问题描述

我正在使用一个小型应用程序.

我有一张包含EmpID，Name和FileNo的表.

示例数据如下.

EmpID EmpName文件号
101 A 9001
102 B 9002
103 C 9003
104 D 9004


每个月我都会得到PDF文件.此文件名完全基于数据库"FileNo".

例如9001.pdf
9002.pdf ...等.

当用户单击链接按钮时，他想打开位于特定文件夹中的相应pdf文件.


例如，

当员工101时，他想打开9001.pdf.其余的应该限制打开..

单击链接按钮时如何执行此操作.

请帮助...

推荐答案

我给您的功能是，您只需传递文件名和带有路径的文件名，便会打开pdf文件.
您必须检查该文件是否存在.我没有在此程序中完成它

i am giving you function in which you just pass the filename and filename with path it will open the pdf file.
you have to check that this file is exist or not. i have not done it in this programm

private void OpenPDF(string sFilename,string  strPdfFileWithPath)
    {
    byte[] bytedata=System.IO.File.ReadAllBytes(strPdfFileWithPath);
        Response.Clear();
        Response.ContentType = "application/pdf";
        Response.AddHeader("Content-Disposition", "attachment; filename=\"" + sFilename + "\"");
        Response.Flush();
        Response.BinaryWrite(bytedata);
        Response.End();
    }
