如何使用c#将JQgrid数据导出到Excel?

我已经做了一些关于这方面的研究,但大多数的解决scheme是为MVC ..我只是使用Asp.net 3.5我怎么能实现这个button点击..我应该包括任何图书馆或其他..请帮助..

我在答案中发布的代码几乎可以在任何用C#编写的ASP.NET代码中进行修改。 助手类DataForExcel (请参阅文件DataForExcel.cs )具有构造函数

 public DataForExcel(string[] headers, List<string[]> data, string sheetName) 

或多一点“高级”版本

 public DataForExcel(string[] headers, DataType[] colunmTypes, List<string[]> data, string sheetName) 

它允许指定哪些列具有数字数据types。 参数List<string[]> data是需要导出到Excel的数据。 参数string[] headers指定输出的第一行的数据。

DataForExcel类只有一个公共方法

 public void CreateXlsxAndFillData(Stream stream) 

用填充的.XLSX Excel文件的二进制表示填充stream

为了从你的ASP.NET方法返回二进制数据(例如ASHX处理程序),你只需要做几乎相同的事情从我的答案ExecuteResult

  • using (var stream = new MemoryStream()) {...}创build内存stream
  • 创build需要导出到Excel的DataForExcel对象var dataExcel = new DataForExcel (new []{"Id", "Votes", "Title"}, "Questions.xlsx", "Name or Sheet");
  • response.AddHeader ("content-disposition", "attachment; filename=Questions.xlsx");
  • response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
  • response.ContentEncoding = Encoding.UTF8;
  • stream.WriteTo (response.OutputStream);
  • response.Flush();

就是这样

更新 :我修改了我之前发布的代码,以非常简单的方式从网格中创buildExcel文件(以.xlsx格式)。 如果您使用OpenXML SDK 2.0,那么您可以使用.NET 3.5。 OpenXML SDK 2.5需要.NET 4.0或更高版本。

build议的代码允许将数据的string[][]转换为二进制Excel数据,并将结果写入stream中。 您可以像我之前描述的那样使用MemoryStream从任何ASP.NET应用程序返回Excel。

build议的代码包含一个带有一个公共静态方法FillSpreadsheetDocument ExportToExcel静态类,它可以通过以下方式使用

 var data = new[] { new [] {"Tom", "30", "x", "", "1974-06-16"}, new [] {"Margarita", "34", "x", "x", "1978-10-02"}, new [] {"Bob", "7", "", "", "2005-06-26"}, new [] {"Oleg", "48", "x", "x", "1964-09-11"}, new [] {"Frank", "29", "", "x", "1983-01-28"} }; using (var stream = new FileStream("Test.xlsx", FileMode.Create)) { ExportToExcel.FillSpreadsheetDocument(stream, new[] { new ColumnModel { Type = DataType.String, Alignment = HorizontalAlignment.Left, Header = "Name" }, new ColumnModel { Type = DataType.Integer, Header = "Age" }, new ColumnModel { Type = DataType.String, Header = "Is Married", Alignment = HorizontalAlignment.Center, IsRotatedHeader = true }, new ColumnModel { Type = DataType.String, Header = "Has Children", Alignment = HorizontalAlignment.Center, IsRotatedHeader = true }, new ColumnModel { Type = DataType.Date, Header = "Birthday", Alignment = HorizontalAlignment.Left } }, data, "Friends"); } 

它会生成一个"Test.xlsx"并显示一张“朋友”

在这里输入图像描述

列的宽度将不会被设置,但是在两次点击(全部select并在列之间双击),用户可以像上面的构build那样将列的宽度设置为最佳宽度。 所有的单元格都有格式化的数据(没有“通用”格式)。 我使用整数,date和纯string。 人们可以很容易地创build中心alignment或右alignment文本的列。

您可以轻松修改代码,以便使用更多不同的文本格式。 这只是一个例子,如何使用格式化的单元格生成真正的Excel文档。

工作Visual Studio 2008项目,您可以从这里下载。 下面你会发现演示的源代码:

php + jqgrid +导出为ex​​cel

虽然这是一个PHP解决scheme,它的核心似乎是在Javascript中,如果有任何帮助。

您可以使用Office XML格式(http://en.wikipedia.org/wiki/Microsoft_Office_XML_formats)&#x3002; 唯一的缺点是输出将是一个XML文件,而不是一个二进制文件。 但是,它的打开方式与正常的.xls文件完全相同。

我以前的做法是以我需要的格式对Excel进行逆向工程,然后将其保存为.xml格式,在Notepad ++中打开它,并找出标题,表格(从网格转换而来),最后是页脚

例:

标题(可以硬编码)

