What is the new operator of C,

What happened to the creation of objects using the new operator?

 

There is a parent class Animal, Dog derived from Animal.

    class Program
    {
        static void Main(string[] args)
        {
            Dog dog = new Dog();
Console. WriteLine ("I can call the instance method GetType of the ancestor Object, and the result is:" + dog. GetType ());
Console. WriteLine ("I can get the property Age =" + dog. Age of the parent class );
Console. WriteLine ("of course I can get my own public field _ weight =" + dog. _ weight );
            
        }
    }
    public class Animal
    {
        public int Age { get; set; }
        public Animal(){}
    }
    public class Dog : Animal
    {
        public decimal _weight;
        public Dog(){}
    }

Although a subclass Dog instance is created, the "ancestor" System can be called through the dog instance. object instance method can also obtain the value of the common attribute Age of the parent class, And all instance field values are the default values of its type.

 

The new operator performs the following operations:

→ Calculate the number of bytes occupied by the Dog class and all parent class instance fields
→ Calculate the number of bytes occupied by the Dog class and all parent classes "type object pointers" and "synchronized block indexes"
→ Memory allocation based on the number of bytes in the managed heap
→ Call the constructor of all parent classes, and then call the constructor of Dog. During this process, all instance fields are initialized. The field value is the default value of the field type or the real parameter value of the constructor. The "type Object Pointer" and "synchronization block Index" members are initialized.
→ Assign the heap address of the newly created Dog instance to the stack variable dog
→ Managed heap objects created through new are eventually recycled by GC

Refer to this to clean up the C drive:
1. Disable System Restoration: My computer properties/System Restoration/disable System Restoration on all disks, but I will not be able to use system restoration in the future!
2. Disable System sleep: Control Panel/Power Supply/sleep/remove the check before starting system sleep
3. move the virtual memory, my computer properties/advanced/performance/settings/advanced/change/select the C disk, that is, the system disk, select the no-score page, and then set the virtual memory to its disk, A disk with more disk space remaining, such as D, E, and F. set to 1.5 ~ of memory ~ 2.5 times. The size can be set to the same!
5. Clear temporary IE folders, internet Options, and delete temporary and offline files.
6. delete system logs and program logs, my computer/control panel/management tools/Computer Management/Event Viewer/application, right-click/clear events, and clear system logs in sequence
7. Clear system cache: 2000 all files in the system: C: \ WINNT \ system32 \ dllcache
The XP system is: C: \ windows \ system32 \ dllcache all files under the system cache (open my computer/tool/file and Folder Options/hide the protected system file hook off to hide all files on the hook) ). You can also run the sfc.exe/purgecache command to automatically delete the file.
8. Clear the recycle bin
9. delete the files under c: \ windows \ SoftwareDistribution \ Download (the files downloaded when the system is updated are useless if you have installed the updates)
10. Delete all directories under c: \ windows \ RegisteredPackages
11. Delete all Files under C: \ WINDOWS \ Downloaded Program Files
12. view the hidden files that are known to be protected by the system in my computer folder option, and check all the files.
13. Delete c: \ windows \ All files with $8882305 $ (backup files after system update)
