Security issue needs to be resolved.

[MyCatAlex]

I have this code:

public void GetRole ( )
{
StringBuilder sbld = new StringBuilder ( );
System.AppDomain.CurrentDomain.SetPrincipalPolicy ( PrincipalPolicy.WindowsPrincipal );
WindowsIdentity curIdentity = WindowsIdentity.GetCurrent ( );
WindowsPrincipal myPrincipal = new WindowsPrincipal ( curIdentity );
List<string> groups = new List<string> ( );
foreach ( IdentityReference irc in curIdentity.Groups )
{
groups.Add ( ( ( NTAccount )irc.Translate ( typeof ( NTAccount ) ) ).Value );
}

sbld.Append ( "Name: " + curIdentity.Name + " System: curIdentity.IsSystem " + " Authenticated: " +
curIdentity.IsAuthenticated + " BuiltinAdmin: " + "Identiry: " +
myPrincipal.IsInRole ( WindowsBuiltInRole.Administrator ).ToString ( ) +
myPrincipal.Identity + string.Join ( string.Format ( ",{0}tt", Environment.NewLine ), groups.ToArray ( ) ) );
Console.WriteLine ( @"Name: {0} System: {1} Authenticated: {2} BuiltinAdmin: {3} Identity: {4} Groups: {5}",
curIdentity.Name, curIdentity.IsSystem, curIdentity.IsAuthenticated,
myPrincipal.IsInRole ( WindowsBuiltInRole.Administrator ) ? "True" : "False",
myPrincipal.Identity,
string.Join ( string.Format ( ",{0}tt", Environment.NewLine ), groups.ToArray ( ) ) );
try
{
Console.WriteLine ( Environment.NewLine );
}
catch ( System.Security.SecurityException scx )
{
Console.WriteLine ( scx.Message + " " + scx.FirstPermissionThatFailed.ToString ( ) );
}
Console.WriteLine(Environment.NewLine);
} // GetRole


I get this Exception at runtime:

System.Security.SecurityException

What is the reason. I am the administrator on this computer.
