Copy from network

[NewsBot]

Hi. I’m new when it comes to C# and have some problems with a application I’m developing.*
The scenario is as follows: I want to copy all new files from a directory on our network to the hard drive. Here’s the kicker… *The program will be running from the network drive. The user navigates to the network drive and run my app that copies all the new files in that directory to a specified location on their computer.

I got a lot of tips this post: from http://channel9.msdn.com/ShowPost.aspx?PostID=340403The problem is that the line marked problem generates a SecurityExeption.

The code looks something like this.

public FileCopy(string targetPath)
{
****** try
****** {
***********//sorcefiler
********** DirectoryInfo sourceDir = new DirectoryInfo(“.”)
********** //Target files
***********DirectoryInfo targetDir = new DirectoryInfo(targetPath);//PROBLEM
******* }
******* catch (Exception e)
******* {
********** MessageBox.Show(e.Message, "Unexpected exception", MessageBoxButtons.OK);
*********** return;
******* }

********** //copy new files
***********this.copyNewFiles(sourceDir, targetDir);
********** //Startar programmet
********** this.startProgram(targetPath);
******* }
static void Main(string[] args)
{
*** FileCopy files = new FileCopy(arg.Replace("L=", ""));
}

The exeption:
“Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral' failed.
…
The action that faild was:
Demand
The type of the first permission that faild was:
System.Security.Permission.FileIOPermission
The zone of the assembly that faild was
Intranet”
Any ideas how to fix it without changing permissions in .NET Framework 2.0 Configuration?
