网页的SaveFileDialog等效项 [英] SaveFileDialog equivalent for a webpage

问题描述

从高层次看，这似乎并不像火箭科学，但事实证明这是一个挑战.我对c#Windows窗体开发更加熟悉.我现在正在创建一个网页，并且需要将等效于Windows形式的SaveFileDialog功能合并到该网页中.至少，我需要使最终用户能够选择自己的文件路径和名称，并为其保存GridView中的数据.我有什么选择?

At a high-level this does not seem like rocket science, but it is proving to be a challenge. I am more familiar with c# windows form development. I am now creating a webpage and need to incorporate the equivalent of windows form SaveFileDialog functionality into the webpage. At the very least, I need to give the end user the ability to select their own file path and name for which data from a GridView will be saved. What are my options?

推荐答案

我想您想要这样的东西:

I guess you want something like this:

FileStream sourceFile = new FileStream(Server.MapPath(@"FileName"), FileMode.Open); 
float FileSize; 
FileSize = sourceFile.Length; 
byte[] fileContent = new byte[(int)FileSize]; 
sourceFile.Read(fileContent, 0, (int)sourceFile.Length); 
sourceFile.Close(); 
Response.ClearContent(); 
Response.ClearHeaders(); 
Response.Buffer = true; 
Response.ContentType = "application/octet-stream"; 
Response.AddHeader("Content-Length", fileContent.Length.ToString()); 
Response.AddHeader("Content-Disposition", "attachment; filename=" + FileName); 
Response.BinaryWrite(fileContent); 
Response.Flush(); 
Response.End();
