First of all EPPlus can not handle .xls files. See this answer:

Error when trying to read an .xls file using EPPlus

Sample code for reading a file:

var package = new ExcelPackage(new FileInfo("sample.xlsx"));

ExcelWorksheet workSheet = package.Workbook.Worksheets.FirstOrDefault();

for (int i = workSheet.Dimension.Start.Column;
        i <= workSheet.Dimension.End.Column;
        i++)
{
    for (int j = workSheet.Dimension.Start.Row;
            j <= workSheet.Dimension.End.Row;
            j++)
    {
        object cellValue = workSheet.Cells[i, j].Value;
    }
}
