A static member of a class is a love-hate trait. I decided to summarize the knowledge points of static class members so that I would not be passive on such issues in future interviews.Static class members include both static data members and static

Extension methodsAdd a method dynamically to an existing type without creating a new derived type, recompiling or modifying the source of the original type An extension method is a special static method that is called in the same way as a normal

It is not possible to know the length of an indexer by means of a method, only to set a fixed length, so the indexer can only initialize a finite array of lengths, or use string as a key class Program { static void

This topic uses the Add () method of the. NET 3.5 in the System.Collections.Generic namespace that contains a new collection class:hashset, for more information, see reprint: C # HashSet usage.Topic:Given an array of integers and a integer K, find

From the point of view of memory execution, the value type of memory is allocated on the stack of threads, whereas the memory of the reference type is allocated on the managed heap. Therefore, conversions from value types to reference types are
