.Net下C#针对Excel开发控件汇总(ClosedXML,EPPlus,NPOI)
https://www.cnblogs.com/ryantocode/p/excelwriter.html
最近项目中需要一个导出Excel报告的功能，假期搜了一下，把其中比较主流的列一下，仅供参考。
功能需求：
- 创建并写入.xlsx Excel2007+版本的电子表格文件
- 不需要office组件支持，终端电脑无需安装ms office
- 简单的format，style,chart和formula支持（不用过于复杂），并且能够插入图片
- 速度，保证数据在万行以上表格写入速度
效果图：
一、ClosedXML
主页：https://github.com/ClosedXML/ClosedXML
需要引用OpenXMLSDK（DocumentFormat.OpenXml.dll），以简易面向对象的方式操作文件（类似Visual Basic for Applications (VBA)），文档和例子都比较完善
//创建workbook
using (var wb = new XLWorkbook(XLEventTracking.Disabled))
{
//设置默认Style
var style = wb.Style;
style.Font.FontName = "Microsoft YaHei";
style.Font.FontSize = 11;
//添加Sheets
var ws = wb.Worksheets.Add("Sheet001");
wb.Worksheets.Add("Sheet002");
//手动cell赋值
ws.Cell(1, 1).Value = "Project";
ws.Cell(1, 2).Value = "Project001";
ws.Cell("A2").Value = "User";
ws.Cell("B2").Value = "User001";
ws.Cell(3, 1).SetValue("Create Date");
ws.Cell(3, 2).SetValue(DateTime.Now);
//加重第一列文字
var rngHeader = ws.Range(1, 1, 3, 1);
rngHeader.Style
.Font.SetBold()
.Font.SetFontColor(XLColor.White)
.Fill.SetBackgroundColor(XLColor.SkyBlue)
.Alignment.SetHorizontal(XLAlignmentHorizontalValues.Center);
//合并cell
ws.Cell(5, 1).Value = "Data List";
var rngTitle = ws.Range(5, 1, 5, 5);
rngTitle.Merge();//ws1.Row(5).Merge();
rngTitle.Style
.Font.SetBold()
.Font.SetFontSize(15)
.Alignment.SetHorizontal(XLAlignmentHorizontalValues.Center);
//插入表格或数据,设置Timespan format
var fakeData = Enumerable.Range(1, 5)
.Select(x => new FakeData
{
Time = TimeSpan.FromSeconds(x * 123.667),
X = x,
Y = -x,
Address = "a" + x,
Distance = x * 100
}).ToArray();
var table = ws.Cell(6, 1).InsertTable(fakeData);
table.Style.Font.FontSize = 9;
var data = ws.Cell(13, 1).InsertData(fakeData);
data.Style.Font.FontSize = 9;
ws.Range(7, 1, 18, 1).Style.DateFormat.Format = "HH:mm:ss.000";
//插入图片
var image = ws.AddPicture("1.png");
image.MoveTo(ws.Cell(19, 1).Address);
image.Scale(0.3);
//调整列距
ws.Columns().AdjustToContents();//会花费写入数据一倍的时间
//保存文件
wb.SaveAs("ClosedXML.xlsx");
}

二、EPPlus
主页：https://github.com/JanKallman/EPPlus/
EPPlus不需要任何别的引用，文档和例子还算比较全
//创建workbook
using (var p = new ExcelPackage())
{
//添加Sheets
var ws= p.Workbook.Worksheets.Add("Sheet001");
p.Workbook.Worksheets.Add("Sheet002");
//手动cell赋值
ws.Cells[1,1].Value = "Project";
ws.Cells[1, 2].Value = "Project001";
ws.Cells["A2"].Value = "User";
ws.Cells["B2"].Value = "User001";
ws.Cells[3,1].Value = "Create Date";
ws.Cells[3,2].Value = DateTime.Now;
ws.Cells[3, 2].Style.Numberformat.Format = "YYYY/MM/DD";
//加重第一列文字
var rngHeader = ws.Cells[1, 1, 3, 1];
rngHeader.Style.Font.Bold = true;
rngHeader.Style.Font.Color.SetColor(System.Drawing.Color.White);
rngHeader.Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
rngHeader.Style.Fill.BackgroundColor.SetColor(System.Drawing.Color.DodgerBlue);
rngHeader.Style.HorizontalAlignment = OfficeOpenXml.Style.ExcelHorizontalAlignment.Center;
//合并cell
ws.Cells[5, 1].Value = "Data List";
var rngTitle = ws.Cells[5, 1, 5, 5];
rngTitle.Merge = true;
rngTitle.Style.Font.Size = 15;
rngTitle.Style.Font.Bold = true;
rngTitle.Style.HorizontalAlignment = OfficeOpenXml.Style.ExcelHorizontalAlignment.Center;
//插入表格或数据,设置Timespan format
var fakeData = Enumerable.Range(1, 5)
.Select(x => new FakeData
{
Time = TimeSpan.FromSeconds(x * 123.667),
X = x,
Y = -x,
Address = "a" + x,
Distance = x * 100
}).ToArray();
ws.Cells[6, 1].LoadFromCollection(fakeData, true, OfficeOpenXml.Table.TableStyles.Medium27);
ws.Cells[13, 1].LoadFromArrays(
fakeData.Select(x => new object[] {x.Time, x.X, x.Y, x.Address, x.Distance}));
ws.Cells[6, 1, 18, 1].Style.Numberformat.Format = "HH:mm:ss.000";
//插入图片
var image = ws.Drawings.AddPicture("picture", new FileInfo("1.png"));
image.From.Row = 19;
image.From.Column = 0;
image.SetSize(30);
//设置默认Style
ws.Cells[ws.Dimension.Address].Style.Font.Name = "Microsoft YaHei";
//调整列距
ws.Cells.AutoFitColumns(0);//会花费写入数据一倍的时间
//保存文件
p.SaveAs(new FileInfo("EPPlus.xlsx"));
}
三、NPOI
官网：https://github.com/tonyqus/npoi .netcore version:https://github.com/dotnetcore/NPOI
需要引用SharpZipLib，可以读写Word和Excel，例子比较全，系统点的文档没有找到，不过是国人的开源项目，百度应该能找到很多
参考：

