我想将数据从DaraGrid导出到Excel文件中。这些数据是法语的这是我的方法:

public static void ExportGridView( DataGrid dataGrid, string fileName)
    {
        HttpResponse m_Response = HttpContext.Current.Response;
        m_Response.Clear();
        m_Response.AddHeader("content-disposition",
            string.Format("attachment;filename={0}", fileName));
        m_Response.Charset = "";           
        m_Response.ContentType = "application/octet-stream"; //"application/vnd.xls";
        m_Response.ContentEncoding = Encoding.UTF32;
        StringWriter stringWrite = new StringWriter();
        HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
        dataGrid.RenderControl(htmlWrite);
        m_Response.Write(stringWrite.ToString());
        m_Response.End();

}

否则输出的法语格式就不好

(例如)

英语=>英语

兴业银行=>兴业银行

尝试使用 ISO-8859-1 :

public static void ExportGridView(DataGrid dataGrid, string fileName)
{
    var response = HttpContext.Current.Response;
    response.Clear();
    response.AddHeader("content-disposition", string.Format("attachment; filename={0}", fileName));
    var isoEncoding = Encoding.GetEncoding("iso-8859-1");
    response.Charset = isoEncoding.WebName;
    response.ContentType = "application/vnd.ms-excel";
    response.ContentEncoding = isoEncoding;
    using (var writer = new StringWriter())
    using (var htmlWriter = new HtmlTextWriter(writer))
    {
        dataGrid.RenderControl(htmlWriter);
        response.Write(writer.GetStringBuilder().ToString());
    }
    response.End();
}

另一种可能更好的方法是生成整个HTML页面并指定UTF8编码,IMHO更好:

public static void ExportGridView(DataGrid dataGrid, string fileName)
{
    var response = HttpContext.Current.Response;
    response.Clear();
    response.AddHeader("content-disposition", string.Format("attachment; filename={0}", fileName));
    response.Charset = Encoding.UTF8.WebName;
    response.ContentType = "application/vnd.ms-excel";
    response.ContentEncoding = Encoding.UTF8;
    using (var writer = new StringWriter())
    using (var htmlWriter = new HtmlTextWriter(writer))
    {
        dataGrid.RenderControl(htmlWriter);
        string html = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\"><html xmlns=\"http://www.w3.org/1999/xhtml\"><head><title>Test</title><meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" /></head><body>{0}</body></html>";
        response.Write(string.Format(html, writer.GetStringBuilder()));
    }
    response.End();
}

我怀疑他/她使用utf32是有原因的。我很想把这条线完全划掉,看看会发生什么。如果utf8是从Excel到DataGrid的,那么它就可以工作了,我想你是对的,但是它是相反的。这条线甚至可能不是问题。

我更怀疑那些“StringWriter”对象。我不熟悉这些。如果您使用html来移动东西,浏览器不应该能够识别utf32,而是将其视为utf16,这可能是您的问题。
