How to get filenames from shared network directory?

[Goran Djuranovic]

Hi All,
The following code works fine in VB.NET (Windows app and Web app projects) when converted to VB.
It also works fine in C#, BUT only in Windows app project. All tested applications contain only this code on loading of the application (form).

Why does it not work in C# Web app project? Could this be a bug? I am using VS.NET 2003 EA

System.IO.Direc toryInfo di = new System.IO.Direc toryInfo("\\\\M yServer\\MyFold er\\MySubFolder 1\\MySubFolder2 \\MySubFolder3\ \MySubFolder4\\ ");
System.IO.FileI nfo[] fi = new System.IO.FileI nfo[500];
fi = di.GetFiles();
foreach (System.IO.File Info f in fi)
{
Response.Write( f.FullName + "<br>");
// Console.WriteLi ne(f.FullName);
}

No, it is not a bug, its all about security.

When your code executes in the web app context you work under ASP.NET account, which may not have access to network share.

Hi Vadym,
Thanks for your response.

So, are you saying that security is different in C# than VB?
I am asking this because the same code works on ASP.NET application written
in VB.NET. Read my previous post again.

Can you post VB version of code, and define how the code written in C# is not working, is there any exception being thrown or smth else?

You are running as the ASP.NET account so you need to have permissions
to do that.