http://www.cnblogs.com/yinrq/p/5590970.html
http://www.cnblogs.com/hanzhaoxin/p/4232572.html 基于NPIO的Report控件
using (var fs = new FileStream("NPOI.xlsx", FileMode.Create, FileAccess.Write))
{
//创建workbook
IWorkbook wb = new XSSFWorkbook();
//添加Sheets
var ws = wb.CreateSheet("Sheet001");
wb.CreateSheet("Sheet002");
//手动cell赋值
ws.CreateRow(0).CreateCell(0).SetCellValue("Project");
ws.CreateRow(0).CreateCell(1).SetCellValue("Project001");
ws.CreateRow(1).CreateCell(0).SetCellValue("User");
ws.CreateRow(1).CreateCell(1).SetCellValue("User001");
ws.CreateRow(2).CreateCell(0).SetCellValue("Create Date");
ws.CreateRow(2).CreateCell(1).SetCellValue(DateTime.Now);
wb.Write(fs);
}
四、Benchmarks
以上三个控件的简单测试，10000条数据写入
using (var wb = new XLWorkbook(XLEventTracking.Disabled))
{
var ws = wb.AddWorksheet("1");
ws.Column(1).Style.DateFormat.Format = "HH:mm:ss.000";
int rowCount = 1;
foreach (var fakeData in data)
{
rowCount++;
ws.Cell(rowCount, 1).Value = fakeData.Time;
ws.Cell(rowCount, 2).Value = fakeData.X;
ws.Cell(rowCount, 3).Value = fakeData.Distance;
ws.Cell(rowCount, 4).Value = fakeData.Address;
}
wb.SaveAs("ClosedXML.xlsx");
}
using (var wb = new ExcelPackage())
{
var ws = wb.Workbook.Worksheets.Add("1");
ws.Column(1).Style.Numberformat.Format = "HH:mm:ss.000";
ws.Cells[1, 1].LoadFromCollection(data,true,
OfficeOpenXml.Table.TableStyles.Medium2,
System.Reflection.BindingFlags.Public|System.Reflection.BindingFlags.Instance,
new System.Reflection.MemberInfo[]
{
typeof(FakeData).GetProperty("Time"),
typeof(FakeData).GetProperty("X"),
typeof(FakeData).GetProperty("Distance"),
typeof(FakeData).GetProperty("Address")
});
wb.SaveAs(new FileInfo("EPPlus.xlsx"));
}
using (var fs = new FileStream("NPOI.xlsx", FileMode.Create, FileAccess.Write))
{
var wb = new XSSFWorkbook();
var ws = wb.CreateSheet("1");
int rowCount = 0;
IRow row;
foreach (var fakeData in data)
{
row = ws.CreateRow(rowCount++);
row.CreateCell(0).SetCellValue(fakeData.Time.ToString(@"hh\:mm\:ss\.fff"));
row.CreateCell(1).SetCellValue(fakeData.X);
row.CreateCell(2).SetCellValue(fakeData.Distance);
row.CreateCell(3).SetCellValue(fakeData.Address);
}
wb.Write(fs);
}

总体上EPPlus在速度和内存上都最佳，感觉ClosedXML在API调用上方便一些，文档写全面一些。
五、其他
SpreadSheetLight 之前项目使用的，读写都可以，需要OpenXMLSDK 2.5
ExcelDataReader Excel 03-07 文件读取，只需要快速读取excel文件的可以用这个
