ASP.NET流内容而不是从文件流内容 [英] ASP.NET stream content from memory and not from file

问题描述

用户已经选择下载GridView内容的csv文件表示形式。有没有人知道如何做到这一点，而不保存文件到服务器，而只是从内存流式传输给用户？

The users have requested the option to "download" a csv file representation of GridView contents. Does anyone know how to do this without saving the file to the server but rather just streaming it to the user from memory?

谢谢

推荐答案

我创建了一个StringBuilder并使用以下代码将内容转储到Response对象中（csv是StringBuilder变量）。

I created a StringBuilder and dump the contents to the Response object using the following code ("csv" is the StringBuilder variable).

    Response.ContentType = @"application/x-msdownload";
    Response.AppendHeader("content-disposition", "attachment; filename=" + FILE_NAME);

    Response.Write(csv.ToString());
    Response.Flush();
    Response.End();
