is automatic unpacking and automatic boxing Automatic Boxing: The base type is packaged with their corresponding packing class so that they have the object's characteristics and can invoke the method defined by the corresponding wrapper class, such as ToString (). As an example: Integer i0 = new Integer (0); Integer i1 = 2; Integer i1_ = integer.valueof (2); The first line of the top three lines

In the CLR, in order to convert a value type to a reference type, a mechanism called boxing is used.The following summarizes what happens inside a boxing operation on one instance of a value type: 1) allocates memory in the managed heap. The amount of memory allocated is the amount of memory required for each field of a value type plus two additional members for all objects on the managed heap (type Object

When it comes to packing and unpacking, Debuglzq believes that the Bo friends in the garden must be able to tell the way, presumably meaning that the value type and the reference type of the mutual conversion of the---value type to the reference type is called boxing, the other is called unboxing. This certainly no problem, but you only know so much, then debuglzq suggest you take some time to see the landlord this article, continue the previous sever

The problem of automatic boxing and unboxing is a cliché in Java, and today we'll take a look at some of the problems in boxing and unboxing. This article first about boxing and unpacking the most basic things, and then look at the interview written in the often encountered with the box, unpacking related issues. The following is a table of contents outline for

Net Is divided into two types, one is a value type, and the other is a reference type. The essential difference between these two types is that the value type data is allocated on the stack, while the reference type data is allocated on the heap. Then, if you want to put a value type data on the heap, you need a boxing operation, conversely, a value type data placed on the heap is taken out, you need to do the unpacking operation. For example, for the

Boxing: Value types are "light" than reference types because they are not allocated as objects in the managed heap, are not garbage collected, and are not referenced by pointers. However, there are many times when you need to get a reference to a value type, for example, suppose you want to create a ArrayList object to hold a set of point structures, with the following code: public sealed class Program{public static void Main () { ArrayList a = new Ar
