StorePermissionAttribute.Flags Property

Caution:
Many of these flags are powerful and permit access to stores that should be granted only to highly trusted code.

The most powerful of the flags are AddToStore, CreateStore, DeleteStore, and AllFlags. For specific threats posed by the use of these flags, see individual flag descriptions.

The following code example shows the use of the Flags property to deny the ability to add to a store. This code example is part of a larger example provided for the StorePermission class.

//Deny the permission the ability to add to a store.
[StorePermission(SecurityAction.Deny, Flags = StorePermissionFlags.AddToStore)]
private static void AddToStore(X509Certificate2 cert)
{
    try
    {
        X509Store store = new X509Store("teststore", StoreLocation.CurrentUser);

        store.Open(OpenFlags.ReadWrite);

        // The following attempt to add a certificate results in an exception being thrown.
        store.Add(cert);
        return;
    }
    catch (SecurityException e)
    {
        Console.WriteLine("Security exception thrown when attempting: " + 
            ((StorePermission)e.FirstPermissionThatFailed).Flags);
        return;
    }
}
