Lith.FlatFile

This library makes it easier to consume and create flat files through tight coupling between POCO and the source or destination data.

Features

• The specification for every file lives within it's class/model.
• (De)Serialize most data-types including enums.
• Objects just needs to implement the IFlatObject interface to enable usage.

How to use Lith.FlatFile

1. Install this package ($ install-package Lith.FlatFile)
2. Create a POCO for your file. See 'Setting up a POCO.'
3. Read flatfile data via the LineBreaker class.
4. Write flatfile data via the LineBuilder class.

Setting up a POCO

	/// This is required by the IFlatObject

	public DumbEnum ChosenOption { get; set; }
