The following code sample shows how to determine whether the file you are trying to use is already in use or not.


FileIOPermission isAvailable = new FileIOPermission( PermissionState.None);
try
{
isAvailable .SetPathList( FileIOPermissionAccess.Read, fileName);
isAvailable .Demand( ); // does file permit shared reading?
Console.WriteLine( "{0} is O.K. to read.", fileName);
}
catch ( SecurityException _se)
{
MessageBox.Show( _se.Message);
}
