推荐答案

您好，

您可以这样做。

 string s =
                "<description><p style=\"text-align: center;\"><span style=\"color: rgb(128, 0, 0);\"><strong><span style=\"font-size: medium;\">Peas Masala Rice Recipe <br /> </span></strong></span></p> <p style=\"text-align: center;\"><span style=\"color: rgb(128, 0, 0);\"><strong><span style=\"font-size: medium;\"><img width=\"300\" vspace=\"3\" hspace=\"1\" height=\"250\" border=\"1\" align=\"middle\" src=\"/recipeuserfiles/Peas Masala Rice Recipe.jpg\" alt=\"\" /></span></strong></span></p> <p><strong>Ingredients <br /> </strong></p> <p>* 1 cup Rice</p> <p>* 1/2 Coconut</p> <p>* 2 Green Chillies</p> <p>* 1 small Ginger</p> <p>* 1/2 cup Green Peas</p> <p>* 2 tsp Oil</p> <p>* 2 Cardamoms</p> <p>* 4 Cloves</p> <p>* 1 Cinnamon</p> <p>* Salt to taste</p> <p>* Coriander leaves</p> <p>* Mustard seeds</p> <p>nbsp;</p> <p><strong>Preparation <br /> </strong></p> <p>* First grind coconut (grated), ginger, cinnamon, cloves, green chillies, cardamom to a smooth paste by adding little water.</p> <p>* In a pressure pan, add oil and add mustard seeds to the ground masala and saute well.</p> <p>* Clean the rice in running water and add to the masala.</p> <p>* Stir well for two minutes.</p> <p>* Add the green peas, 2 1/4 cup water and salt.</p> <p>* Close the pressure pan. Keep for 2 or 3 sounds.</p> <p>* Remove from fire.</p> <p>* When the pressure becomes normal, transfer the bath in a bowl and stir it.</p> <p>* Garnish with coriander leaves.</p></description>";

            XDocument doc = XDocument.Parse(s);

            if (doc.Descendants("img").Any())
            {
                var imgTag = doc.Descendants("img").First();

                var width = imgTag.Attribute("width").Value;
            }

如果你想访问一个元素的值，那么你可以这样做

If you want to access the value of an element, then you could do something like this

 var value_of_an_elemnt= imgTag.Value;
