In einigen F��llen muss mit den Dateizugriffs-Rechten gearbeitet werden. So mmuss die ACL (Access Control List) ausgelesen und angepasst werden. Hier ein Code-Snippet, welches den Umgang mit den entsprechenden Klassen aus dem .NET Framework 2.0 zeigt. Kurze Beschreibungen gibt es als Code-Comment.
// Creating a testfile
Console.WriteLine("Creating XML File");
// Getting Access Control List (ACL) of the file
FileSecurity fSec = File.GetAccessControl(@"C:temptest.xml");
// Get Access Right Type
Type accessRightType = fSec.AccessRightType;
Console.WriteLine("AccessRightType: " + accessRightType.FullName);
// Get Owner of the file
string fileOwner = fSec.GetOwner(typeof(System.Security.Principal.NTAccount)).Value;
Console.WriteLine("Owner: " + fileOwner + System.Environment.NewLine);
// Get Access Rules of the file
AuthorizationRuleCollection authRuleColl =
fSec.GetAccessRules(true, true, typeof(System.Security.Principal.NTAccount));
// Iterate through all Access Rules
foreach (FileSystemAccessRule rule in authRuleColl)
{
Console.WriteLine("Control Type : " + rule.AccessControlType.ToString());
Console.WriteLine("Identity : " + rule.IdentityReference.Value);
Console.WriteLine("Inheritance Flags: " + rule.InheritanceFlags.ToString());
Console.WriteLine("Is Inherited : " + rule.IsInherited.ToString());
Console.WriteLine("Propagation Flags: " + rule.PropagationFlags.ToString());
Console.WriteLine("File System Right: " + rule.FileSystemRights.ToString());
Console.WriteLine(System.Environment.NewLine);
}
Console.WriteLine("Adding new Rule");
// Adding a new rule to the file's Access Control List
fSec.AddAccessRule(new
System.Security.AccessControl.FileSystemAccessRule(
System.Security.Principal.WindowsIdentity.GetCurrent().Name,
System.Security.AccessControl.FileSystemRights.Read &
System.Security.AccessControl.FileSystemRights.Write,
System.Security.AccessControl.AccessControlType.Allow));
Console.WriteLine("Setting nun FileSecurity");
// Save Access Control List
File.SetAccessControl(@"C:temptest.xml", fSec);
