fastNpoi

介绍

对npoi.core进行二次封装,目的是调用更加方便

安装教程

1.nuget 控制台输入

Install-Package fastNpoi -Version 1.0.1

2.nuget 管理程序 搜索fastNpoi 输入图片说明

使用说明
  1. 依赖注入
serices.AddScoped(typeof(IFastNpoi<>), typeof(FastNpoi<>));
  1. 非依赖注入
new FastNpoi<T>()
  1. 实体特性声明
public class TestModel
    {
        [Npoi(headerName:"主键",mergeCell:false,position:2)]
        public int Id { get; set; }
        [Npoi(headerName: "名称",position:1)]
        public string? Name { get; set; }
        [Npoi(headerName: "随机数")]
        public int RandomNum { get; set; }
        [Npoi(headerName: "创建日期")]
        public DateTime CreateTime { get; set; } = DateTime.Now;
    }

headerName:对应的表头名称,mergeCell:本条数据和下一条数据的值相同，合并单元格，默认false，position:表头位置，默认999，数值越大越靠后，OperationType：表头类型分为导入、导出以及导入导出,width:单元格长度

  1. 代码声明表头和实体的对应关系
var easyNpoi = serviceProvider.GetService<IFastNpoi<TestModel>>();
easyNpoi.InitWorkbook(@"C:\Users\53205\Desktop\test\20220708124735.xlsx").GetSheet()
.HeaderMapper("id",t=>t.Id)//通过表达式声明属性
.HeaderMapper("id","Id");//通过属性的字符串声明

用代码声明的表头映射优先级大于特性标注

  1. 简单的导入
var easyNpoi = serviceProvider.GetService<IFastNpoi<TestModel>>();
var list1 = easyNpoi.InitWorkbook(@"C:\Users\53205\Desktop\test\20220708124735.xlsx").GetSheet().ToList();
  1. 简单的导出
var list=new List<TestModel>(1000);
for(int i=0;i<1000; i++)
{
    TestModel item = new TestModel()
    {
        Id = i,
        Name = $"创建用的名称{i}",
        RandomNum = new Random().Next()
    };
    list.Add(item);
}
var easyNpoi = serviceProvider.GetService<IFastNpoi<TestModel>>();
easyNpoi.CreateWorkbook().CreateSheet()
    .SetDataList(list)
    .ToFile(@"C:\Users\53205\Desktop\test");

7.设置表头样式

easyNpoi.CreateWorkbook().CreateSheet().SetHeaderStyle(workbook =>
{
    var style= workbook.CreateCellStyle();
    var font = workbook.CreateFont();
    font.FontName = "宋体";
    font.FontHeight = 15;
    font.FontHeightInPoints = 12;
    font.Color = NPOI.HSSF.Util.HSSFColor.Blue.Index;
    style.FillForegroundColor = NPOI.HSSF.Util.HSSFColor.Red.Index;
    style.FillPattern = FillPattern.SolidForeground;
    style.SetFont(font);
    return style;
});
  1. 设置数据样式
easyNpoi.CreateWorkbook().CreateSheet().SetDataStyle(workbook =>
{
    var style= workbook.CreateCellStyle();
    var font = workbook.CreateFont();
    font.FontName = "宋体";
    font.FontHeight = 15;
    font.FontHeightInPoints = 12;
    font.Color = NPOI.HSSF.Util.HSSFColor.Blue.Index;
    style.FillForegroundColor = NPOI.HSSF.Util.HSSFColor.Red.Index;
    style.FillPattern = FillPattern.SolidForeground;
    style.SetFont(font);
    return style;
});

9.不生成表头，用于读取模板内表头使用并根据模板表头进行赋值

easyNpoi.CreateWorkbook().CreateSheet().DisableHeader();//不生成表头 内部逻辑是先将表头写入 然后读取表头的信息按映射名赋值

10.数据修改 一般用于实体内存在字典映射项

easyNpoi.CreateWorkbook().CreateSheet().DataMapper(t=>t.Id=0)//相当于foreach

11.各种漂移量设置

easyNpoi.CreateWorkbook().CreateSheet()
.SetHeaderIndex(0)//表头所在行的索引 默认为0
.SetColumnStartIndex(0)//第一列所在的索引 默认为0
.SetHeaderSkipNumber(1)//表头和数据列之间的间隔 默认为1
.SetRowSkipNumber(1)//每一行之间的间隔 默认为1
.SetColumnSkipNumber(1)//每一列之间建的间隔 默认为1

12.手动合并单元格(原生api,做了简单封装)

easyNpoi.CreateWorkbook().CreateSheet().MergeCell(int startRowIndex,int endRowIndex,int startColumnIndex,int endColumnIndex);

13.生成标题列

easyNpoi.CreateWorkbook().CreateSheet()
    .SetHeaderIndex(1)//表头向下偏移1行
    .SetDataList(list)
    .SheetMapper(sheet =>
        {
            //对sheet进行追加操作,在第一行第一列加入标题数据，如果还需要别的样式,在这个action里面调用原生Api操作即可
            var row = sheet.CreateRow(0);
            var cell = row.CreateCell(0);
            cell.SetCellValue("测试的标题");
        })
    .MergeCell(0, 0, 0, 4)//第一行的4个列合并成一个单元格
    .ToFile(@"C:\Users\53205\Desktop\test");

14.对单元格添加批注

easyNpoi.CreateWorkbook().CreateSheet().
    .SetCommentVisable(true)//生成的批注默认显示
    .CommentCell(new List<CommentModel>()
    {
        // 声明批注的具体位置
        new CommentModel(){RowIndex=4,ColumnIndex=0,Message="测试一个批注"},
        new CommentModel(){RowIndex=4,ColumnIndex=0,Message="测试一个批注2"},
    })
    .ToFile(@"C:\Users\53205\Desktop\test");

15.取值和赋值实现类替换（默认实现使用反射实现,可自行替换成emit或者表达式树取值赋值提高速度） 首先实现接口

public interface IDataOperation
    {
        object GetValue<T>(T data, PropertyInfo property) where T : class, new();
        void SetValue<T>(T data, PropertyInfo property, object value) where T : class, new();
    }

然后调用

easyNpoi.CreateWorkbook().CreateSheet().
    SetDataOperation(你的实现类)；

16.接口列表
