode with the Aspose Plugin is both straightforward and efficient. Follow these steps to create a barcode using C#, utilizing Barcode Generator C# Source Code:

  1. Instantiate the BarcodeGenerator class, specifying the desired barcode type and text in the constructor.
  2. Configure the barcode’s features, such as resolution and size.
  3. Generate the barcode using the BarcodeGenerator.Save(String) method.

Here’s a code sample demonstrating how to generate a barcode using Barcode C# SDK:

BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.Code128, "Aspose.BarCode");
// set resolution
generator.Parameters.Resolution = 400;
// generate barcode
generator.Save("generate-barcode.png");

How to Generate a QR Barcode using C#

Creating a QR barcode follows a similar process to generating other barcode types. Here’s how to do it:

  1. Instantiate the BarcodeGenerator class, specifying the barcode type as EncodeTypes.QR.
  2. Generate the barcode using the BarcodeGenerator.Save(String) method.

Here’s a code sample for generating a QR barcode using C#:

BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.QR, "Aspose.BarCode");
// set resolution
generator.Parameters.Resolution = 400;
// generate barcode
generator.Save("generate-barcode.png");

Customize the Appearance of a Barcode in C#

Customizing the appearance of a barcode is easy with the Aspose Plugin. You can modify its font, foreground color, background color, and text color. Here are the steps:

  1. Instantiate the BarcodeGenerator class.
  2. Adjust the barcode’s appearance using the BarcodeGenerator.Parameters properties, such as BarcodeGenerator.Parameters.BackColor.
  3. Generate the barcode using the BarcodeGenerator.Save(String).

Here’s a code sample for generating a customized Aztec barcode using Barcode Generator C#:

BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.Aztec, "Aspose.BarCode");
// set barcode's back color
generator.Parameters.BackColor = System.Drawing.Color.DarkGray;
// set barcode's bar color
generator.Parameters.Barcode.BarColor = System.Drawing.Color.Orange;
// set border color
generator.Parameters.Border.Color = System.Drawing.Color.Black;
// set text color
generator.Parameters.Barcode.CodeTextParameters.Color = System.Drawing.Color.Orange;
// set resolution
generator.Parameters.Resolution = 400;
// generate barcode
generator.Save("generate-barcode.png");

Add Caption in Barcodes using C#

Incorporating captions into barcodes can provide additional context, and the Aspose Plugin makes this process seamless. Here’s how to add a caption:

  1. Instantiate the BarcodeGenerator class.
  2. Set the barcode’s text and type in the constructor of BarcodeGenerator.
  3. Utilize the CaptionAbove or CaptionBelow properties to configure the caption.
  4. Save the barcode using the BarcodeGenerator.Save(String) method.

Here’s a code sample for adding a caption to a barcode using Barcode Generator C#:

BarcodeGenerator generator = new BarcodeGenerator(EncodeTypes.Code128, "Aspose.BarCode");
// set captions
generator.Parameters.CaptionAbove.Text = "The caption above.";
generator.Parameters.CaptionAbove.Visible = true;
generator.Parameters.CaptionBelow.Text = "The caption below.";
generator.Parameters.CaptionBelow.Visible = true;
// generate barcode
generator.Save("generate-barcode.png");
