Notes 61. Each class has only one class variable, and objects belonging to that class share the class variable. You do not need to access class variables through objects.62. A static method can only access the static data of a class; A static method

Lambda expression is clearer than the combination of definition and Out-of-band method definitions, and the additional work involved is only required to satisfy the language definition. However, it also has some deficiencies. If the parameter of a

Use of static Sometimes you want to define a class member so that its use is completely independent of any object of that class. Typically, a class member must be accessed through the object of its class, but it

For a type, if we do not want to or cannot change it, but want to add a method for this type, we can use the extension method. If this type has a higher level of abstraction, such as an interface, we should compile an extension method for a higher
