C＃中变量和对象有什么区别？ [英] What is the difference between variable and object in C# ?

问题描述

让我说我有一个班级建筑

let's say that i have a Class Building

Building house = new Building();

现在我正在读一本书，上面写着

now i was reading in a book that say that

Quote：

这个声明执行三个功能。首先，它声明了一个名为House of

类类型Building的变量。这个变量本身不是一个对象。相反，它只是一个变量，

可以引用一个对象。

This declaration performs three functions. First, it declares a variable called house of the
class type Building. This variable is not, itself, an object. Instead, it is simply a variable that
can refer to an object.

然后我遇到了一个Answerin Stackoverflow说是那个

and then i am came across a Answerin Stackoverflow that say's that

引用：

如果你看一个例子，他很容易理解。例如，假设您有一个House House。你自己的房子是一个对象，是House之类的一个例子。你姐姐的房子是另一个对象（House的另一个例子

his is easy to understand if you look at an example. For example, suppose you have a class House. Your own house is an object and is an instance of class House. Your sister's house is another object (another instance of class House

// Class House describes what a house is
class House {
    // ...
}

// You can use class House to create objects (instances of class House)
House myHouse = new House();
House sistersHouse = new House();

现在我很困惑它是一个物体还是变量？

ps：我是C＃的新手



我尝试了什么：



阅读了很多文章但很困惑

now i am confused whether it's an object or an Variable?
ps: i am new to C#

What I have tried:

read many articles but confused

推荐答案

变量只是类型的名称，我们基本上在
/library/view/programming-c-40/9781449392192/ch04s08.html\">c#一切都是对象 [ ^ ]（所有类型都来自对象）



简单单词，用于值类型 [ ^ ]我们将其称为变量 [ ^ ]其中参考类型 [ ^ ]我们称之为对象 [ ^ ]



例如：

Variable is just a name given to the type which we create
basically in c# everything is an object[^] (all the types are derived from object )

In simple words, For Value types[^] we will call it as variables [^] where as for reference type[^] we call it as object [^]

example:

 int i; 
//  i is a variable name for the  value type  int

MyClass objMyClass ;
 //objMyClass is an object(variable name) of type MyClass which is a  reference type
