我正在将 CSV 文件流式传输到 Internet Explorer。在流式传输结束时，Internet Explorer 会显示一个打开、保存和取消对话框。如果您在显示对话框后等待 30 秒并单击“打开”按钮，Internet Explorer 将不执行任何操作。这在 Firefox 中运行良好。除了 Flush 和 End on the Response，我还需要其他命令吗？这是我拥有的代码：

protected void Page_Load(object sender, EventArgs e)
{
    DataTable dt = ReportService.GetAllOwnerAircraftPaymentInformation();

    //Generate the report
    using (MemoryStream stream = new MemoryStream())
    {
        StreamWriter writer = new StreamWriter(stream);
        CsvHelper csvHelper = new CsvHelper();

        csvHelper.DataTableToCsv(writer, dt);

        writer.Flush();

        //Send it to the browser
        stream.Seek(0, SeekOrigin.Begin);

        string fileName = string.Format("MassAVRMSDataExport{0}.csv", DateTime.Now.ToString("yyyyMMddhhmmss"));

        Response.ClearHeaders();
        Response.Clear();
        Response.ContentType = "application/octet-stream";
        Response.AddHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\"");
        Response.AddHeader("Content-Length", stream.Length.ToString(CultureInfo.InvariantCulture));
        StreamHelper.CopyStream(stream, Response.OutputStream);
        Response.Flush();
        Response.End();
    }
}

尝试设置：

stream.Position = 0;
StreamHelper.CopyStream(stream, Response.OutputStream);

Greg 使用 IE Explorer 时需要添加以下内容

Response.ContentType = "application/download"
