.NET Barcode Postnet Generator Introduction
Top
Generating Barcode Postnet in .NET is one of the functions in OnBarcode's .NET Barcode Generators, which supports creating & printing Postnet and 30+ other linear & 2D bar codes for C#, VB.NET & ASP.NET applications.
OnBarcode develops several .NET Barcode Generation components for different .NET development environments:

.NET Postnet Generator - Barcode Postnet Introduction

POSTNET (Postal Numeric Encoding Technique), also known as USPS POSTNET Barcode, USPS POSTal Numeric Encoding Technique Barcode, is a barcode symbology that is used by the United States Postal Service to assist in directing mail. The ZIP Code or ZIP+4 code is encoded in half- and full-height bars.

.NET Postnet Generation - Postnet Valid Data Scope

.NET Postnet Generator encodes:
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

How to Generate & Print POSTNET in Visual Studio C# or VB.NET Class?
Top
Generating barcode POSTNET in C# Class example (C# POSTNET Generator Complete Demo Source Code):
   Linear postnet = new Linear();
   postnet.Type = BarcodeType.POSTNET;
   postnet.Data = "12345";
   postnet.X = 1;
   postnet.Y = 60;
	        
   // Generate Postnet and encode barcode to gif format
   postnet.Format = System.Drawing.Imaging.ImageFormat.Gif;
   postnet.drawBarcode("C://c#-postnet.gif");
	        
   // Print Postnet to C# Bitmap object
   Bitmap postnetBitmap = postnet.drawBarcode();
Generating barcode POSTNET in VB.NET Class example (VB.NET POSTNET Generator Complete Demo Source Code):
   Dim postnet As OnBarcode.Barcode.Linear
   postnet = New OnBarcode.Barcode.Linear()
   postnet.Type = OnBarcode.Barcode.BarcodeType.POSTNET
   postnet.Data = "123456789"
   postnet.X = 1
   postnet.Y = 60
	        
   ' Generate Postnet and encode barcode to png format
   postnet.Format = System.Drawing.Imaging.ImageFormat.Png
   postnet.drawBarcode("C://vbnet-postnet.png")
	        
   ' Print Postnet to vb.net Bitmap object
   Dim postnetBitmap As Bitmap
   postnetBitmap = postnet.drawBarcode()
How to Create & Draw Postnet Image in ASP.NET aspx or Html Pages Without ASP.NET Barcode Controller?
Top
  • Under demo package, copy barcode folder and its contents to your IIS, and create a new virtual directory.
  • Restart IIS, navigate to http://YourDomain:Port/barcode/linear.aspx?DATA=01234&TYPE=34.
  • To create barcode Postnet image in html or aspx pages, you can insert a image tag (img) into your page.
    For example, <img src="http://YourDomain:Port/barcode/linear.aspx?DATA=01234&TYPE=34" />
How to Create & Encode Barcode Postnet to Image File (GIF, JPEG, PNG, BMP)?
Top
Creating barcode Postnet in C# Class example:
   Linear postnet = new Linear();
   postnet.Type = BarcodeType.POSTNET;
   postnet.Data = "98765";

   // Generate POSTNET and encode barcode to bmp format
   postnet.Format = System.Drawing.Imaging.ImageFormat.Bmp;
   postnet.drawBarcode("C://c#-postnet.bmp");
Creating barcode Postnet in VB.NET Class example:
   Dim postnet As OnBarcode.Barcode.Linear
   postnet = New OnBarcode.Barcode.Linear()
   postnet.Type = OnBarcode.Barcode.BarcodeType.POSTNET
   postnet.Data = "987654321"

   ' Generate POSTNET and encode barcode to jpg format
   postnet.Format = System.Drawing.Imaging.ImageFormat.Jpeg
   postnet.drawBarcode("C://vbnet-postnet.jpg")
In Visual Studio C# & VB.NET, How to Draw & Print Barcode Postnet to .NET Graphics, Stream & Bitmap Objects?
Top
Creating barcode Postnet in C# Class example:
   public void drawBarcode(Graphics graphics);
	
   public void drawBarcode(string filename);
	
   public Bitmap drawBarcode();
	
   public void drawBarcode(Stream fileStream);
To draw & print barcode Postnet to VB.NET objects:
   Public Sub drawBarcode(ByRef graphics As Graphics)
	
   Public Sub drawBarcode(ByVal filename As String)
	
   Public Function drawBarcode() As Bitmap
	
   Public Sub drawBarcode(ByRef fileStream As Stream)
