    using Excel = Microsoft.Office.Interop.Excel;

显然，您需要将引用添加到您的项目中，然后就很简单了:)

    private void ProcessExcel(string filepath)
    {

            Excel.ApplicationClass ExcelObj = new Excel.ApplicationClass();

            Excel.Workbook theWorkbook = ExcelObj.Workbooks.Open(filepath, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

            Excel.Sheets sheets = theWorkbook.Worksheets;

            Excel.Worksheet worksheet = (Excel.Worksheet)sheets.get_Item(1);

            Excel.Range range = worksheet.UsedRange;

            System.Array myvalues = (System.Array)range.Cells.Value2;

            int vertical = myvalues.GetLength(0);
            int horizontal = myvalues.GetLength(1);



            string[] headers = new string[horizontal];
            string[] data = new string[horizontal];


            DataTable ResultsHeader = New DataTable();
            DataSet ds = New DataSet();


            for (int x = 1; x <= vertical; x++)
            {
                    Utils.inicializarArrays(datos);
                    for (int y = 1; y <= horizontal; y++)
                    {
                        if (x == 1)
                        {
                            headers[y - 1] = myvalues.GetValue(x, y).ToString();
                        }
