例

次の例では、 プロパティを使用して を BoundGrants 介して付与されたリスト権限を取得する方法を UseLicense示します。

ShowStatus("   Binding UseLicense with the SecureEnvironment" +
         "\n       to obtain the CryptoProvider.");
CryptoProvider cryptoProvider = useLicense.Bind(_secureEnv);

ShowStatus("   Obtaining BoundGrants.");
ReadOnlyCollection<ContentGrant> grants =
    cryptoProvider.BoundGrants;

rightsBlockTitle.Text = "Rights - " + Filename(useLicenseFile);
rightsBlock.Text = "GRANTS LIST\n-----------------\n";
foreach (ContentGrant grant in grants)
{
    rightsBlock.Text += "USER:  " + grant.User.Name + " [" +
        grant.User.AuthenticationType + "]\n";
    rightsBlock.Text += "RIGHT: " + grant.Right.ToString() + "\n";
    rightsBlock.Text += "    From:  " + grant.ValidFrom + "\n";
    rightsBlock.Text += "    Until: " + grant.ValidUntil + "\n";
}

if (cryptoProvider.CanDecrypt == true)
    ShowStatus("   Decryption granted.");
else
    ShowStatus("   CANNOT DECRYPT!");

ShowStatus("   Binding UseLicense with the SecureEnvironment" & vbLf & "       to obtain the CryptoProvider.")
Dim cryptoProvider As CryptoProvider = useLicense.Bind(_secureEnv)

ShowStatus("   Obtaining BoundGrants.")
Dim grants As ReadOnlyCollection(Of ContentGrant) = cryptoProvider.BoundGrants

rightsBlock.Text = "GRANTS LIST" & vbLf & "-----------------" & vbLf
For Each grant As ContentGrant In grants
