Get current/active security zone of a .NET application?

Question

I have an application that behaves oddly, and just to verify, I\'d like to see which security zone it is currently running under.

I\'ve found the System.Security.Sec

Answer 1

You can also use

Evidence e = Thread.CurrentThread.GetType().Assembly.Evidence;

instead of

this.GetType().Assembly.Evidence

Answer 2

You need to look at the CAS evidence for the current assembly;

this.GetType().Assembly.Evidence

Assembly.Evidence is a property Evidence object. From this you can enumerate the evidence and look for the zone which appears as a <System.Security.Policy.Zone> element.

Answer 3

In .NET 3.5 you can simplify the code with LINQ:

Zone z = a.Evidence.OfType<Zone>().First();

From .NET 4.0 you have a convenient GetHostEvidence method:

Zone z = Assembly.GetExecutingAssembly().Evidence.GetHostEvidence<Zone>();

Note that from .NET 4.0 evidence classes derive from the EvidenceBase base class.
