我正在ASP.NET站点上进行一些Excel导出。 除了编码之外,一切都有效。当我在Excel中打开它时,它看起来像这样:
Eingabe KostenjeGerätGerät: Gerätebezeichnung: BetrbsmittelHeizölinâ€:4 Dieselverbrauchinâ€: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();
我已经尝试过显式设置编码..但没有发生任何变化:
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();
出了什么问题?

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(在表示所用编码的文件的开头)。 / p>
所以我这样做了,它对我有用:
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();

您是否尝试在HTML中的元标记中设置编码?
<meta http-equiv="content-type" content="application/xhtml+xml; charset=UTF-8" />
Excel不会看到响应标头,因此它不会知道Response.Encoding
是什么。元标记允许它找出。

对于需要UTF8的情况......
FileInfo dataExportFile = new FileInfo(dsExport.Tables[0].Rows[0]["DataExportFile"].ToString());
Response.Clear();
Response.ContentType = "application/ms-excel";
Response.AddHeader("Content-Disposition", "attachment;filename=" + dataExportFile.Name);
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.BinaryWrite(System.Text.Encoding.UTF8.GetPreamble());
Response.TransmitFile(dataExportFile.FullName);

我对西班牙语字符有同样的问题并用这行代码解决了。
response.ContentEncoding = System.Text.Encoding.Default ;
希望这会有所帮助

您可以尝试使用“Server.HtmlDecode”来解码像“João”这样的单词
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e){
String wrong = "João";
String corrected = Server.HtmlDecode(wrong);}
