Exemplos

O exemplo a seguir cria uma mensagem e consultas de mensagem XPath.The following example creates a message and XPath message queries. As consultas são avaliadas pelos XPathMessageQuery objetos contidos em um XPathMessageQueryCollection objeto.The queries are evaluated by the XPathMessageQuery objects contained in an XPathMessageQueryCollection object. Os resultados de cada consulta são testados usando ResultType a propriedade XPathResult da classe.The results of each query are tested using the ResultType property of the XPathResult class.
