Question

我使用Nuget将HTML Agility Pack（HAP）添加到我的解决方案中。我的解决方案使用Silverlight 5.我可以通过“使用HtmlAgilityPack”调用一些函数。但有些功能我不能打电话。我需要通过以下代码行获取URL的内容：

string Url = "http://google.com.vn"; // this line is okay
HtmlWeb web = new HtmlWeb(); // this line is okay
HtmlDocument doc = web.Load(Url); // but this line is highlighted with an error 'Error HtmlAgilityPack.HtmlWeb' does not contain a definition for 'Load' and no extension method 'Load' accepting a first argument of type 'HtmlAgilityPack.HtmlWeb' could be found (are you missing a using directive or an assembly reference?)'
