What is Exportable?

Exportable is a component for .NET, 100% open source, with MIT license; builded on top of NPOI. In the future, are plans to handle other formats, like CSV, Json, and others.

1. Changes in version 2.0

• Version 2.0 has a shorter namespace, from Infodinamica.Framework.Exportable to Exportable
• Version 2.0 don't requieres set the Key parameter in AddContainer method
• Version 2.0 support ignore and rename columns on runtime
• Version 2.0 don't use Infodinamica.Framework.Core
• Version 2.0 use the latest stable NPOI release (2.3.0)

2. Installation with NUGET

Install-Package Infodinamica.Framework.Exportable

3. Requirements

The version 2.+, requires .NET Framework 4.5.0. Version 1.* requires .NET Framework 3.5.

4. Namespaces

These are the commonly namespace required's to export and import:

using Exportable.Engines;
using Exportable.Engines.Excel;

5. Export

5.1. Simple Export

IList<DummyPerson> dummyPeople = new List<DummyPerson>();
//Add data to dummyPeople...
IExportEngine engine = new ExcelExportEngine();
engine.AddData(dummyPeople); 
MemoryStream memory = engine.Export();

5.2. Specifying the Excel version

IList<DummyPerson> dummyPeople = new List<DummyPerson>();
//Add data to dummyPeople...
IExcelExportEngine engine = new ExcelExportEngine();
engine.SetFormat(ExcelVersion.XLS);
engine.AddData(dummyPeople); 
MemoryStream memory = engine.Export();

5.3. Set columns name's, order and format

5.3.1. First, add this using

using Exportable.Attribute;

5.3.2. Second, set "Exportable" attributes

public class DummyPerson
{   
    [Exportable(3, "Full Name", FieldValueType.Text)]  
    public string Name { get; set; }
    
    [Exportable(1, "Birth Date", FieldValueType.Date, "MM-yyyy")]   
    public DateTime BirthDate { get; set; } 
    
    [Exportable(2, "How Many Years", FieldValueType.Numeric, "#0")]   
    public int Age { get; set; }
    
    [Exportable(4, "Is Adult", FieldValueType.Bool)]    
    public bool IsAdult { get; set; }  
    
    [Exportable(IsIgnored = true)]
    public string ThisColumnWillBeIgnored { get; set; }
}

5.4. Override column names

You can override the column name with AddColumnsNames method. You need a plain class (in this case DummyPersonWithAttributes) and specify the new column name. Please note that this configuration overrides the column name specified in the class attribute

IExportEngine engine = new ExcelExportEngine();
var key = engine.AddData(dummyPeople);
engine.AddColumnsNames<DummyPersonWithAttributes>(key, x => x.Name, "this is a new name LOL!");
var stream = engine.Export();

5.5. Ignore column names on runtime

You can ignore columns with AddIgnoreColumns method. You need a plain class (in this case DummyPersonWithAttributes) and specify the column that you want to ignore. Please note that this configuration overrides the column ignore specified in the class attribute

IExportEngine engine = new ExcelExportEngine();
var key = engine.AddData(dummyPeople);
engine.AddIgnoreColumns<DummyPersonWithAttributes>(key, x => x.Name);
var stream = engine.Export();

5.6. Specify a column name by resource

You can handle internationalization column names, by using resources in attributes. Please note that ResouceType property, has a pointer to resource file, while HeaderName property has the key of the resource

5.6.1. Plain class

class DummyPersonWithAttributesAndResource
{
    [Exportable(Position = 0, HeaderName = "Header1", ResourceType = typeof(res), TypeValue = FieldValueType.Text)]
    public string Name { get; set; }

    [Exportable(1, "Header2", FieldValueType.Date, "MM-yyyy", ResourceType = typeof(res))]
    public DateTime BirthDate { get; set; }

    [Exportable(IsIgnored = true)]
    public int Age { get; set; }

    [Exportable(3, "Is Adult", FieldValueType.Bool)]
    public bool IsAdult { get; set; }
}

5.6.2. Resource

Name	Value
Header1	Column 1
Header2	Column 2

6. Import

6.1 Simple Import

IImportEngine engine = new ExcelImportEngine();
var key = engine.AddContainer<DummyPersonWithAttributes>();
engine.SetDocument(pathToFile); //or MemoryStream instance
var data = engine.GetList<DummyPersonWithAttributes>(key);

6.1 Specify Excel version

IImportEngine engine = new ExcelImportEngine();
engine.AsExcel().SetFormat(ExcelVersion.XLS);
var key = engine.AddContainer<DummyPersonWithAttributes>();
engine.SetDocument(pathToFile); //or MemoryStream instance
var data = engine.GetList<DummyPersonWithAttributes>(key);
