AlexMedina.Edi 1.12.0

AlexMedina.Edi

EDI Serializer/Deserializer. Used to read & write EDI streams.

This is a ground up implementation and does not make use of XML Serialization in any step of the process. This reduces the overhead of converting into multiple formats allong the way of getting the desired Clr object. This makes the process quite fast.

Tested with Tradacoms, EDIFact and ANSI ASC X12 (X12) formats.

Using attributes you can express all EDI rules like Mandatory/Conditional Segments, Elements & Components as well as describe component values size length and precision with the picture syntax (e.g 9(3), 9(10)V9(2) and X(3)).

Installation

To install Edi.Net, run the following command in the Package Manager Console. Or download it here

PM> Install-Package "AlexMedina.Edi"

Attributes.

The general rules of thumb are :

Example usage:

There are available configurations (EdiGrammar) for EDIFact, Tradacoms and X12. Working examples for all supported EDI formats can be found in the source code under tests.

• EdiFact sample POCO classes
• TRADACOMS sample classes (UtilityBill)
• X12 sample classes (850 Purchase Order)

Note that all examples may be partialy implemented transmissions for demonstration purposes although they are a good starting point. If someone has complete poco classes for any transmition please feel free to contribute a complete test.

Deserialization (EDI to POCOs)

The following example makes use of the Tradacoms grammar and deserializes the sample.edi file to the Interchange class.

var grammar = EdiGrammar.NewTradacoms();
var interchange = default(Interchange);
using (var stream = new StreamReader(@"c:\temp\sample.edi")) {
    interchange = new EdiSerializer().Deserialize<Interchange>(stream, grammar);
}

Serialization (POCOs to EDI)

In this case we are instantiating our POCO class Interchange and then fill-it up with values before finally serializing to out.edi.

var grammar = EdiGrammar.NewTradacoms();
var interchange = new Interchange();
// fill properies 
interchange.TransmissionDate = DateTime.Now;
...
// serialize to file.
using (var textWriter = new StreamWriter(File.Open(@"c:\temp\out.edi", FileMode.Create))) {
    using (var ediWriter = new EdiTextWriter(textWriter, grammar)) { 
        new EdiSerializer().Serialize(ediWriter, interchange);
    }
}

Model

Annotated POCOS example using part of Tradacoms UtilityBill format:

    public string SenderCode { get; set; }

    [EdiValue("X(35)", Path = "STX/1/1")]

Build the sourcecode

As of v1.0.7 the solution was adapted to support the dotnet core project system. Then it was adapted again since the dotnet core tooling was officialy relased (March 7th 2017 at the launch of Visual studio 2017). In order to build and test the source code you will need either one of the following.

• Visual studio 2017 + the dotnet core workload (for v1.1.3 onwards)
• Visual studio 2015 Update 3 & .NET Core 1.0.0 - VS 2015 Tooling (for versions v1.0.7 - v1.1.2)
• VS Code + .NET Core SDK

for more information check .Net Core official page.

The Picture clause

The Picture Clause is taken from COBOL laguage and the way it handles expressing numeric and alphanumric data types. It is used throughout tradacoms.
