Field vs Static Field，基本问题...... [英] Field vs Static Field, basic question...
问题描述
我希望这是一个发布真正初学者的好地方。
基本上我需要知道字段和静态字段之间的区别。
我的书sux并没有解释清楚。似乎一个字段的范围相同，并且可以做同样的事情。
IE字段是在一个类而不是一个方法中声明的，所以
类可以使用它。
我的书中描述的静态字段是相同的吗？
我必须遗漏一些东西...
I hope this is an ok place to post real beginner stuff.
Basically I need to know the difference between a field, and a static field.
My book sux and doesn''t explain this well. It seems that a field is scoped
the same and can do the same things.
IE a field is declared in a class instead of a method so all methods of the
class can use it.
And a static field is described in my book as the same?
I must be missing something...

它与静态方法和实例
方法，静态属性和实例属性之间的区别相同。
任何静态是一般的类型，而不是任何特定的类型的b $ b实例。 （例如，您可以使用静态字段来计算已创建了多少个b $ b实例。）
任何非静态的特定于该特定实例的。 （你可以
使用一个实例字段来说，例如，这个实例是< n>创建了一个
。）

It''s the same difference as between a static method and an instance
method, and a static property and an instance property.
Anything "static" is to do with the type in general, not any particular
instance of the type. (You might use a static field to count how many
instances have been created, for example.)
Anything non-static is specific to that particular instance. (You might
use an instance field to say, "This instance was the <n>th one to be
created, for example.)

A字段（根据我的理解，是没有财产声明的财产
（公共变量））。
除此之外，适用于财产的所有内容都适用于字段
（静态vs实例等......）
即
公共类x
{
private int m_x; // private var x
public int y; // field var y
private static int m_X; // private static var X
public static int Y; //静态字段Y
public int x //实例属性
{
set
{
返回m_x;
}
get
{
m_x = value ;
}
public static int X //静态属性
{
get
{
返回m_X;
}
设定
{
m_X =价值;
}
}
A field (from what I understand is a property without a property declaration
(public variable)).
Apart from that everything that applies to properties applies to fields
(static vs instance etc...)
ie
public class x
{
private int m_x; //private var x
public int y; //field var y
private static int m_X; //private static var X
public static int Y; //static field Y
public int x //instance property
{
set
{
return m_x;
}
get
{
m_x = value;
}
public static int X //static property
{
get
{
return m_X;
}
set
{
m_X = value;
}
}

编号字段是变量。一个属性根本不需要变量
支持它。
除了适用于属性的所有内容都适用于字段

No. A field is a variable. A property doesn''t have to have a variable
backing it at all.

好吧，很多东西，但不是一切。例如，一个属性
不能通过引用传递。
属性本质上是一种方法（或一对方法）和一点点
元数据允许使用类似字段的语法访问这些方法。
但是，静态的意思是静态。对于所有会员类型都是一样的。

Well, lots of things, but not everything. For instance, a property
can''t be passed by reference.
A property is essentially a method (or pair of methods) and a bit of
metadata to allow those methods to be accessed using field-like syntax.
But yes, the meaning of "static" is the same for all member types.