 <?xml version="1.0"?> <?mso-application progid="Excel.Sheet"?> <Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" xmlns:html="http://www.w3.org/TR/REC-html40"> <DocumentProperties xmlns="urn:schemas-microsoft-com:office:office"> <Author>phpGrid.com</Author> <Created></Created> <LastSaved></LastSaved> <Version></Version> </DocumentProperties> <ExcelWorkbook xmlns="urn:schemas-microsoft-com:office:excel"> <WindowHeight>768</WindowHeight> <WindowWidth>1024</WindowWidth> <WindowTopX>0</WindowTopX> <WindowTopY>0</WindowTopY> <ProtectStructure>False</ProtectStructure> <ProtectWindows>False</ProtectWindows> </ExcelWorkbook> <Styles> <Style ss:ID="Default" ss:Name="Normal"> <Alignment ss:Vertical="Bottom" /> <Borders/> <Font ss:FontName="Arial" ss:Size="8" /> <Interior/> <NumberFormat /> <Protection /> </Style> <Style ss:ID="sHyperlink" ss:Name="Hyperlink"> <Font ss:Color="#0000FF" ss:Underline="Single" /> </Style> <Style ss:ID="sDate"> <NumberFormat ss:Format="Short Date"/> </Style> <Style ss:ID="sNumber"> <NumberFormat/> </Style> <Style ss:ID="sHeader"> <Font ss:Family="Arial" ss:Bold="1" /> </Style> <Style ss:ID="sDecimal"> <NumberFormat ss:Format="Fixed"/> </Style> </Styles><Worksheet ss:Name="Sheet1"> 

Body(这是从datagrid转换而来的表格,需要dynamic生成)

 <Table ss:ExpandedColumnCount="7" ss:ExpandedRowCount="328" x:FullColumns="1" x:FullRows="1"><Row><Cell ss:StyleID="sHeader"><Data ss:Type="String">Order No.</Data></Cell><Cell ss:StyleID="sHeader"><Data ss:Type="String">Order Date</Data></Cell><Cell ss:StyleID="sHeader"><Data ss:Type="String">Shipped Date</Data></Cell><Cell ss:StyleID="sHeader"><Data ss:Type="String">status</Data></Cell><Cell ss:StyleID="sHeader"><Data ss:Type="String">comments</Data></Cell><Cell ss:StyleID="sHeader"><Data ss:Type="String">Customer No.</Data></Cell></Row> <Row><Cell ss:StyleID="sNumber"><Data ss:Type="Number">0</Data></Cell><Cell><Data ss:Type="String">2010-08-20 00:00:00</Data></Cell><Cell><Data ss:Type="String"></Data></Cell><Cell><Data ss:Type="String">Open</Data></Cell><Cell><Data ss:Type="String">foo</Data></Cell><Cell ss:StyleID="sNumber"><Data ss:Type="Number">123456</Data></Cell></Row> <Row><Cell ss:StyleID="sNumber"><Data ss:Type="Number">10100</Data></Cell><Cell><Data ss:Type="String">2003-01-06 00:00:00</Data></Cell><Cell><Data ss:Type="String">2003-01-10 00:00:00</Data></Cell><Cell><Data ss:Type="String">Shipped</Data></Cell><Cell><Data ss:Type="String">foo</Data></Cell><Cell ss:StyleID="sNumber"><Data ss:Type="Number">363</Data></Cell></Row> <Row><Cell ss:StyleID="sNumber"><Data ss:Type="Number">10101</Data></Cell><Cell><Data ss:Type="String">2003-01-18 00:00:00</Data></Cell><Cell><Data ss:Type="String">2003-01-22 00:00:00</Data></Cell><Cell><Data ss:Type="String">Shipped</Data></Cell><Cell><Data ss:Type="String">Check on availability.</Data></Cell><Cell ss:StyleID="sNumber"><Data ss:Type="Number">128</Data></Cell></Row></Table> 

页脚(可以硬编码)

 <WorksheetOptions xmlns="urn:schemas-microsoft-com:office:excel"> <Print> <ValidPrinterInfo /> <HorizontalResolution>800</HorizontalResolution> <VerticalResolution>0</VerticalResolution> </Print> <Selected /> <Panes> <Pane> <Number>3</Number> <ActiveRow>1</ActiveRow> </Pane> </Panes> <ProtectObjects>False</ProtectObjects> <ProtectScenarios>False</ProtectScenarios> </WorksheetOptions> </Worksheet> </Workbook> 

您可以简单地对页眉和页脚XML进行硬编码,只有主体将被dynamic生成。 如果你需要alignment和其他需要的样式。 再次尝试相同的“反向”工程方法,找出需要添加到XML中的东西。

我发现这种方式的一个优点是,您不需要依赖API,因为从字面上看,所有东西都可以被embedded到一个string中。 它也适用于不同的编程语言。 可能不像API那样灵活或强大,但对于数据网格,只有表,行和列是足够的。 至less对于我来说。
