优秀开源项目:MyXls

2013年12月10日 ⁄ 综合 ⁄ 共 10438字 ⁄ 字号 评论关闭

MyXls是用C#开源项目,可以应用于silverlight 、asp.net 或者  .net应用程序上。它根据微软公开的Excle文档格式文件(BIFF),以二进制格式直接生成excel文档,支持Excel versions  97 - 2007.  。这意味着可以不用在服务器上安装office就能够以excle格式输出数据库中存储的数据了。这对于许多项目来说都是很有用的。

     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。
     目前MyXls还不支持在excel文档中生成对象(如、文本框、按钮等)。MyXls主页称即将实现对excel文件的读取功能,个人认为读取的功能的用处还不是很多。

以下转自http://www.cnblogs.com/heone/archive/2009/03/08/1283211.html

下载的源码中包含了几个简单的示例,不过实在是太简单了。让我不得不仔细分析代码,才知道怎么使用。
示例来了:下载MyXls示例文件

string sheetName = "chc 实例";
         Worksheet sheet = xls.Workbook.Worksheets.AddNamed(sheetName);//填加名为"chc 实例"的sheet页
         Cells cells = sheet.Cells;//Cells实例是sheet页中单元格(cell)集合
         //单元格1-base
         Cell cell = cells.Add(1, 2, "抗");//设定第一行,第二例单元格的值
         cell.HorizontalAlignment = HorizontalAlignments.Centered;//设定文字居中
         cell.Font.FontName = "方正舒体";//设定字体
         cell.Font.Height = 20 * 20;//设定字大小(字体大小是以 1/20 point 为单位的)
         cell.UseBorder = true;//使用边框
         cell.BottomLineStyle = 2;//设定边框底线为粗线
         cell.BottomLineColor = Colors.DarkRed;//设定颜色为暗红

        //cell的格式还可以定义在一个xf对象中
         XF cellXF = xls.NewXF();//为xls生成一个XF实例(XF是cell格式对象)
         cellXF.HorizontalAlignment = HorizontalAlignments.Centered;//设定文字居中
         cellXF.Font.FontName = "方正舒体";//设定字体
         cellXF.Font.Height = 20 * 20;//设定字大小(字体大小是以 1/20 point 为单位的)
         cellXF.UseBorder = true;//使用边框
         cellXF.BottomLineStyle = 2;//设定边框底线为粗线
         cellXF.BottomLineColor = Colors.DarkRed;//设定颜色为暗红
        
         cell = cells.AddValueCellXF(2, 2,"震", cellXF);//以设定好的格式填加cell

        cellXF.Font.FontName = "仿宋_GB2312";
         cell = cells.AddValueCellXF(3, 2, "救", cellXF);//格式可以多次使用

        ColumnInfo colInfo = new ColumnInfo(xls, sheet);//生成列格式对象
         //设定colInfo格式的起作用的列为第2列到第5列(列格式为0-base)
         colInfo.ColumnIndexStart = 1;//起始列为第二列
         colInfo.ColumnIndexEnd = 5;//终止列为第六列
         colInfo.Width = 15 * 256;//列的宽度计量单位为 1/256 字符宽
         sheet.AddColumnInfo(colInfo);//把格式附加到sheet页上(注:AddColumnInfo方法有点小问题,不给把colInfo对象多次附给sheet页)
         colInfo.ColumnIndexEnd = 6;//可以更改列对象的值
         ColumnInfo colInfo2 = new ColumnInfo(xls, sheet);//通过新生成一个列格式对象,才到能设定其它列宽度
         colInfo2.ColumnIndexStart = 7;
         colInfo2.ColumnIndexEnd = 8;
         colInfo2.Width = 1 * 256;
         sheet.AddColumnInfo(colInfo2);

         MergeArea meaA = new MergeArea(1,2,3,4);//一个合并单元格实例(合并第一行、第三例 到 第二行、第四例)
         sheet.AddMergeArea(meaA);//填加合并单元格
         cellXF.VerticalAlignment=  VerticalAlignments.Centered;
         cellXF.Font.Height = 48 * 20;
         cellXF.Font.Bold = true;
         cellXF.Pattern = 3;//设定单元格填充风格。如果设定为0,则是纯色填充
         cellXF.PatternBackgroundColor = Colors.DarkRed;//填充的底色
         cellXF.PatternColor = Colors.DarkGreen;//设定填充线条的颜色
         cell = cells.Add(1, 3, "灾",cellXF);

如果从快速生成Excel报表,不调用Excel组件角度讲,MyXls可能是一种最好的选择之一,当然使用Open Xml方式也是不错的选择。MyXls是一个用C#语言开发的生成Excel报表的优秀开源项目,在快速开发中我一直比较喜欢它。MyXls官方的解释:
Writes and now Reads Excel files quickly and easily, including  formatting. Generate Excel files for ASP.NET sites or .NET applications.  Doesn't require Excel on the server or any licensing $. Compatible with  Excel versions >= 97
MyXls可以用在.NET平台的诸如Windows Form,Asp.NET项目中,当然Sharepoint项目中也可以使用,支持的Excel版本包裹2003,2007等等(Excel versions >= 97)。
大凡开源项目的作者,多半都是重口味者,MyXls开源组件基于的技术是Excel文件的二进制格式(BIFF),  
OpenOffice.org
发布过的俩个文档Excel File Format (BIFF8)SpecificationMicrosoft
Compound
Document (OLE2) Format SpecificationExcel的二进制格式做了一个比较详细的说明,MyXls的作者正是凭借这些信息把它开发而成的。

下面通过2个例子来使用这个开源组件
生成单个Worksheet:

                        XlsDocument doc = new XlsDocument();

                        doc.FileName = "MyXlsWebAppDemo.xls";

                        Worksheet sheet = doc.Workbook.Worksheets.Add("Hello World Sheet");

                        Cell cell = sheet.Cells.Add(1, 1, "Hello,MyXls!");

                        for (int i = 2; i <= 10; i++)

                        {

                                cell = sheet.Cells.Add(i, 1, "51CTO五岁了!");

                                cell.Font.Weight = FontWeight.Bold;

                                cell.Font.ColorIndex =2;//白 红 绿 蓝 黄 粉红等等颜色,可以通过源代码了解颜色

                        }

                        

                        doc.Send();
生成的报表如下:
生成多个WorkSheet
XlsDocument xls = new XlsDocument();//新建一个xls文档

                        xls.FileName = "MyXlsDemo.xls";//设定Excel文件名


                        xls.SummaryInformation.Author = "Terry Li"; //填加Excel文件作者信息

                        xls.SummaryInformation.Subject = "MyXls Demo";//填加文件主题信息

                        xls.DocumentSummaryInformation.Company = "in2bits.org";//填加文件公司信息


string sheetName = "第一个Sheet Demo";#region   


                        string sheetName = "第一个Sheet Demo";

                        Worksheet sheet = xls.Workbook.Worksheets.Add(sheetName);//填加名为"第一个Sheet Demo"的sheet页

                        Cells cells = sheet.Cells;//Cells实例是sheet页中单元格(cell)集合

                        //单元格1-base

                        Cell cell = cells.Add(2, 3, "三");//设定第2行,第3例单元格的值

                        cell.HorizontalAlignment = HorizontalAlignments.Centered;//设定文字居中

                        cell.Font.FontName = "行楷";//设定字体

                        cell.Font.Height = 30 * 20;//设定字大小(字体大小是以 1/20 point 为单位的)
