您可以使用HtmlAgilityPack轻松地从HTML中提取信息。例如：

var html = @"<p style=""text-align: center;""><img hspace=""1"" height=""312"" border=""1"" align=""middle""                              width=""300"" vspace=""3"" src=""/recipeuserfiles/Katte Pongali-andhra recipes-healthy recipes.PNG"" alt="""" /></p> <ul> <li>Mix the rice and Green gram dal Cook in pressure cooker and keep it side. </li> <li>Now take a vessel and heat the ghee and add add pepper, cumin seeds, curry leaves and cashew nuts to it. </li> <li>Then add the cokked rice and dal , salt and mix it properly. </li> <li>Delicious pongali is ready to taste. Have it with any of your favorite chutney.</li> </ul>";
var doc = new HtmlDocument();
doc.LoadHtml(html);
var src = doc.DocumentNode.SelectSingleNode("//img").GetAttributeValue("src", "");

//this will print /recipeuserfiles/Katte Pongali-andhra recipes-healthy recipes.PNG
Console.WriteLine(src);
