在网络上打开文件asp .net [英] Openning files on the network asp .net

问题描述

嗨
我需要在网络上打开文件的帮助.我从数据库创建了一个文件，但无法打开它.错误消息:该进程无法访问文件"\\ IP地址\ Templates \ testing.png"，因为该文件正被另一个进程使用.

有没有一种无需使用该过程即可打开文件的方法.在我的本地计算机上没有问题，但是在IIS上它们无法打开.

这是我的代码:

Hi
I need help with openning a file on the network. I create a file from the database and couldn''t open it. The error says: The process cannot access the file ''\\IP Address\Templates\testing.png'' because it is being used by another process.

Is there a way to open a file without using the process. On my local machine there is no problem, but on IIS they fail to open.

Here is my code:

//Getting file from network
CustomerDocument custdoc = new CustomerDocument(DocumentID);
//Return the stream
byte[] filedata = custdoc.imgCustomerDocumentStream;
//Return filename, it has extension
string filename = custdoc.nvFileName;

//Saving on the server, filepath from the webconfig
string filepath = @"\\IP Addresss\\Templates";

try
   {
//Write stream to file
 using (FileStream fs = new FileStream(di + "\\" + filename, FileMode.Create,FileAccess.ReadWrite))
   {
   fs.Write(filedata, 0, filedata.Length);//write the file
   fs.Seek(0, SeekOrigin.Begin);
    }
//Trying to open a file
     ProcessStartInfo psi = new ProcessStartInfo();
     psi.FileName = di + "\\" + filename;
     Process.Start(psi);
    }
    catch (Exception ex)
    {
    //  throw;
     lblStatus.Text = ex.Message;
    }

预先谢谢您.

Thanking you in advance.

Process.Start在Asp中不起作用.网络构建(在inetmgr中) [

...just find part-answere here.

Process.Start not working in Asp .net build(Under inetmgr)[^]

"If you take the msdn page of ProcessStartInfo you'' ll see that there are special security notes. The reason that it doesn'' t work is that the asp page isn'' t authorized to execute other assemblies and could also be denied access to the directory" . Now is there a way to open the file without using a process?
