几年前就使用过EPPlus来读写Excel,后来没有这方面的需求,没有再更新该组件来测试,最近整理测试代码,顺便更新了最新的组件,不得不佩服EPPlus开发团队,功能更加强大了。
官网:https://www.epplussoftware.com/zh/
Github: https://github.com/EPPlusSoftware/EPPlus
网上又很多帮助文档,可供参考。我仅仅是测试验证EEPLUS5的功能。
创建项目,NuGet安装EPPlus5
当前版本5.8.3
完成后添加了依赖的组件如下:
用于非商业测试,所以需要声明为非商业应用:
在代码中声明
ExcelPackage.LicenseContext = LicenseContext.NonCommercial;
或在Config中声明
测试创建Excel数据表
创建一个简单的Excel,创建表,创建一些测试数据。
public static void Created()
{
FileInfo fi = new FileInfo("MySample.xlsx");
using (var package = new ExcelPackage(fi))
{
var worksheet = package.Workbook.Worksheets.Add("Test");
//Add the headers
worksheet.Cells[1, 1].Value = "ID";
worksheet.Cells[1, 2].Value = "TestPointName";
worksheet.Cells[1, 3].Value = "TestValue";
//add Value
worksheet.Cells["A2"].Value = 12001;
worksheet.Cells["B2"].Value = "VoltageTest";
worksheet.Cells["C2"].Value = 3.4;
worksheet.Cells["A3"].Value = 12002;
worksheet.Cells["B3"].Value = "CurrentTest";
worksheet.Cells["C3"].Value = 52;
worksheet.Cells["A4"].Value = 12003;
worksheet.Cells["B4"].Value = "Temperature";
worksheet.Cells["C4"].Value = 19.02;
worksheet.Cells.AutoFitColumns(0); //Autofit columns for all cells
package.Save();
}
在查询执行目录下创建了Excel文件:MySample.xlsx
内容如下:
Github完整代码如下:
using (var package = new ExcelPackage())
{
//Add a new worksheet to the empty workbook
var worksheet = package.Workbook.Worksheets.Add("Inventory");
//Add the headers
worksheet.Cells[1, 1].Value = "ID";
worksheet.Cells[1, 2].Value = "Product";
worksheet.Cells[1, 3].Value = "Quantity";
worksheet.Cells[1, 4].Value = "Price";
worksheet.Cells[1, 5].Value = "Value";
//Add some items...
worksheet.Cells["A2"].Value = 12001;
worksheet.Cells["B2"].Value = "Nails";
worksheet.Cells["C2"].Value = 37;
worksheet.Cells["D2"].Value = 3.99;
worksheet.Cells["A3"].Value = 12002;
worksheet.Cells["B3"].Value = "Hammer";
worksheet.Cells["C3"].Value = 5;
worksheet.Cells["D3"].Value = 12.10;
worksheet.Cells["A4"].Value = 12003;
worksheet.Cells["B4"].Value = "Saw";
worksheet.Cells["C4"].Value = 12;
worksheet.Cells["D4"].Value = 15.37;
//Add a formula for the value-column
worksheet.Cells["E2:E4"].Formula = "C2*D2";
//Ok now format the values
using (var range = worksheet.Cells[1, 1, 1, 5])
{
range.Style.Font.Bold = true;
range.Style.Fill.PatternType = ExcelFillStyle.Solid;
range.Style.Fill.BackgroundColor.SetColor(Color.DarkBlue);
range.Style.Font.Color.SetColor(Color.White);
}
worksheet.Cells["A5:E5"].Style.Border.Top.Style = ExcelBorderStyle.Thin;
worksheet.Cells["A5:E5"].Style.Font.Bold = true;
worksheet.Cells[5, 3, 5, 5].Formula = string.Format("SUBTOTAL(9,{0})", new ExcelAddress(2, 3, 4, 3).Address);
worksheet.Cells["C2:C5"].Style.Numberformat.Format = "#,##0";
worksheet.Cells["D2:E5"].Style.Numberformat.Format = "#,##0.00";
//Create an autofilter for the range
worksheet.Cells["A1:E4"].AutoFilter = true;
worksheet.Cells["A2:A4"].Style.Numberformat.Format = "@"; //Format as text
//There is actually no need to calculate, Excel will do it for you, but in some cases it might be useful.
//For example if you link to this workbook from another workbook or you will open the workbook in a program that hasn't a calculation engine or
//you want to use the result of a formula in your program.
worksheet.Calculate();
worksheet.Cells.AutoFitColumns(0); //Autofit columns for all cells
// Lets set the header text
worksheet.HeaderFooter.OddHeader.CenteredText = "&24&U&\"Arial,Regular Bold\" Inventory";
// Add the page number to the footer plus the total number of pages
worksheet.HeaderFooter.OddFooter.RightAlignedText =
string.Format("Page {0} of {1}", ExcelHeaderFooter.PageNumber, ExcelHeaderFooter.NumberOfPages);
// Add the sheet name to the footer
worksheet.HeaderFooter.OddFooter.CenteredText = ExcelHeaderFooter.SheetName;
// Add the file path to the footer
worksheet.HeaderFooter.OddFooter.LeftAlignedText = ExcelHeaderFooter.FilePath + ExcelHeaderFooter.FileName;
worksheet.PrinterSettings.RepeatRows = worksheet.Cells["1:2"];
worksheet.PrinterSettings.RepeatColumns = worksheet.Cells["A:G"];
// Change the sheet view to show it in page layout mode
worksheet.View.PageLayoutView = true;
// Set some document properties
package.Workbook.Properties.Title = "Invertory Test";
package.Workbook.Properties.Author = "Ritchie ";
package.Workbook.Properties.Comments = "This sample demonstrates how to create an Excel workbook using EPPlus";
// Set some extended property values
package.Workbook.Properties.Company = "EPPlus Software AB TEST";
// Set some custom property values
package.Workbook.Properties.SetCustomPropertyValue("Checked by", "Ritchie");
package.Workbook.Properties.SetCustomPropertyValue("AssemblyName", "EPPlus");
var xlFile = FileUtil.GetCleanFileInfo("01-GettingStarted.xlsx");
// Save our new workbook in the output directory and we are done!
package.SaveAs(xlFile);
return xlFile.FullName;
}
创建的表格如下:
内容如下:
效果杠杠的!
