ASP.NET从内存而不是从文件中流内容

我在ProcessResponse中使用类似于以下的东西来输出之前在数据库表中构造的CSV …

public void ProcessRequest(HttpContext context)
{
    HttpResponse response = context.Response;
    HttpRequest request = context.Request;

    //Get data to output here...

    //Turn off Caching and enforce a content type that will prompt to download/save.
    response.AddHeader("Connection","close");
    response.AddHeader("Cache-Control","private");
    response.ContentType = "application/octect-stream";

    //Give the browser a hint at the name of the file.
    response.AddHeader("content-disposition",string.Format("attachment; filename={0}",_filename));

    //Output the CSV here...
    foreach(BatchDTO.BatchRecordsRow row in dtoBatch.BatchRecords)
        response.Output.WriteLine(row.Data);

    response.Flush();
    response.Close();
}

有许多库可以使生成CSV变得更容易,您应该只能将它传递给Response.OutputStream以使其写入那里而不是文件流.
