推荐答案

如果你只是想从一个文本文件中的数据库将被下载到用户本地计算机返回一些数据，创建一个动作在控制器这样的样本：

If you just want to return some data from the database in a text file that will be downloaded to user's local computer, create an Action in your Controller like in this sample:

using System.IO;
using System.Text;      

public class SomeController {

    // this action will create text file 'your_file_name.txt' with data from
    // string variable 'string_with_your_data', which will be downloaded by
    // your browser
    public FileStreamResult CreateFile() {
        //todo: add some data from your database into that string:
        var string_with_your_data = "";

        var byteArray = Encoding.ASCII.GetBytes(string_with_your_data);
        var stream = new MemoryStream(byteArray);

        return File(stream, "text/plain", "your_file_name.txt");   
    }

}

，那么你可以创建一个 ActionLink的以在该操作您的查看将触发文件下载：

then you can create an ActionLink to that action on your View which will trigger file download:

@Html.ActionLink("Download Text File", "CreateFile", "SomeController ")
