问题描述

我正试图将som数据导出到 xls ，但似乎对UTF-8编码有问题. 它可以很好地导出，并且我可以看到Excel文件，但是在插入的数据包含特殊字符的情况下，在这种情况下，丹麦字符为æ，ø和å，则文件已损坏.当我尝试在Excel中打开它时，我收到一条消息，指出在读取文件时出现问题，并在设置点播机中提及了该问题.

I'm tring to export som data to xls, but seem to have a problem with the UTF-8 encoding. It exports fine and I get the Excel file looking at it should, but when the inserted data has special characters, in this case, danish characters as æ, ø and å, then the file is somewhat currupted. When I try to open it in Excel, I get a message that a problem occured in reading the file, and mentions the problem as Setting of the spreadseet.

我在少数通过验证的在线验证服务中对结果XML进行了验证.当我在Notepad ++ XML验证程序中运行它时，我在第一个发现特殊字符(为Å)的错误中发现了一个错误，该字符表示:在第XX行出现 XML解析错误:输入不正确的UTF -8，指示编码！

I ran validation of the resulted XML in few online validation services which passed the validation. When I ran it in the Notepad++ XML validator, I got an error in the først found special char (which was Å) which says: XML Parsing error at line XX: Input is not proper UTF-8, Indicate encoding!

有人可以指出其含义吗? 我应该在哪里指示编码?

Can someone point out what that meens? where should I indicate the encoding?

以下是生成的XML的相关部分:

Here are the relevant parts of the resulting XML:

这是我的出口方式:

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代码，将字符串编码为UTF-8，结果否:

I now changed the export code to the following where I encode the string as UTF-8, getting no good results:

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:

再次更改(@Luaan建议)，但仍然相同:

Changes again to this (suggested by @Luaan), but still the same:

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));

推荐答案

<?xml version="1.0"?>

应该是

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

代替-并确保XML实际上是UTF-8.设置Content-Encoding HTTP标头将无济于事.

instead - and make sure the XML is actually in UTF-8. Setting the Content-Encoding HTTP header will not help you.

编辑:您的更新未编码任何内容(实际上，您可能会以这种方式引入更多问题)，您将其重新发送为字符串.

EDIT: Your update doesn't encode anything (in fact, you're likely to introduce even more problems that way), you're sending it as string again.

相反，您要编写byte[]:

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