C＃导出为Excel UTF-8问题

我想出口索姆数据到XLS ，但似乎有UTF-8编码的问题。 它输出正常，我得到Excel文件应该看，但是当插入的数据有特殊字符，在这种情况下，丹麦字符如æ ， ø和å ，那么该文件是有点结果。 当我尝试在Excel中打开它时，出现读取文件时出现问题的消息，并将问题提及为设置spreadseet 。

我在几个通过validation的在线validation服务中运行了结果XMLvalidation。 当我在Notepad ++ XMLvalidation器中运行它时，在第一个发现的特殊字符（它是Å ）中出现错误：XX行的XMLparsing错误：input不正确UTF-8，指示编码！

有人能指出那个男人吗？ 我应该在哪里指出编码？

以下是结果XML的相关部分：

<?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"> <Created>2006-09-25T13:34:53Z</Created> <LastSaved>2014-05-20T18:04:40Z</LastSaved> <Version>12.00</Version> </DocumentProperties> <OfficeDocumentSettings xmlns="urn:schemas-microsoft-com:office:office"> <RemovePersonalInformation/> </OfficeDocumentSettings> <ExcelWorkbook xmlns="urn:schemas-microsoft-com:office:excel"> <WindowHeight>7875</WindowHeight> <WindowWidth>14895</WindowWidth> <WindowTopX>360</WindowTopX> <WindowTopY>300</WindowTopY> <ProtectStructure>False</ProtectStructure> <ProtectWindows>False</ProtectWindows> </ExcelWorkbook> <Styles> ... </Styles> <Worksheet ss:Name="Ark1"> <Names> <NamedRange ss:Name="GIS34_Skade_V1_alle_koder" ss:RefersTo="=Ark1!R5C2:R28C2"/> </Names> <Table ss:ExpandedColumnCount="16" ss:ExpandedRowCount="34" x:FullColumns="1" x:FullRows="1" ss:StyleID="s16" ss:DefaultRowHeight="15"> <Column ss:StyleID="s16" ss:AutoFitWidth="0" ss:Width="30"/> <Column ss:StyleID="s16" ss:AutoFitWidth="0" ss:Width="135" ss:Span="2"/> <Column ss:Index="5" ss:StyleID="s19" ss:AutoFitWidth="0" ss:Width="30"/> <Column ss:StyleID="s16" ss:AutoFitWidth="0" ss:Width="135"/> <Column ss:StyleID="s19" ss:AutoFitWidth="0" ss:Width="30"/> <Column ss:StyleID="s16" ss:AutoFitWidth="0" ss:Width="135"/> <Column ss:StyleID="s19" ss:AutoFitWidth="0" ss:Span="3"/> <Row ss:AutoFitHeight="0" ss:Height="30" ss:StyleID="s18"> <Cell ss:StyleID="s33"/> <Cell ss:StyleID="s126"><Data ss:Type="String">LE34</Data></Cell> <Cell ss:StyleID="s87"><Data ss:Type="String">Kunde:</Data></Cell> <Cell ss:StyleID="s32"><Data ss:Type="String">Assens Kommune</Data></Cell> </Row> <Row ss:AutoFitHeight="0" ss:Height="30" ss:StyleID="s18"> <Cell ss:StyleID="s33"/> <Cell ss:StyleID="s128"><Data ss:Type="String">GIS34</Data></Cell> <Cell ss:StyleID="s87"><Data ss:Type="String">Kodeliste:</Data></Cell> <Cell ss:StyleID="s32"><Data ss:Type="String">Arkil Århus V2</Data></Cell> <!-- Error occures in this line first because of the **Å** char --> </Row> <Row ss:AutoFitHeight="0"> <Cell ss:StyleID="s33"/> <Cell ss:MergeAcross="6" ss:StyleID="s37"><Data ss:Type="String">Udformning af lagkontrol: </Data></Cell> <Cell ss:StyleID="s16"/> <Cell ss:StyleID="s16"/> <Cell ss:StyleID="s16"/> <Cell ss:StyleID="s16"/> </Row> ... <Row ss:AutoFitHeight="0"> <Cell ss:Index="2" ss:StyleID="s29"><NamedCell ss:Name="GIS34_Skade_V1_alle_koder"/></Cell> <Cell ss:StyleID="s30"><Data ss:Type="String">Billede 3 (filename)</Data></Cell> <Cell ss:StyleID="s30"/> <Cell ss:StyleID="s16"/> <Cell ss:StyleID="s20"/> <Cell ss:StyleID="s16"/> <Cell ss:StyleID="s20"/> <Cell ss:StyleID="s16"/> <Cell ss:StyleID="s16"/> <Cell ss:StyleID="s16"/> <Cell ss:StyleID="s16"/> </Row> </Table> <WorksheetOptions xmlns="urn:schemas-microsoft-com:office:excel"> <PageSetup> <Header x:Margin="0.31496062992125984"/> <Footer x:Margin="0.31496062992125984"/> <PageMargins x:Bottom="0.74803149606299213" x:Left="0.70866141732283472" x:Right="0.70866141732283472" x:Top="0.74803149606299213"/> </PageSetup> <Print> <ValidPrinterInfo/> <PaperSizeIndex>9</PaperSizeIndex> <HorizontalResolution>600</HorizontalResolution> <VerticalResolution>600</VerticalResolution> <Gridlines/> </Print> <Selected/> <FreezePanes/> <FrozenNoSplit/> <SplitHorizontal>7</SplitHorizontal> <TopRowBottomPane>7</TopRowBottomPane> <ActivePane>2</ActivePane> <Panes> <Pane> <Number>3</Number> </Pane> <Pane> <Number>2</Number> <ActiveRow>26</ActiveRow> <ActiveCol>13</ActiveCol> </Pane> </Panes> <ProtectObjects>False</ProtectObjects> <ProtectScenarios>False</ProtectScenarios> </WorksheetOptions> <QueryTable xmlns="urn:schemas-microsoft-com:office:excel"> <Name>GIS34 Skade V1_alle koder</Name> <AutoFormatFont/> <AutoFormatPattern/> <QuerySource> <QueryType>Text</QueryType> <TextWizardSettings> <Name x:HRef="C:\Temp\dummy.txt"/> <Decimal>,</Decimal> <ThousandSeparator>.</ThousandSeparator> <TrailingMinusNumbers/> <FormatSettings> <FieldType>AutoFormat</FieldType> </FormatSettings> <Delimiters> <Tab/> </Delimiters> </TextWizardSettings> <VersionLastEdit>3</VersionLastEdit> <VersionLastRefresh>3</VersionLastRefresh> </QuerySource> </QueryTable> </Worksheet> </Workbook> 

