推荐答案

对于后期绑定错误，您需要将您尝试设置的对象强制转换为正确的数据类型，因为 WP7 不支持类型的运行时评估(后期绑定).

For the late binding error, you need to cast the object you are trying to set to the correct data type, as WP7 doesn't support runtime evaluation of types (late-binding).

至于GetWebResponse的错误，编译器绝对正确，WebRequest(甚至HttpWebRequest)没有GetWebResponse 方法，也许您正在寻找 WebRequest.GetResponse?

As for the error with GetWebResponse, the compiler is absolutely correct, WebRequest (or even HttpWebRequest) does not have a GetWebResponse method, perhaps you were looking for WebRequest.GetResponse?

例如:

response = request.GetResponse(); // where request is of type WebRequest or a derived class
