xelement

问题 Somewhere in a C# program, I need to get an attribute value from an xml structure. I can reach this xml structure directly as an XElement and have a simple xpath string to get the attribute. However, using XPathEvaluate, I get an empty array most of the time. (Yes, sometimes, the attribute is returned, but mostly it isn't... for the exact same XElement and xpath string...)

问题 I'm generating XML file from structs. Some struct members are in List<T> type. I'm using linq queries but I'm stuck at some level. My structs are like this: public struct Project { public string name; public List<Class> classes; } public struct Class { public string name; public int class_id; public List<Var> vars; } public struct Var { public string name; public string description; public int var_id; public List<Element> elements; } public struct Element { public string name; public string

问题 I have a .NET Web Service(.asmx, not .svc) that accepts a string via HTTP POST. The strings it accepts are xml infosets I then parse via XElement.Parse.
