GacInstalled Class

Definition

Namespace:

System.Security.Policy

Assembly:

System.Security.Permissions.dll

Caution

Code Access Security is not supported or honored by the runtime.

Confirms that a code assembly originates in the global assembly cache (GAC) as evidence for policy evaluation. This class cannot be inherited.

Examples

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

using namespace System;
using namespace System::Security::Policy;
using namespace System::Security;
using namespace System::Security::Permissions;

[STAThread]
int main()
{

    GacInstalled ^ myGacInstalled = gcnew GacInstalled;

    array<Object^>^hostEvidence = {myGacInstalled};
    array<Object^>^assemblyEvidence = {};
    Evidence^ myEvidence = gcnew Evidence( hostEvidence,assemblyEvidence );
    GacIdentityPermission ^ myPerm = dynamic_cast<GacIdentityPermission^>
        (myGacInstalled->CreateIdentityPermission( myEvidence ));
    Console::WriteLine( myPerm->ToXml() );

    GacInstalled ^ myGacInstalledCopy = 
        dynamic_cast<GacInstalled^>(myGacInstalled->Copy());
    bool result = myGacInstalled->Equals( myGacInstalledCopy );

    Console::WriteLine( "Hashcode = {0}", myGacInstalled->GetHashCode() );

    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.

Methods

Clone()	Creates a new object that is a complete copy of the current instance. (Inherited from EvidenceBase)
Copy()	Creates an equivalent copy of the current object.
CreateIdentityPermission(Evidence)	Creates a new identity permission that corresponds to the current object.
Equals(Object)	Indicates whether the current object is equivalent to the specified object.
GetHashCode()	Returns a hash code for the current object.
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string representation of the current object.
