ObjectiveC # generics have always been a topic for learners, and this is really a very useful feature, but there are still a lot of things to be aware of in practice, and we need to understand them through hands-on practice and a combination of

C # serialization is convenient. You simply define the type. But sometimes there are wonderful problems. Are you experiencing any of the following problems?This problem has plagued me for a long time. Finally, finally solved. Method is really

"Problem""Analysis"Each type referenced in the formal parameter list of a return type and method must have at least the same accessibility as the method itself.One is that the access level of the return parameter is less than the access level of the

What is an interface? In fact, the interface is a simple understanding is a convention, so that the implementation of the interface class or structure in the form of consistency. Personally, the use of interfaces can make programs clearer and more

1.this.   Close (); Just close the current window, if it is not the main form, you can not quit the program, and if there is a managed thread (not the main threads), also can not cleanly exit;2.application.exit (); Forces all messages to abort,

Knowledge pointsThe value type.The value type allocates memory on the stack, is initialized at declaration time, and cannot be null.Value type out of scope system automatically frees memory.Mainly consists of two categories: structure, Enumeration
