Read Excel file with Epplus

EPPlus is a .net library that reads and writes Excel 2007/2010 files using the Open Office Xml format (xlsx). I use it when I need to read or create Excel files. 

Reading an Excel file:

using (var ms = new MemoryStream(File.ReadAllBytes(filePath)))
{
	using (var package = new ExcelPackage(ms))
	{
		var ws = package.Workbook.Worksheets[1];

		var startRow = ws.Dimension.Start.Row + 1; // first row contains column name/title
		var endRow = ws.Dimension.End.Row;

		for (var i = startRow; i <= endRow; i++)
		{
			if (ws.Cells[i, 1].Value != null)
			{
				personList.Add(new Person()
				{
					FirstName = ws.Cells[i, 1].Value  != null ? Convert.ToInt32(ws.Cells[i, 1].Value) : "N/A",
					LastName = ws.Cells[i, 2].Value != null ? Convert.ToInt32(ws.Cells[i, 2].Value) : "N/A",
					Age = ws.Cells[i, 3].Value  != null ? Convert.ToInt32(ws.Cells[i, 3].Value) : 0;
				});
			}
			else
			{
				break;
			}
		}
	}
}

Just very basic example code. Reading the file in a MemoryStream, which is not really needed. You could also just pass a FileInfo object to the Epplus constructor.

var file = new FileInfo(filePath);
using (var package = new ExcelPackage(file))
{
  // do magic here
}
