用MyXls生成Excel报表（C#）总结

总结了一下MyXls导出Excle，分页之后导出全部数据。当然还有一些简单的方法。但是功能就局限了。

一：（网上搜集）

MyXLS 是一个快速和简单的读写 Excel 文件的 .NET 组件，可用在 ASP.NET 网站和 .NET 应用程序中，无需安装 Excel 程序，支持 Excel 97 以及以后的版本。

       目前MyXls已经实现了单元格（cell）的格式设置，包括文本颜色、文本大小、字体、单位格边框、底色、列宽、行高，合并单元格，多个sheet页等功能。以下是MyXLS组件的一些用法：

1.创建一个Excel文档：

XlsDocument xls =new XlsDocument();

2.创建一个WorkSheet：

Worksheet ws = xls.Workbook.Worksheets.Add("WorkSheet1");

3.指定列格式：

ColumnInfo colInfo =new ColumnInfo(xls, ws);

colInfo.ColumnIndexStart =;

colInfo.ColumnIndexEnd =17;

colInfo.Width =15*256;

ws.AddColumnInfo(colInfo);

列格式必须每次都要重新定义，一个列格式不能重复使用。

4.指定单元格样式：

XF xf = xls.NewXF();

xf.HorizontalAlignment = HorizontalAlignments.Centered;

xf.VerticalAlignment = VerticalAlignments.Centered;

xf.Pattern =1;

xf.PatternColor = Colors.Default30;

xf.UseBorder =true;

xf.TopLineStyle =1;

xf.TopLineColor = Colors.Black;

xf.BottomLineStyle =1;

xf.BottomLineColor = Colors.Black; xf.LeftLineStyle =1;

xf.LeftLineColor = Colors.Black;

xf.RightLineStyle =1;

xf.RightLineColor = Colors.Black;

xf.Font.Bold =true;

xf.Font.Height =11*20;

xf.Font.ColorIndex =1;

5.给单元格赋值：

ws.Cells.Add(2, 3, "金额(万元)", xf);

6.合并单元格：

ws.Cells.Merge(1, 2, 2, 2); //或者ws.AddMergeArea(new MergeArea(1, 2, 1, 1));

7.MyXls合并单元格有个bug，就是合并后只是第一个单元格有样式，其余的样式丢失。所以写了个函数来合并：

MergeRegion(ref ws, xf, "机构", 1, 1, 2, 1);

publicvoid MergeRegion(ref Worksheet ws, XF xf, string title, int startRow, int startCol, int endRow, int endCol)

{     

  for (int i = startCol; i <= endCol; i++)  

      {    

         for (int j = startRow; j <= endRow; j++)  

            {            

     　　　　 ws.Cells.Add(j, i, title, xf);  

            }    

    }      

  ws.Cells.Merge(startRow, endRow, startCol, endCol); }

虽然效率不怎么样，但是对于出Excel报表，还OK。

8.指定单元格格式：

cell.Format = StandardFormats.Decimal_1;

具体更多请参考源代码的StandardFormats类。

9.保存或者发送Excel：

xls.Send(); //或者xls.Save();

二、结合项目

实例：

View Code

  1         protected void btnExcel_Click(object sender, EventArgs e)

  2         {

  3             DataTable dt = (DataTable)ViewState["dt"];

  4             string item = "客户：" + name + " 从" + start + "至" + end + " 采购详单";

  5             ExcelExport(dt, item);

  6         }

  7         //先添加引用给出的DLL文件

  8         private void ExcelExport(DataTable dt, string item)

  9         {

 10 

 11             XlsDocument xls = new XlsDocument();

 12             xls.FileName = "采购详单.xls";//指定文件名

 13 

 14             Worksheet sheet = xls.Workbook.Worksheets.Add("Inventory");

 15 

 16             #region 设置各数据列的大小

 17             ColumnInfo colInfo = null;

 18             int a = 0;

 19             int b = 0;

 20             //15列

 21             for (int i = 0; i < 15; i++)

 22             {

 23                 a = i == 0 ? 0 : (i + 1);

 24                 b = i == 0 ? 1 : (i + 1);

 25                 colInfo = new ColumnInfo(xls, sheet);

 26                 colInfo.ColumnIndexStart = (ushort)a;

 27                 colInfo.ColumnIndexEnd = (ushort)b;

 28                 colInfo.Width = 13 * 256;

 29                 sheet.AddColumnInfo(colInfo);

 30             }

 31             #endregion

 37             MergeArea maTitle = new MergeArea(1, 2, 1, 15);

 38             sheet.AddMergeArea(maTitle);

 39             XF xfTitle = xls.NewXF();

 40             xfTitle.HorizontalAlignment = HorizontalAlignments.Centered;
