"Learning notes" C # static Class

• Static modifiers
  • A static member is a member that is decorated with static
  • A static member can only be called by a class
  • Classes that are decorated with static are static classes
  • A static class cannot be instantiated and can contain only static members and const constants
• A total of five areas in memory
  • 1. Heap area-requires programmer to manually open and manage memory
  • 2. Stack area-automatic memory management by the system
  • 3. Static zone (global Zone)-the data is always present during the sequence operation
  • 4. Constant zone-for holding constants
  • 5. Code area-the code required to store the program's operation
• Static construction
  • The construction method can also be set to static
  • Static constructs cannot have parameters and access modifiers
  • Static constructs can be used, whether it is a static class or not
  • Static constructs are invoked the first time a static member is instantiated or called
