Create Leitcode using Console Application Template
Visual Studio Visual C# Console Application TemplateThere are a number of Project Templates that is shipped by Visual Studio. Console Application Template is one of them.
Console Application Template is designed to develop console applications.
Console Application is a computer project that is used by Textual Interface. Unlike Graphical User Interface (GUI), Text-Only Interface displays a command prompt, and accepts textual character strings which is also called command line. Command line could be validated, interpreted, and parameter-expanded by the interface before being executed.
Console Application Template automatically adds essential project reference as well as .NET Identcode Generator reference to your console Application. The console Application inherits .NET Identcode Generator functionality and console application features.

Leitcode Background InformationLeitcode is a numeric barcode symbology that is used by the Deutsche Post AG. It primarily uses the code from one to nine. This code is based on Code Interleaved 2 of 5, but with a different check digit. It is pretty much the same thing with Identcode which is also a variant of Code Interleaved 2 of 5.
Overview of Interleaved 2 of 5Interleaved 2 of 5 is a highly-densified numeric symbology encoding digits. Based upon the industrial 2 of 5 symbology, it is a continuous two-width barcode and used on some cartoon products and on 135 film commercially. While the products inside are often labeled with UPC or EAN. Besides, it is also called ANSI, AIM ITF 25, ITF, USS ITF2/5, Uniform Symbology Specification IFT, and 2/5 Interleaved.
CharacteristicsOverall, Interleaved 2 of 5 is fit for encoding general purpose all-numeric, and most importantly, it is utilized mainly in the distribution and warehouse industry. Undoubtedly, Interleaved 2 of 5 has many things in common with Industrial 2 of 5 except for the fact that Code 2 of 5 only encodes information in the bars while Interleaved 2 of 5 can encode information in both the bars and spaces. However, the encoding scheme is suitable for both in terms of their use of wide and narrow elements for each component.
EncodingPairs of digits can be encoded by Interleaved 2 of 5. The first digit is encoded in the five bars which can also be called black lines while the second digit is encoded in the five spaces which are also known as white lines, which means the white lines interleave with the black lines.
"N" is a narrow line and "w" is a wide line. A 2 of 5 code can be formed by the wide lines with the consecutive values of 1, 2, 4, 7 and 0. Here the code 0 has the value of 11, which is pretty much like the POSTNET barcode.
A start code made up of nnnn which means narrow bar-narrow space-narrow bar-narrow space can be seen before the real pairs, and after all symbols, there is the stop code including Wnn which refers to Wide bar-narrow space-narrow bar.
Normally, if we want to encode an odd number of digits, we will add a "0" as first digit. Sometimes an odd number of digits is encoded by using five narrow spaces in the last digit. Therefore, a checksum can be added as last digit, which can be computed in the same way as UPC checksums.
