SecurityExcepti on in Console Application on GetCommandLineA rgs()

[jwgoerlich]

I wrote a simple VB.Net console application. It accepts command line
parameters and creates a folder structure. It works on the local file
system without a problem

If I run the console app from a UNC or network share, I get a
SecurityExcepti on on the following line:

Dim args() As String = Environment.Get CommandLineArgs ()

Has anyone seen this before? Is there something special I need to do
for console applications on UNC paths?

Thanks in advance,

I suggest you get the command line args as parameters to your Main
method instead:

Shared Sub Main(ByVal CmdArgs() As String)

Thank you, Mattias. While I cannot create sub main as shared in the
Console module, your solution works otherwise. That is one big step
forward.

The next problem is that I am getting a SecurityExcepti on when I go to
access the remote file system. I am going over a UNC path using the
domain Administrator account. I have verified that this account is a
member of the BUILTIN\Adminis trators on the computer I am accessing,
and that it has full share and NTFS rights. My console app works if I
copy it to that computer and run it locally. Unfortunately, I must run
it over UNC.

Can you give me some pointers on this one, too? Do .Net console
applications typically not perform well over UNC?
