带Response.WriteFile的Crystal Report [英] Crystal Report with Response.WriteFile

问题描述

Hello Everyone，



我想根据用户选择文件格式生成并保存Crystal Report（来自下拉列表。

  Dim  filename  As  字符串 = ds.Tables（ 0 ）。行（ 0 ）（  reportoutfile）
 Response.ContentType =   applicaiton / octet-stream 
 Response.WriteFile（??）

第1行：reportoutfile是具有文件名的参数。

第3行：Response的参数是什么。 WriteFile？



我的报告路径应该在哪里？

解决方案

一般来说，如果需要任何文件下载以下代码可以做到这一点

  string  file_path = Server.MapPath（ 〜/文件/ + FILE_NAME）; 
 HttpContext.Current.Response.ContentType =   application / octet-stream; 
 HttpContext.Current.Response.AddHeader（  Content-Disposition，  attachment; filename = \ + file_Name +   \）; 
 HttpContext.Current.Response.TransmitFile（file_path）; 
 HttpContext.Current.Response.End（）; 
 

对于水晶报告，我猜你需要借助Crystal Report查看器控件创建水晶报告文件。
