The following example shows how to create and set the properties of an XpsSignatureDefinition.
private void SignatureDefinitionCommandHandler(object sender, RoutedEventArgs e)
{
SignatureDefinition sigDefDialog = new SignatureDefinition();
if (sigDefDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
XpsSignatureDefinition signatureDefinition = new XpsSignatureDefinition();
signatureDefinition.RequestedSigner = sigDefDialog.RequestedSigner.Text;
signatureDefinition.Intent = sigDefDialog.Intent.Text;
signatureDefinition.SigningLocale = sigDefDialog.SigningLocale.Text;
try
{
signatureDefinition.SignBy = DateTime.Parse(sigDefDialog.SignBy.Text);
}
catch (FormatException)
{
}
signatureDefinition.SpotId = Guid.NewGuid();
IXpsFixedDocumentSequenceReader docSeq = _xpsDocument.FixedDocumentSequenceReader; //_xpsDocument is type System.Windows.Xps.Packaging.XpsDocument
IXpsFixedDocumentReader doc = docSeq.FixedDocuments[0];
doc.AddSignatureDefinition(signatureDefinition);
doc.CommitSignatureDefinition();
InitializeSignatureDisplay();
}
}
