fastNpoi
介绍
对npoi.core进行二次封装,目的是调用更加方便 (此文档是2.0版本的 1.x版本请看之前的老文档) 代码地址 https://gitee.com/tengfei8771/fast-npoi 2.0分支
安装教程
1.nuget 控制台输入
Install-Package fastNpoi -Version 2.0.0
2.nuget 管理程序 搜索fastNpoi
使用说明
- 依赖注入
serices.AddScoped(typeof(IFastNpoi), typeof(FastNpoi));
- 非依赖注入
new FastNpoi()
- 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;
[Npoi(headerName: "图片",dataType:DataType.Image,columnWidth:30*256)]
public string Image { get; set; }
[Npoi(headerName:"公式列",dataType:DataType.Formula)]
public string forumal { get; set; }
}
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 dataType:数据类型,分为text(文本类型),Number(数值类型),Formula(公式类型),Image(图片类型) ps:图片类型数据无论导入和导出,都需要定义为string类型,获取的数据为base64字符串。
- 动态表头和实体的对应关系
var easyNpoi = serviceProvider.GetService<IFastNpoi>();
easyNpoi.InitWorkbook(@"C:\Users\53205\Desktop\test\20220708124735.xlsx").GetSheet<TestModel>()
.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
.SetIgnoreProperty(t=>t.Name);//声明忽略Name属性列(如果name属性有标记特性依旧忽略)
用代码声明的表头映射优先级大于特性标注
- 简单的导入
var easyNpoi = serviceProvider.GetService<IFastNpoi<TestModel>>();
var list1 = easyNpoi.InitWorkbook(@"C:\Users\53205\Desktop\test\20220708124735.xlsx").GetSheet().ToList();
- 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>();
easyNpoi.CreateWorkbook().CreateSheet<TestModel>()
.SetDataList(list)
.ToFile(@"C:\Users\53205\Desktop\test");
7.设置表头样式
easyNpoi.CreateWorkbook().CreateSheet<TestModel>().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;
});
- 设置数据样式
easyNpoi.CreateWorkbook().CreateSheet<TestModel>().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.多数据源,导入同一个workbook
easyNpoi.CreateWorkbook()
.CreateSheet<TestModel>()
.SetDataList(list1)
.WriteToSheet()
.CreateSheet<TestModel1>()
.SetDataList(list2)
.WriteToSheet()
.ToByte();//list1和list2的元素为TestModel和TestModel1,执行之后将会把数据写入不同的shet中
10.数据修改 一般用于实体内存在字典映射项
easyNpoi.CreateWorkbook().CreateSheet<TestModel>().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<TestModel>().MergeCell(int startRowIndex,int endRowIndex,int startColumnIndex,int endColumnIndex);
13.生成标题列
easyNpoi.CreateWorkbook().CreateSheet<TestModel>()
.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
.WriteToSheet()
.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"},
})
.WriteToSheet()
.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<TestModel>().
SetDataOperation(你的实现类);
16.动态解析json对象,并将其解析成为列 首先实现接口
easyNpoi.CreateWorkbook().CreateSheet<TestModel>()
.SetJsonMapping(t=>t.JsonStr,new Dictionary<string, string>()
{
{"json的姓名","name" },//key为列名,value为json数据内的key
{"json的value","value" }
})
17.使用excel模板导出数据
应用 Excel模板为:
| A | B | | ------ | --| |{{test.Id| test.Name}} | |{template.Prop} | 表格内容 | 对象集合的声明为{{}}双括号,包裹全部需输出的属性({{和}}分别写在属性开始单元格和结束单元格内) 单个对象的声明为{}单括号(每个属性都需要包在{}内)
easyNpoi.InitWorkbook(@"C:\Users\tengfei8771\Desktop\excel\20220922105953.xlsx")
.UseTemplateSheet()
.SetData("ParamName",list[0])
.SetDataList("listParamName", list)
.WriteToSheet()
.ToFile(@"C:\Users\tengfei8771\Desktop\excel");
SetData(string paramName,T data) where T:class
//单个实体数据声明,对应Excel模板字符串为{paramName.PropertyName}
SetDataList(string paramName,IEnumerable<T> dataList)
//集合数据声明,对应Excel模板字符串为{{paramName.PropertyName}}
