Examples

The following code example shows the use of the GacInstalled class.

C#

using System;
using System.Security.Policy;
using System.Security;
using System.Security.Permissions;

namespace GacClass
{
    class GacDemo
    {
        [STAThread]
        static void Main(string[] args)
        {
            GacInstalled myGacInstalled = new GacInstalled();

            Object [] hostEvidence = {myGacInstalled};
            Object [] assemblyEvidence = {};
            Evidence myEvidence = new Evidence(hostEvidence,assemblyEvidence);
            GacIdentityPermission myPerm = 
                (GacIdentityPermission)myGacInstalled.CreateIdentityPermission(
                myEvidence);
            Console.WriteLine(myPerm.ToXml().ToString());

            GacInstalled myGacInstalledCopy = 
                (GacInstalled)myGacInstalled.Copy();
            bool result = myGacInstalled.Equals(myGacInstalledCopy);

            Console.WriteLine(
                "Hashcode = " + myGacInstalled.GetHashCode().ToString());

            Console.WriteLine(myGacInstalled.ToString());
        }
    }
}

Remarks

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

The presence of GacInstalled evidence produces a GacIdentityPermission in the grant set. If there is a Demand for GacIdentityPermission, the GacIdentityPermission that corresponds to the GacInstalled evidence is compared with the demanded permission.

Constructors

GacInstalled()

Initializes a new instance of the GacInstalled class.
