Question

首先，这是我的代码：

DataTable usersReport = reportsService.GenerateUsersReport();

var grid = new GridView();
grid.DataSource = usersReport;
grid.DataBind();

Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=UsersReport.xls");
Response.ContentType = "application/ms-excel";

Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);

grid.RenderControl(htw);

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

正如您所看到的，我只是以简单的方式生成有关用户的报告。当我在excel中打开此文件时，特殊字符存在问题，例如ś,ż,ź,ó,ę,ą等。

而不是Imię我可以看到ImiÄ™。与GyÅ¼yÅ„ski

相同的问题

我该如何解决？

编辑：

添加以下行：

Response.Charset = "";
Response.ContentEncoding = System.Text.Encoding.Default;

现在Imię看起来像Imiê。总之 - 仍然没有

Answer 1

你尝试过这个吗？可能是excel文件的标题缺少字节顺序标记（BOM）序列，请尝试使用GetPreamble

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

StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);

grid.RenderControl(htw);

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

Answer 2

经过一番调查后，我发现了一个解决方案。重要的是源HTML的<meta>标记。

这样一行：

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

应如下所示：

Response.Output.Write("<meta http-equiv='Content-Type' content='application/vnd.ms-excel; charset=utf-8'>" + sw.ToString());

以下代码将对特殊字符使用Wrk并将Excel中的null删除为 从数据表中，我们正在创建同时写入特殊字符的Excel

主要技巧是使其成为UTF-32并应用BinaryWrite

    public void DataTableToExcel(DataTable dt)
    {
        string attachment = "attachment; filename=download.xls";
        Response.ClearContent();
        Response.AddHeader("content-disposition", attachment);
    Response.ContentEncoding = System.Text.Encoding.UTF32;
    Response.BinaryWrite(System.Text.Encoding.UTF32.GetPreamble());
        Response.ContentType = "application/vnd.xls";

        string tab = "";
        foreach (DataColumn dc in dt.Columns) // table col
        {
            Response.Write(tab + dc.ColumnName);
            tab = "\t";
        }
        Response.Write("\n");

        int i;
        string content = "";
        foreach (DataRow dr in dt.Rows) // Data Row by row
        {
            tab = "";
            for (i = 0; i < dt.Columns.Count; i++)
            {
                content = dr[i].ToString();
                content = content.Replace(System.Environment.NewLine, " ");
                Response.Write(tab + content);
                tab = "\t";
            }
            Response.Write("\n");
        }
        Response.End();
    }
