try
{
    StreamReader sr = File.OpenText(xrmlFile);
    xrmlString = sr.ReadToEnd();
}
catch (Exception ex)
{
    MessageBox.Show("ERROR: '"+xrmlFilename+"' open failed.\n"+
        "Exception: " + ex.Message, "XrML File Error",
        MessageBoxButton.OK, MessageBoxImage.Error);
    return false;
}

WriteStatus("   Building UnsignedPublishLicense");
WriteStatus("       from '" + xrmlFilename + "'.");
UnsignedPublishLicense unsignedLicense =
    new UnsignedPublishLicense(xrmlString);
ContentUser author = unsignedLicense.Owner;

WriteStatus("   Reading '" & xrmlFilename & "' permissions.")
Try
    Dim sr As StreamReader = File.OpenText(xrmlFile)
    xrmlString = sr.ReadToEnd()
Catch ex As Exception
    MessageBox.Show("ERROR: '" & xrmlFilename &"' open failed." & vbLf & "Exception: " & ex.Message, "XrML File Error", MessageBoxButton.OK, MessageBoxImage.Error)
    Return False
End Try

Dim author As ContentUser = unsignedLicense.Owner

Comentários

O publishLicenseTemplate XrML <RANGETIME> ou <INTERVALTIME> elementos são ignorados quando o UnsignedPublishLicense construtor é criado pelo UnsignedPublishLicenseconstrutor (String). Para especificar esses valores para a licença de publicação, as ContentGrant propriedades devem ValidFrom ValidUntil ser definidas explicitamente. O exemplo a seguir mostra como definir explicitamente as propriedades e ValidUntil as ValidFrom propriedades.

// The XRML template <RANGETIME> and <INTERVALTIME> elements are
// ignored by the UnsignedPublishLicense(xrmlString) constructor.
// To specify these values for the license, the ContentGrant
// ValidFrom and ValidUntil properties must be explicitly set.
// The following code sample demonstrates how to set the
// ContentGrant properties for ValidFrom and ValidUntil.

// Create a copy of the original XRML template ContentGrants
// set by the UnsignedPublishLicense(xrmlString) constructor.
ICollection<ContentGrant> tmpGrants = new List<ContentGrant>();
foreach (ContentGrant grant in unsignedLicense.Grants)
    tmpGrants.Add(grant);

// Erase all original UnsignedPublishLicense ContentGrants.
unsignedLicense.Grants.Clear();

// Add each original grant back to the UnsignedPublishLicense
// with appropriate ValidFrom and ValidUntil date/time values.
foreach (ContentGrant grant in tmpGrants)
{
    unsignedLicense.Grants.Add( new ContentGrant(
        grant.User, grant.Right,
        DateTime.MinValue,    // set ValidFrom as appropriate
        DateTime.MaxValue));  // set ValidUntil as appropriate
}
