c# - 创建文本文件并下载

Question

我正在尝试写入内存中的文本文件，然后下载该文件而不将文件保存到硬盘。我正在使用 StringWriter 来写入内容:

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

我该如何下载这个文件？

编辑:答案的组合给了我我的解决方案。在这里:

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();

这为我解决了:

        MemoryStream ms = new MemoryStream();
        TextWriter tw = new StreamWriter(ms);
        tw.WriteLine("Line 1");
        tw.WriteLine("Line 2");
        tw.WriteLine("Line 3");
        tw.Flush();
        byte[] bytes = ms.ToArray();
        ms.Close();

        Response.Clear();
        Response.ContentType = "application/force-download";
        Response.AddHeader("content-disposition", "attachment;    filename=file.txt");
        Response.BinaryWrite(bytes);
        Response.End();