这里是我如何导出：

 context.Response.ContentType = "application/excel"; context.Response.AddHeader("Content-disposition", "attachment; filename=\"report.xls\""); context.Response.ContentEncoding = new System.Text.UTF8Encoding(); context.Response.Write(excel); 

更新1：

我现在将导出代码更改为以下string编码为UTF-8， 没有得到好的结果：

 string excel = header.ToString() + styles.ToString() + title.ToString() + content.ToString() + footer.ToString(); context.Response.ContentType = "application/excel"; context.Response.AddHeader("Content-disposition", "attachment; filename=\"report.xls\""); //context.Response.ContentEncoding = new System.Text.UTF8Encoding(); byte[] bytes = Encoding.Default.GetBytes(excel); context.Response.Write(Encoding.UTF8.GetString(bytes)); 

更新2：

再次改变（由@Luaanbuild议），但仍然是一样的：

 string excel = header.ToString() + styles.ToString() + title.ToString() + content.ToString() + footer.ToString(); context.Response.ContentType = "application/excel"; context.Response.AddHeader("Content-disposition", "attachment; filename=\"report.xls\""); HttpContext.Current.Response.BinaryWrite(UTF8Encoding.UTF8.GetBytes(excel)); 

Answer 1

 <?xml version="1.0"?> 

应该

 <?xml version="1.0" encoding="utf-8"?> 

相反 – 确保XML实际上是UTF-8。 设置Content-Encoding HTTP标题不会帮助你。

编辑 ：您的更新不编码任何东西（事实上，你可能会引入更多的问题，这种方式），你发送它再次作为string。

相反，你想写的byte[] ：

 HttpContext.Current.Response.BinaryWrite(UTF8Encoding.UTF8.GetBytes(excel)); 

Answer 2

尝试使用一些库，可以做到这一点，你会节省很多时间，例如

• http://closedxml.codeplex.com/
• http://freenetexcel.codeplex.com/
• http://epplus.codeplex.com/
• http://npoi.codeplex.com/

Answer 3

解决这个问题的简单方法是在HttpContext.Current.Response中设置charset，如下所示：

  HttpContext.Current..Response.Charset = "UTF-8"; 

代码最完整的部分：

  curContext.Response.Clear(); curContext.Response.Buffer = true; curContext.Response.Charset = "UTF-8"; curContext.Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; curContext.Response.AddHeader("content-disposition", "attachment;filename=" + FileName + ".xlsx");
