            FileInfo newFile = new FileInfo(@"F:\mynewfile.xlsx");
            using (ExcelPackage xlPackage = new ExcelPackage(newFile))//如果mynewfile.xlsx存在，就打开它，否则就在该位置上创建
            {
                ExcelWorksheet worksheet = xlPackage.Workbook.Worksheets.Add("Tinned Goods");
                worksheet.Cells[1, 1].Value = "Product";
                worksheet.Cells[2, 1].Value = "Broad Beans";
                worksheet.Cells[3, 1].Value = "String Beans";
                worksheet.Cells[4, 1].Value = "Peas";
                worksheet.Cells[5, 1].Value = "Total";

                worksheet.Cells[1, 2].Value = "Tins Sold";//给单元格赋值             

                ExcelRange cell = worksheet.Cells[2, 2];
                cell.Value = 15;//另一种方式给单元格赋值

                string calcStartAddress = cell.Address;

                worksheet.Cells[3, 2].Value = 32;
                worksheet.Cells[4, 2].Value = 65;

                string calcEndAddress = worksheet.Cells[4, 2].Address;

                worksheet.Cells[5, 2].Formula = string.Format("SUM({0}:{1})", calcStartAddress, calcEndAddress);//使用公式计算值，并赋值给单元格


                worksheet.Column(1).Width = 15;//设置列宽

                xlPackage.Workbook.Properties.Title = "Sample 1";//设置excel的一些属性
                xlPackage.Workbook.Properties.Author = "John Tunnicliffe";
                xlPackage.Workbook.Properties.SetCustomPropertyValue("EmployeeID", "1147");

                xlPackage.Save();//保存Excel表格

简单使用（单元格赋值、使用公式等）

 

            using (ExcelPackage pck = new ExcelPackage())
            {
                //Create the worksheet
                ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Demo");

                //Load the datatable into the sheet, starting from cell A1. Print the column names on row 1
                ws.Cells["A1"].LoadFromDataTable(tbl, true);

                //Format the header for column 1-3
                using (ExcelRange rng = ws.Cells["A1:C1"])
                {
                    rng.Style.Font.Bold = true;
                    rng.Style.Fill.PatternType = ExcelFillStyle.Solid;                      //Set Pattern for the background to Solid
                    rng.Style.Fill.BackgroundColor.SetColor(Color.FromArgb(79, 129, 189));  //Set color to dark blue
                    rng.Style.Font.Color.SetColor(Color.White);
                }

                //Example how to Format Column 1 as numeric 
                using (ExcelRange col = ws.Cells[2, 1, 2 + tbl.Rows.Count, 1])
                {
                    col.Style.Numberformat.Format = "#,##0.00";
                    col.Style.HorizontalAlignment = ExcelHorizontalAlignment.Right;
                }

                //Write it back to the client
                Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
                Response.AddHeader("content-disposition", "attachment;  filename=ExcelDemo.xlsx");
                Response.BinaryWrite(pck.GetAsByteArray());
            }

在Web中使用

 

            FileInfo newFile = new FileInfo(@"F:\mynewfile.xlsx");
            using (ExcelPackage xlPackage = new ExcelPackage(newFile))
            {
                // get the first worksheet in the workbook
                ExcelWorksheet worksheet = xlPackage.Workbook.Worksheets[1];
                int iCol = 2;
                for (int iRow = 1; iRow < 6; iRow++)
                {
                    string valueStr = string.Format("Cell({0},{1}).Value={2}", iRow, iCol, worksheet.Cells[iRow, iCol].Value);//循环取出单元格值
                    string value_Str = string.Format("Cell({0},{1}).Formula={2}", 6, iCol, worksheet.Cells[6, iCol].Formula);//取公式（失败了）
                }
            }
