Compare it with this...which works:
// Create the policy statement.
NamedPermissionSet namedPS = new NamedPermissionSet("FullTrust");
PolicyStatement ps = new PolicyStatement(namedPS);
ps.Attributes = PolicyStatementAttribute.Exclusive;
// Create the membership condition.
string url = "http://www.dummycorp.com";
UrlMembershipCondition condition = new UrlMembershipCondition(url);
// Create the code group.
UnionCodeGroup proplanner = new UnionCodeGroup(condition, ps);
proplanner.Name = "MyCodeGroup";
proplanner.Description = "Allows fully-trusted access to the URL.";
// Find the machine policy level.
PolicyLevel machine = null;
IEnumerator ie = SecurityManager.PolicyHierarchy();
while (ie.MoveNext())
if (String.Compare(((PolicyLevel)ie.Current).Label, "Machine", true) == 0)
machine = (PolicyLevel)ie.Current;
// If the machine policy level was not found, throw an exception.
if (machine == null)
throw new InstallException("Unable to find the Machine policy level.");
// Enumerate the root code group children and
// determine if the Proplanner group already exists.
bool exists = false;
foreach (CodeGroup group in machine.RootCodeGroup.Children)
{
if (proplanner.Equals(group))
{
exists = true;
break;
}
}
// If the code group doesn't exist, add it.
if (!exists)
{
// Add our code group to the root code group.
machine.RootCodeGroup.AddChild(proplanner);
SecurityManager.SavePolicyLevel(machine);
}
