我在下面使用此代码：

    private void Form1_Load(object sender, EventArgs e)
    {
        DataSet ds = new DataSet();
        DataTable dt = new DataTable();
        dt.Columns.Add("Name");
        dt.Columns.Add("Country");
        dt.Rows.Add("Venkatesh", "India");
        dt.Rows.Add("Santhosh", "USA");
        dt.Rows.Add("Venkat Sai", "Dubai");
        dt.Rows.Add("Venkat Teja", "Pakistan");
        ds.Tables.Add(dt);
        ExportDataSetToExcel(ds);
    }
    public  void ExportDataSetToExcel(DataSet ds)
    {
        string AppLocation = "";
        AppLocation = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().CodeBase);
        AppLocation = AppLocation.Replace("file:\\", "");
        string date = DateTime.Now.ToShortDateString();
        date = date.Replace("/", "_");
        string filepath = AppLocation + "\\ExcelFiles\\" + "RECEIPTS_COMPARISON_" + date + ".xlsx";

        using (ClosedXML.Excel.XLWorkbook wb = new ClosedXML.Excel.XLWorkbook())
        {
            for (int i = 0; i < ds.Tables.Count; i++)
            {
                wb.Worksheets.Add(ds.Tables[i], ds.Tables[i].TableName);
            }
            wb.Style.Alignment.Horizontal = ClosedXML.Excel.XLAlignmentHorizontalValues.Center;
            wb.Style.Font.Bold = true;
            wb.SaveAs(filepath);
        }
    }
