//Copy creates and returns an identical copy of the current permission.
bool CopyDemo()
{
    bool returnValue = true;
    StrongNameIdentityPermission^ snIdPerm1;
    StrongNameIdentityPermission^ snIdPerm2;
    snIdPerm1 = gcnew StrongNameIdentityPermission(blob, "MyCompany.MyDepartment.*", gcnew Version("1.0.0.0"));
    snIdPerm2 = gcnew StrongNameIdentityPermission(PermissionState::None);

    snIdPerm2 = dynamic_cast<StrongNameIdentityPermission^>(snIdPerm1->Copy());
    Console::WriteLine("Result of copy = " + snIdPerm2->ToString() + "\n");

    return returnValue;
}

//Copy creates and returns an identical copy of the current permission.
private bool CopyDemo()
{
    bool returnValue = true;

    StrongNameIdentityPermission snIdPerm1, snIdPerm2;

    snIdPerm1 = new StrongNameIdentityPermission(blob, "MyCompany.MyDepartment.*", new Version("1.0.0.0"));
    snIdPerm2 = new StrongNameIdentityPermission(PermissionState.None);

    snIdPerm2 = (StrongNameIdentityPermission)snIdPerm1.Copy();
    Console.WriteLine("Result of copy = " + snIdPerm2.ToString() + "\n");

    return returnValue;
}

'Copy creates and returns an identical copy of the current permission.

    Dim returnValue As Boolean = True
    
    Dim snIdPerm1, snIdPerm2 As StrongNameIdentityPermission
    
    snIdPerm1 = New StrongNameIdentityPermission(blob, "MyCompany.MyDepartment.*", New Version("1.0.0.0"))

    snIdPerm2 = CType(snIdPerm1.Copy(), StrongNameIdentityPermission)
    Console.WriteLine("Result of copy = " + snIdPerm2.ToString() + vbLf)
