价值类型 - 结构 [英] Value Types - Structures
问题描述
大家好，
微软称结构是价值类型。原始数据类型
是值类型。值类型的内存在堆栈上分配。然后
为什么我们需要新的运算符为结构值类型分配内存而不是原始数据类型的
（它们也在堆栈上分配内存）？请
帮助。
提前致谢。

Hi All,
Microsoft says that structures are value types. Also primitive data types
are value types. And memory for value types is allocated on the stack. Then
why we need new operator to allocate memory for structure value types and not
for primitive data types(they r allocated memory on stack as well)??? Please
help.
Thanks in advance.

推荐答案
hi
结构在堆栈上分配。
'new''的作用是将值类型'的字段初始化为null / zero
问候

" faktujaa"写道：
hi
the struct gets allocated on the stack.
What ''new '' does is initialize the value type''s fields to null/zero

值类型的内存在某些情况下仅在堆栈上分配。

Memory for value types is only allocated on the stack in some cases.

types and not for primitive data types(they r allocated memory on

" new"只是意味着调用构造函数。它没有任何关系
分配的地方。

"new" just means "call a constructor". It doesn''t have anything to do
with where things are allocated.

新的与分配无关记忆它用于调用
构造函数。
所以通过使用带结构的new，你调用的是
结构的构造函数将其所有成员变量设置为0，false或null取决于
其类型

" ; Jon Skeet [C＃MVP]"写道：
New has nothing to do with allocation of memory. It is used to call the
constructor.
so by using the new with a structure , you are calling a constructor of the
structure which sets all its members variables to 0, false or null depending
on their type
