dynamic

问题 I am try to add a dynamic method to ExpandoObject which would return the properties (added dynamically) to it, however it's always giving me error. Is something wrong I am doing here? using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Dynamic; namespace DynamicDemo { class ExpandoFun { public static void Main() { Console.WriteLine("Fun with Expandos..."); dynamic student = new ExpandoObject(); student.FirstName = "John"; student.LastName = "Doe"

问题 I have a static and a dynamic library with the same name: libclsocket.a and libclsocket.so When I specify what library I want to link to i simply enter -lclsocket as the library. My program complies and runs perfectly fine, but what library am I using? the static library or the dynamic library? I want to give my friend my program, and I'm not sure If i need to include the libraries in the release.

问题 If you had the following: class Animal{}; class Bird : public Animal{}; class Dog : public Animal{}; class Penguin : public Bird{}; class Poodle : public Dog{}; Does dynamic_cast just check if one class is a derived class of another, or if one class is a base class of another? So if I had: Bird* bird; Animal* animal; bird = dynamic_cast<Animal*>(bird); animal = dynamic_cast<Bird*>(animal); bird would now point to an Animal class, so that I can use bird->some_function(); and it will call the
