创建文本文件，并下载 [英] Create text file and download

问题描述

我试图写入到内存中的文本文件，然后下载文件，而无需将文件保存到硬盘。我使用了的StringWriter 写的内容：

 的StringWriter oStringWriter =新的StringWriter（）;
oStringWriter.Write（这是内容）;
 

我如何再下载此文件？

编辑：
这是这给了我答案的解决方案组合。在这里，它是：

 的StringWriter oStringWriter =新的StringWriter（）;
oStringWriter.WriteLine（1号线）;
Response.ContentType =text / plain的;Response.AddHeader（内容处置，附件;文件名=+的String.Format（社员{0} .csv，下载的String.Format（{0：DDMMYYYY}，DateTime.Today）））;
Response.Clear（）;使用（StreamWriter的作家=新的StreamWriter（Response.OutputStream，Encoding.UTF8））
{
    writer.Write（oStringWriter.ToString（））;
}
到Response.End（）;
 

解决方案

而不是存储在内存中的数据，然后将其发送到响应流中，你可以直接将其写入响应流：

 使用（StreamWriter的作家=新的StreamWriter（Response.OutputStream，Encoding.UTF8））{
  writer.Write（这是内容）;
}
 

该示例使用UTF-8编码，你应该改变，如果你使用的是一些其他的编码。

I'm trying to write to a text file in memory and then download that file without saving the file to the hard disk. I'm using the StringWriter to write the contents:

StringWriter oStringWriter = new StringWriter();
oStringWriter.Write("This is the content");

How do I then download this file?

EDIT: It was combination of answers which gave me my solution. Here it is:

StringWriter oStringWriter = new StringWriter();
oStringWriter.WriteLine("Line 1");
Response.ContentType = "text/plain";

Response.AddHeader("content-disposition", "attachment;filename=" + string.Format("members-{0}.csv",string.Format("{0:ddMMyyyy}",DateTime.Today)));
Response.Clear();

using (StreamWriter writer = new StreamWriter(Response.OutputStream, Encoding.UTF8))
{
    writer.Write(oStringWriter.ToString());
}
Response.End();

解决方案

Instead of storing the data in memory and then sending it to the response stream, you can write it directly to the response stream:

using (StreamWriter writer = new StreamWriter(Response.OutputStream, Encoding.UTF8)) {
  writer.Write("This is the content");
}

The example uses the UTF-8 encoding, you should change that if you are using some other encoding.
