ASP.NET Excel 导出编码问题

本文介绍了ASP.NET Excel 导出编码问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在 ASP.NET 站点上进行一些 Excel 导出.除了编码之外，一切正常.当我在 Excel 中打开它时，它看起来像这样:

I'm doing some Excel Exports on the ASP.NET Site. Everything works except of the Encoding. When I open it in Excel, it looks like this:

Eingabe Kosten je Gerät Gerät:Gerätebezeichnung:Betriebsmittel Heizöl 在 €:4Dieselverbrauch 在 €:4

Eingabe Kosten je Gerät Gerät: Gerätebezeichnung: Betriebsmittel Heizöl in €: 4 Dieselverbrauch in €: 4

这是我的代码:

Response.Clear();
Response.ContentType = "application/ms-excel";
Response.AddHeader("Content-Disposition", "inline;filename=NachkalkGeraete.xls;");
var writer = new HtmlTextWriter(Response.Output);

SomeControl.RenderControl(writer); /* FormView, Table, DataGrid... */

Response.End();

我已经尝试明确设置编码..但没有发生任何变化:

I've already tried explicitly set the Encoding.. but no change occured:

Response.Clear();
Response.ContentType = "application/vnd.ms-excel";
Response.AddHeader("Content-Disposition", "attachment; filename=NachkalkGeraete.xls");

Response.BufferOutput = true;
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.Charset = "UTF-8";
EnableViewState = false;

System.IO.StringWriter tw = new System.IO.StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(tw);

SomeControl.RenderControl(hw);

Response.Write(tw.ToString());
Response.End();

请问怎么了?

推荐答案

好吧，我发现问题可能出在 excel 文件的标题中，它不包含 BOM 字节序列(在代表使用的编码的文件的开头).

Well I found out that the problem could be in the header of the excel file, that it does not contain the BOM byte sequence (at the beginning of the file representing the encoding used).

所以我是这样做的，它对我有用:

So I made it this way and it works for me:

Response.Clear();
Response.AddHeader("content-disposition","attachment;filename=Test.xls");   
Response.ContentType = "application/ms-excel";
Response.ContentEncoding = System.Text.Encoding.Unicode;
Response.BinaryWrite(System.Text.Encoding.Unicode.GetPreamble());

System.IO.StringWriter sw = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter hw = new HtmlTextWriter(sw);

FormView1.RenderControl(hw);

Response.Write(sw.ToString());
Response.End();
